Interstate 77
Interstate 77 (I-77) is a major north–south Interstate Highway in the eastern United States that extends approximately 611 miles (983 km) from its southern terminus at the interchange with Interstate 26 in Cayce, South Carolina, to its northern terminus at the junction of Interstate 90 and Interstate 480 in Cleveland, Ohio.[1] The route traverses South Carolina, North Carolina, Virginia, West Virginia, and Ohio, providing a key transportation corridor connecting the southeastern region with the Midwest. In South Carolina, I-77 covers about 91 miles (146 km), beginning in the Columbia metropolitan area and heading north toward the North Carolina state line, serving as an important link for regional commerce and travel.[2] Through North Carolina, the highway spans roughly 106 miles (171 km), passing through the major city of Charlotte and facilitating heavy commuter and freight traffic in the Piedmont region.[3] In Virginia, I-77 measures approximately 68 miles (109 km), crossing the Appalachian Mountains via the Big Walker Mountain Tunnel and East River Mountain Tunnel, which are notable engineering features completed in the 1970s to navigate rugged terrain.[4][5] The longest segment of I-77 lies in West Virginia, where it extends 187 miles (301 km), including the 88-mile tolled West Virginia Turnpike between Princeton and Charleston, a four-lane divided highway designated as part of the National Network for freight transport.[6][3] In Ohio, the route covers about 162 miles (261 km), entering from West Virginia at Marietta and proceeding north through Canton and Akron before reaching Cleveland, supporting industrial and urban connectivity in the state's northeastern corridor.[1] Overall, I-77 plays a critical role in interstate commerce, with significant portions designated as part of the National Highway Freight Network to accommodate truck traffic between ports, manufacturing hubs, and consumer markets.[7]Route description

North Carolina
Interstate 77 enters North Carolina from South Carolina at mile 0.00 near Fort Mill and proceeds northward for 105.7 miles (170.1 km) through urban, suburban, and rural areas before crossing into Virginia near Mount Airy. The route serves as a major north-south corridor, connecting the Charlotte metropolitan area with the Piedmont Triad region and the Virginia border, carrying significant commuter and freight traffic. In the Charlotte area, I-77 features high-density interchanges and a segment of managed express lanes from exits 9B to 28 to alleviate congestion.[8] The highway has approximately 42 numbered exits, with mileposts increasing from the South Carolina state line. Exit numbers are sequential and mileage-based, with some gaps in rural sections. The table below details all exits, including mainline and express lane ramps where applicable, destinations, mileposts, and notes on interchange types, such as partial cloverleafs in the Charlotte urban area or concurrencies like I-485 (exits 19A to 20). Express lanes, operational since 2019, provide tolled access for high-occupancy vehicles and single occupants, with dedicated entry and exit points between exits 9B (I-277) and 28 (Catawba Avenue); these lanes include direct ramps and transfer areas for merging with general-purpose lanes. Northern rural areas feature sparser interchanges, such as exit 73 for US 421 in Yadkin County.| Exit | Milepost | Destinations | Notes |

Virginia
Interstate 77 enters Virginia from North Carolina at mile 0.00 in Carroll County and travels north for 67.70 miles through rural, mountainous terrain to the West Virginia border in Bland County. The route features 14 numbered interchanges, with additional shared exits during its 5-mile overlