Benjamin Franklin Bridge

The Benjamin Franklin Bridge is a suspension bridge that spans the Delaware River, connecting Center City Philadelphia, Pennsylvania, to Camden, New Jersey, and serving as a vital transportation link for both vehicular and rail traffic.^[1] Originally named the Delaware River Bridge upon its completion in 1926, it was renamed the Benjamin Franklin Bridge on January 17, 1956, to honor the Philadelphia-born Founding Father and polymath on the 250th anniversary of his birth.^[2] With a main span of 1,750 feet (533 meters), a total length of 7,456 feet (abutment to abutment), and towers rising 382 feet (116 meters) high, it held the distinction of being the world's longest suspension bridge when it opened on July 1, 1926.^[1]^[3] Construction of the bridge began on January 6, 1922, under the direction of chief engineer Ralph Modjeski of the firm Modjeski and Masters, with architectural design by Paul Philippe Cret and structural engineering contributions from Leon Moisseiff, who applied his innovative deflection theory for load distribution.^[4]^[3] The project, authorized by joint legislation from Pennsylvania and New Jersey in 1919, cost approximately $37 million and utilized 70,851 tons of structural steel, with caisson foundations sunk into the riverbed for the main piers.^[1]^[5] The bridge opened on July 1, 1926, as part of the Sesquicentennial Exposition, with a pedestrian procession attended by over 100,000 people and vehicular traffic beginning that evening, marking the end of reliance on ferries that had crossed the Delaware since colonial times.^[6]^[7] Owned and operated by the Delaware River Port Authority (DRPA), the bridge carries Interstate 676 and U.S. Route 30 across its seven traffic lanes, alongside the Port Authority Transit Corporation (PATCO) high-speed rail line and a dedicated pedestrian/bicycle walkway elevated 135 feet (41 meters) above the river.^[1]^[8] Tolls for passenger vehicles were increased to $6.00 (E-ZPass) effective September 1, 2024.^[9] It handles approximately 34.1 million vehicles annually as of 2024, underscoring its role as a critical artery for commerce, commuting, and regional connectivity between the Philadelphia metropolitan area and southern New Jersey.^[1] Notable features include a computer-controlled lighting system installed for the U.S. Bicentennial in 1976, which illuminates the cables in dynamic patterns for events and holidays, and artistic elements such as a 101-foot lightning bolt sculpture referencing Franklin's famous kite experiment.^[4]^[10] The structure has appeared in films like Rocky (1976) and Philadelphia (1993), symbolizing the city's skyline and cultural identity.^[1] Ongoing rehabilitation efforts, including suspension cable inspections and anchorage reinforcements, ensure its structural integrity for future generations.^[11]^[12]

Overview

Location and Connections

The Benjamin Franklin Bridge connects the city of Philadelphia in Pennsylvania to the city of Camden in New Jersey, serving as a vital link across the Delaware River in the Delaware Valley region.^[1]^[13] On the Philadelphia side, the bridge's eastern terminus is located in the Old City neighborhood, adjacent to the Penn's Landing waterfront area along the Delaware River.^[14] In Camden, the western approach lands near the city's downtown waterfront, facilitating direct access to local urban and industrial zones.^[15] The bridge carries Interstate 676 (I-676) and U.S. Route 30 (US 30) on its upper deck, providing a major east-west corridor for vehicular traffic.^[1]^[13] In Philadelphia, it integrates with the Benjamin Franklin Parkway, a prominent urban boulevard that extends westward toward the city's cultural district, while also crossing over I-95 near the riverfront.^[1] On the New Jersey side, I-676 continues into Camden, connecting to regional routes such as New Jersey Route 168, which provides access to I-295 and, further south, the New Jersey Turnpike.^[15] These linkages tie the bridge into the broader interstate network, including I-76 to the west in Philadelphia.^[1] As a primary crossing in the Philadelphia-Camden metropolitan area, the Benjamin Franklin Bridge plays a crucial role in supporting interstate travel and daily commutes between Pennsylvania and New Jersey, bridging the economic and residential hubs of the two states.^[1]^[15]

Significance and Usage Statistics

The Benjamin Franklin Bridge handles approximately 34.1 million vehicle crossings annually as of 2024, positioning it among the busiest bridges in the United States for vehicular traffic.^[1] This high volume underscores its critical role in regional transportation, serving as a primary conduit for daily commuters and commercial vehicles between Pennsylvania and New Jersey. Economically, the bridge is vital for commerce linking Philadelphia and South Jersey, facilitating the movement of goods and supporting employment in sectors such as logistics, tourism, and urban development across the Delaware Valley.^[1] By enabling efficient cross-state connectivity, it bolsters economic integration and growth in the binational region, where daily exchanges of workers and freight drive local industries. Symbolically, the bridge stands as an iconic element of Philadelphia's skyline, frequently appearing in media productions like the films Rocky and Philadelphia, and illuminated with decorative lighting for holidays and special events to celebrate its cultural prominence.^[1] As a key route for state-line commuters, the bridge sees pronounced peak-hour congestion, with traffic patterns shifting to allocate more lanes westward into Pennsylvania during morning rushes, often resulting in delays for tens of thousands of daily users navigating the I-676 corridor.^[16] This commuter reliance highlights its centrality to workforce mobility in the Greater Philadelphia area. The bridge's substantial traffic volume also contributes to regional air quality challenges, as congested roadways in the area exacerbate emissions and pollution in urban corridors.^[17]

Physical Structure and Design

Engineering Features

The Benjamin Franklin Bridge employs a classic suspension bridge configuration, in which two main cables are suspended between a pair of towers and anchored at each end, with vertical suspenders connecting the cables to the roadway deck below. This design efficiently distributes the weight of the 1,750-foot main span across the suspenders, allowing the deck to hang in a stable parabolic curve under load.^[1]^[18] The towers rise 382 feet above the water and are fabricated from riveted steel frameworks, each weighing approximately 10,000 tons, with foundations sunk via caissons into the underlying bedrock to ensure stability against river currents and lateral forces.^[1]^[4]^[19] The main cables, each measuring 30 inches in diameter and comprising 18,666 individual high-tensile steel wires bundled into 61 strands, provide an ultimate strength of 125,000 tons combined; to combat corrosion, a modern dehumidification system—pumping dry air through the cable interiors—was installed during a rehabilitation project starting in 2020 and completed in 2025.^[4]^[20]^[12]^[21] The roadway deck utilizes a steel orthotropic design on the upper level, where the thin steel plate integrates with longitudinal ribs and transverse floorbeams to optimize stiffness and weight reduction for supporting seven vehicular lanes and the PATCO rail tracks in the median; the original deck was replaced with this orthotropic design in the 1980s to address deterioration.^[22]^[23]^[18] The lower level, provisioned in the original 1926 design for additional rail service, has never been utilized and remains vacant. Stiffening trusses along the sides enhance rigidity against torsional forces. Engineered for the challenging environmental conditions of the Delaware River, the bridge incorporates aerodynamic shaping and deep stiffening trusses to resist high winds, which historically caused noticeable sway, while its flexible suspension allows controlled deflection; seismic considerations address minor East Coast earthquakes through the inherent ductility of the steel components and later additions like isolation bearings at expansion joints.^[24]^[25] Upon completion in 1926, it featured one of the world's longest suspension spans and advanced riveted steel fabrication techniques that minimized on-site welding risks.^[18]^[1]

Dimensions and Materials

The Benjamin Franklin Bridge has a total length of 9,650 feet, including approaches, with a main suspension span of 1,750 feet between the towers and side spans of 717 feet each.^[4] The overall width of the structure measures 128 feet, accommodating seven vehicular lanes (curb-to-curb width of approximately 78 feet), two PATCO rail tracks, and two pedestrian sidewalks.^[1]^[26] The bridge features two steel towers, each with four legs and rising 382 feet in height, positioned 135 feet above the Delaware River to allow for navigational clearance.^[1] The anchorages, which secure the main suspension cables, incorporate approximately 216,000 cubic yards of masonry and concrete collectively, supporting the immense tensile forces of the cables.^[4] Approaches to the bridge utilize additional concrete foundations and structures for stability. Construction utilized 70,851 tons of structural steel for the original superstructure, with the steel components riveted together for durability.^[1] The main suspension cables, each 30 inches in diameter, consist of 61 strands containing 306 steel wires per strand, totaling 18,666 wires per cable.^[4]^[7] Concrete is prominently used in the anchorages and approach piers, with caisson foundations for the main towers sunk to depths of up to 40 feet below the riverbed.^[4] The bridge includes two elevated pedestrian walkways, one on the north side and one on the south side, each originally designed at about 10 feet wide to provide separate access for foot traffic.^[19] In recent years, accessibility improvements have added ADA-compliant ramps to these walkways, including a dedicated bicycle ramp on the south side completed in 2019 to eliminate stairs and enhance usability.^[27]

History

Planning and Early Proposals

The concept of a bridge spanning the Delaware River between Philadelphia, Pennsylvania, and Camden, New Jersey, originated in the early 19th century as a means to supplement and eventually replace ferry services that had long connected the cities. The first documented proposal emerged in 1818, when Delaware Valley residents advocated for a low-level structure accommodating sailing ships and horse-drawn vehicles, though it faced opposition from ferry operators and shipping interests concerned about navigation impediments.^[28] Interest waned but resurfaced periodically throughout the 19th century, including a 1851 plan by Philadelphia engineer John C. Trautwine for a four-span suspension bridge with 1,000-foot spans, and a 1868 joint engineering report recommending a low-level crossing incorporating drawbridges to allow passage for river traffic.^[18] These ideas gained renewed momentum following the completion of the Brooklyn Bridge in 1883, whose innovative suspension design over a wide waterway demonstrated the viability of such structures for urban connectivity and inspired engineers to revisit long-span options for the Delaware.^[18] By the early 20th century, the rise of automobiles intensified calls for a fixed crossing, prompting Philadelphia to establish the Penn Memorial Bridge Committee in 1913 to evaluate feasibility amid growing traffic demands.^[29] In 1916, New Jersey Governor James F. Fielder created the Delaware River and Tunnel Commission, which partnered with Philadelphia on a joint feasibility study to assess bridge and tunnel alternatives.^[28] This collaboration culminated in 1919, when the legislatures of Pennsylvania and New Jersey enacted uniform laws forming the Delaware River Bridge Joint Commission, a bi-state body tasked with overseeing planning, site evaluation, and construction coordination.^[19] The commission's first meeting occurred on December 12, 1919, under the chairmanship of Pennsylvania Governor William C. Sproul.^[28] Site selection proved contentious, with the commission and its appointed Board of Engineers conducting extensive surveys to balance engineering challenges, urban alignment, and navigational needs. The chosen location, directly linking Philadelphia's street grid at Chestnut Street to Camden's developing waterfront, was favored for its straight-line approach and minimal disruption to existing infrastructure; alternative upstream or downstream sites were rejected primarily due to stronger tidal currents that posed risks to structural stability and maritime traffic.^[18] Funding discussions highlighted tensions between public and private financing models, with initial explorations of public-private partnerships giving way to a state-led approach supported by toll revenues, as the project represented one of the era's largest public toll initiatives at an estimated cost of $29 million—split between New Jersey ($12.5 million) and a combination of Pennsylvania and Philadelphia ($16.5 million total).^[18] Federal endorsement came in 1921 when President Warren G. Harding signed legislation authorizing the bridge, paving the way for interstate commerce integration.^[28] In one of its initial actions, the Joint Commission appointed a Board of Engineers in 1920, naming Polish-American civil engineer Ralph Modjeski as chief engineer to lead the overall project and ensure coordination across disciplines.^[3] Modjeski, renowned for his work on major U.S. bridges, collaborated with Leon S. Moisseiff as consulting design engineer, who applied his expertise in suspension bridge aerodynamics and deflection theory—honed on projects like the Manhattan Bridge—to optimize the structure for the Delaware's environmental conditions.^[18] The board's recommendations, submitted on June 9, 1921, and approved shortly thereafter, finalized the suspension bridge design and propelled the project forward.^[18]

Construction and Opening

Construction of the Benjamin Franklin Bridge, originally known as the Delaware River Bridge, commenced with a groundbreaking ceremony on January 6, 1922, presided over by Pennsylvania Governor William C. Sproul and New Jersey Governor Edward I. Edwards.^[28] The project was led by chief engineer Ralph Modjeski and design engineer Leon S. Moisseiff, who oversaw the erection of the bridge's signature steel towers, which reached completion by mid-1924.^[28]^[30] The main suspension cables were then spun and installed throughout 1925, marking a critical milestone in the four-year build process that employed thousands of workers.^[31] Foundations for the towers utilized compressed-air caissons sunk into the riverbed to reach bedrock, a technique essential for stability in the Delaware River's challenging underwater conditions.^[32] The construction effort involved significant coordination across state lines, with funding provided by Pennsylvania, New Jersey, and the cities of Philadelphia and Camden through public bonds and appropriations totaling approximately $37 million.^[33] This amount covered the fabrication and assembly of over 70,000 tons of steel, sourced amid lingering post-World War I supply constraints that affected large-scale infrastructure projects of the era.^[1] Labor was organized through unions, ensuring standardized wages and safety protocols for the workforce, though the demanding conditions led to the tragic loss of 14 lives during the build.^[7] Despite occasional setbacks from the river's strong currents during foundation work, the project adhered closely to its schedule, reflecting Modjeski's meticulous oversight. The bridge opened to pedestrian traffic on July 1, 1926, and to vehicular traffic on July 4, 1926, following dedication ceremonies attended by over 25,000 people and presided over by Pennsylvania Governor Gifford Pinchot and New Jersey Governor A. Harry Moore; President Calvin Coolidge delivered the official dedication on July 5 via radio address.^[28]^[34] Initially limited to road and foot traffic, the structure included provisions for future rail integration, which was not implemented until later decades.^[4] At its debut, the span measured nearly two miles in length and stood as the world's longest suspension bridge, facilitating immediate cross-river connectivity for commuters between Philadelphia and Camden.^[35]

Postwar and Modern Developments

Following the bridge's opening in 1926, the lower deck was converted for rail use and opened to transit service on June 7, 1936, accommodating trains operated by the Philadelphia Transportation Company under a lease agreement costing $8.2 million.^[36] In 1955, the bridge was renamed the Benjamin Franklin Bridge to honor the Philadelphia-born Founding Father. In the 1970s, the bridge received its Interstate designation as part of I-676, reflecting broader integration into the national highway system as approaches were completed on both sides.^[37] In response to heightened national security concerns after the September 11, 2001 attacks, the Delaware River Port Authority (DRPA) enhanced bridge oversight, including the launch of a $200,000 patrol vessel on May 9, 2006, funded by federal Homeland Security grants to support river patrols and regional protection.^[28] During the Occupy Philadelphia movement in November 2011, a few hundred protesters marched across the bridge—also known as the Market Street Bridge—to demonstrate against economic inequality as part of nationwide actions.^[38] The DRPA announced plans in 2025 to celebrate the bridge's 100th anniversary on July 1, 2026, highlighting its role in connecting Philadelphia and Camden while carrying over 34 million vehicles annually.^[21] In recent years, maintenance has periodically affected pedestrian access; for instance, the south walkway closed in February 2023 for construction related to bridge preservation (suspender rope replacement), with pedestrians detoured to the north walkway through 2024; both walkways reopened by mid-2024.^[39] Similarly, the bridge fully closed to vehicular traffic on November 2, 2025, from 7:30 a.m. to 10:00 a.m. to accommodate the Larc Run charity event.^[40]

Transportation Uses

Vehicular Traffic

The Benjamin Franklin Bridge accommodates seven vehicular lanes on its upper deck, divided by a movable concrete barrier system that allows for dynamic reconfiguration based on traffic demand. Typically, during weekday peak periods, the configuration provides four lanes for westbound traffic toward Philadelphia and three lanes for eastbound traffic toward Camden, New Jersey, with adjustments made to prioritize the heavier flow direction.^[1] The zipper barrier system, consisting of interlocking concrete segments, was installed in December 2000 to enhance capacity and safety by eliminating the need for a permanently closed lane during rush hours. A specialized barrier transfer machine, known as the "Zipper," operates twice daily—once in the morning to shift lanes westward and again in the evening eastward—moving over a mile of barrier in approximately 25 to 30 minutes using a truck-like vehicle that lifts and repositions the segments. This system reduces congestion by allocating an extra lane to the peak direction, improving overall flow across the 1,750-foot main span.^[28]^[41]^[42] The bridge handles an average of approximately 93,000 vehicles per day, with volumes peaking during morning and evening rush hours when backups often extend several miles onto connecting roadways. These patterns reflect the bridge's role as a vital commuter link between Philadelphia and southern New Jersey, contributing to around 34 million annual crossings.^[1] Direct ramps integrate the bridge with major highways, providing seamless access from Interstate 676 (Vine Street Expressway) in Philadelphia and from Admiral Wilson Boulevard (New Jersey Route 70) in Camden, facilitating high-volume regional travel without at-grade interruptions.^[43]^[44] Safety features include variable message signs installed along the approaches and spans since 2006, which display real-time congestion alerts, travel times, and incident warnings to guide drivers. Inductive loop sensors embedded in the roadway detect traffic volumes and speeds, enabling automated notifications to the Delaware River Port Authority's operations center for proactive management of backups and hazards.^[45]^[46]^[47]

Rail Service

The rail tracks on the Benjamin Franklin Bridge were installed on the lower deck between 1932 and 1936, with the initial Bridge Line service commencing on June 7, 1936, connecting Philadelphia and Camden.^[48] This early rapid transit operation was expanded postwar through integration into the Port Authority Transit Corporation (PATCO) system, which began full service on February 15, 1969, transforming the line into the modern PATCO Speedline.^[49] The PATCO Speedline operates as a 14.2-mile rapid transit route linking 14 stations from Lindenwold in Camden County, New Jersey, to Center City Philadelphia, with the bridge segment spanning the 1.83-mile Delaware River crossing.^[49]^[1] Trains descend from tunnels in Philadelphia, traverse the dedicated lower-deck rails separate from vehicular traffic, and enter tunnels in Camden before continuing at-grade southward.^[50] The system employs third-rail electrification and computer-controlled operations, among the earliest in the United States, with maximum speeds of 65 mph on open segments but limited to 40 mph across the bridge due to its curvature.^[50]^[51] Peak-hour service runs every 3 to 12 minutes on weekdays, supporting approximately 15,300 daily riders as of 2024, the majority of whom utilize the bridge crossing.^[52]^[50]^[49] A major $103 million rehabilitation project replaced the bridge's tracks, signals, power systems, and structures, addressing aging infrastructure to maintain reliability.^[53]

Pedestrian and Bicycle Access

The Benjamin Franklin Bridge provides two parallel elevated walkways for pedestrians and cyclists, located on the north and south sides and separated from vehicular traffic for safety. Each walkway measures approximately 10 feet in width and spans the 1.3-mile distance between Philadelphia and Camden, New Jersey, connecting to local trail networks such as the Circuit Trails system. Access points include 5th and Race Streets in Philadelphia and 4th and Pearl Streets in Camden.^[54]^[27]^[55] The walkways operate daily from 6:00 a.m. to 8:00 p.m. between October 1 and April 30, extending to 9:00 p.m. from May 1 to September 30, though hours may vary due to weather conditions. Bicycles have been permitted on the walkways since their reopening in 1973 following advocacy efforts by cycling groups, with policies requiring cyclists to yield to pedestrians, slow down near stairs, and announce their presence when overtaking. Bicycles are prohibited on the roadway to ensure safety amid heavy vehicular traffic. The annual Ben to the Shore Bike Tour, a charity event starting from the Philadelphia side, draws thousands of participants across the walkways each July, highlighting their role in regional cycling events.^[56]^[55]^[57] Accessibility enhancements include an ADA-compliant ramp completed on the south walkway's Camden side in June 2019, which replaced a 25-foot stairway and improved access for people with disabilities, families with strollers, and cyclists avoiding steps. This $10.5 million project, funded in part by federal and foundation grants, increased overall walkway usage by 63 percent in the following year. The north walkway, however, retains stairs-only access, limiting its usability for some. The walkways attract about 500,000 pedestrian and cyclist crossings annually, serving as a popular route for tourism, exercise, and cross-river commuting.^[58]^[59]^[60] Restrictions apply for safety and maintenance, including closures during high winds, inclement weather, or rehabilitation work; leashed pets are allowed but must be cleaned up after, while skateboards, motorized vehicles, and drones are banned. The south walkway was temporarily closed from February 2023 to May 2024 for bridge repairs, during which users were directed to the north side. As of 2025, the south walkway is closed for upgrades, with users directed to the north walkway.^[55]^[61]^[62]^[55]

Operations and Maintenance

Traffic Management Systems

The Delaware River Port Authority (DRPA) utilizes a Road Zipper system, consisting of a barrier transfer machine and movable concrete barriers, to dynamically reconfigure the bridge's seven vehicular lanes in response to traffic demand, typically shifting the barrier nightly to allocate more lanes toward Philadelphia during morning rush hours and vice versa in the evening.^[42]^[41] The machine, upgraded in 2015, employs sensors to follow embedded magnetic guidance tape in the roadway, enabling precise repositioning of over a mile of barrier at speeds up to 10 mph and completing adjustments in approximately 30 minutes across the bridge's span.^[63]^[64] This setup prevents cross-over and head-on collisions by maintaining physical separation between opposing traffic flows, thereby enhancing overall safety on the structure.^[64] Surveillance on the Benjamin Franklin Bridge includes dozens of closed-circuit television cameras installed since 2008 for real-time monitoring of traffic conditions and security, supplemented by automated license plate readers planned for installation in 2024 to capture vehicle data.^[65]^[66] These technologies feed into the DRPA's Traffic Management Center, which coordinates with regional operations centers such as those operated by PennDOT and the Delaware Valley Regional Planning Commission to provide comprehensive oversight and incident detection.^[67]^[68] Emergency protocols for the bridge encompass detailed evacuation procedures for scenarios including fires, structural alerts, or major incidents, with the DRPA Police Department leading responses that involve ramp closures, escorting of cleanup and medical crews, and interagency coordination with local fire, EMS, and Philadelphia's Office of Emergency Management.^[69]^[70] The bridge serves as a designated pedestrian-only evacuation route in broader regional plans, ensuring safe clearance of vehicles and transit users during hazards.^[60] To address congestion, the DRPA implements variable speed limits displayed via electronic message signs along the bridge and its approaches, a feature enhanced in the 2010s to adjust advisories based on real-time conditions, while ramp metering on connecting highways like I-676 regulates inbound vehicle flow during peak periods.^[46]^[71] These measures integrate traffic data from sensors and cameras to promote smoother flow, with the zipper system further supporting reversibility of lanes for high-demand directions.^[64] Post-2020 upgrades have incorporated advanced data analytics within the DRPA's operations, leveraging sensor inputs for predictive modeling of traffic patterns to anticipate bottlenecks and optimize response times, though specific AI implementations remain integrated into broader regional systems rather than bridge-exclusive tools.^[68]

Toll Collection and Funding

The Benjamin Franklin Bridge collects tolls exclusively in the westbound direction, from New Jersey to Pennsylvania, a policy implemented across all Delaware River Port Authority (DRPA) bridges in 1992 to facilitate traffic flow toward Philadelphia.^[72] Eastbound travel from Pennsylvania to New Jersey incurs no toll, providing a one-way exemption that supports regional commuting patterns.^[72] As of September 1, 2024, the standard toll for passenger vehicles, SUVs, small trucks, and motorcycles weighing 7,000 pounds or less is $6, marking an increase from $5 that had been in place since 2011.^[72]^[73] Trucks and motorhomes exceeding 7,001 pounds gross vehicle weight rating pay a base rate of $18 plus $9 for each additional axle, while buses pay $9 for the first axle plus $4.50 for each additional one; these rates adjust for vehicle size and weight to reflect infrastructure impacts.^[72] E-ZPass users pay the full rate but qualify for discounts through the DRPA Frequent Bridge Travelers Program, which credits $18 monthly to New Jersey E-ZPass accounts for 18 or more round-trip crossings, and a 50% senior discount for enrolled drivers over 65 using New Jersey E-ZPass.^[73]^[74] Tolls are collected at manned plazas with dedicated cash lanes and E-ZPass-only lanes, accepting cash payments alongside electronic transponders; credit cards and mobile payments are not supported.^[72] High-occupancy vehicle (HOV) incentives, such as discounted lanes, have been discussed in regional planning but remain unimplemented on the bridge.^[72] Tolls on the bridge originated at 25 cents per car upon its opening in 1926, with rates for horse-drawn carriages at 30 cents and riders at 15 cents, designed to recover construction costs estimated at $37 million.^[1] Subsequent increases have occurred periodically to account for inflation, maintenance needs, and capital projects, including rises to 75 cents in 1940, $1 in 1950, $3 in 1980, $4 in 2002, $5 in 2011, and the recent adjustment to $6 in 2024.^[1]^[73] These changes are governed by the DRPA Board, balancing revenue requirements with commuter affordability.^[73] Toll revenues primarily fund the DRPA's operations across its four bridges—the Benjamin Franklin, Walt Whitman, Commodore Barry, and Betsy Ross—including maintenance, safety enhancements, and capital improvements such as deck rehabilitations and cable dehumidification.^[72] In 2024, the Benjamin Franklin Bridge generated approximately $104.8 million in toll revenue, contributing to the authority's total of $345.9 million from all bridges, which supports an annual operating budget exceeding $297 million for bridge upkeep and related infrastructure.^[75] These funds ensure ongoing preservation of the nearly century-old structure without relying on general taxes, with excess allocated to debt service and reserve funds for future projects.^[75]

Rehabilitation Projects

In 2020, the Delaware River Port Authority awarded Skanska USA Civil a $195 million contract for the rehabilitation of the Benjamin Franklin Bridge's suspension spans and anchorages, focusing on enhancing structural integrity and longevity.^[76] The project, valued at $216.9 million upon completion, encompassed the installation of a main cable dehumidification system to prevent moisture ingress and corrosion, along with elastomeric wrapping of the cables, miscellaneous steel repairs to address fatigue and deterioration, repainting of the bridge's steel components for corrosion protection, and widening of the pedestrian walkway to improve safety and accessibility.^[76]^[12] Construction began in February 2020 and was completed in 2025.^[76]^[12] The PATCO Speedline track system spanning the bridge was rehabilitated in a $103 million project completed in 2017.^[1]^[77] The work involved replacing the entire track bed, including 9,000 ties, 6 miles of welded rails, and 33 miles of cable, as well as upgrading signaling and electrical systems to modern standards for improved reliability and safety.^[1]^[53]^[77] Deck resurfacing efforts received renewed focus in 2024, with announcements for a major repaving project under contract BF-64-2025, aimed at restoring the roadway surface and finger joints to extend the bridge's operational life.^[78] Preparatory work in October 2025 included resurfacing approximately 120,000 square feet of roadway to improve ride quality and prepare for comprehensive resurfacing in 2026.^[79] This initiative builds on prior emergency pavement repairs, such as those in 2021 that addressed outer lanes with specialized polymer-modified asphalt.^[80] While seismic retrofits are not explicitly detailed in current announcements, the overall rehabilitation incorporates structural enhancements to withstand environmental stresses, aligning with broader maintenance goals.^[12] Anchorage-related work has been ongoing since the 2010s, targeting dehumidification and repairs to the shore foundations to mitigate corrosion from exposure to the Delaware River's humid conditions.^[20] Initial investigations in the mid-2010s assessed cable conditions and designed moisture-control systems, leading to integrated dehumidification installations within the 2020 Skanska project that actively monitor and dry internal cable environments.^[81]^[76] These efforts, combined with foundation reinforcements, have stabilized the anchorages, preventing further degradation in the bridge's concrete and steel elements.^[12] In 2025, the DRPA initiated the Benjamin Franklin Bridge Masonry Rehabilitation project, estimated to run through 2027, to rehabilitate the century-old masonry components of the structure.^[82] As the bridge approaches its 2026 centennial, preparations include upgrades to enhance celebratory events, notably the 2023 installation of an $8 million LED lighting system along the deck and towers.^[83] This system, featuring programmable color-changing lights from Color Kinetics, allows dynamic displays synchronized with PATCO trains and special occasions, replacing outdated fixtures to improve energy efficiency and visual appeal for the anniversary festivities.^[84]^[21] The enhancements ensure the bridge remains a vibrant landmark while supporting ongoing rehabilitation priorities.^[85]
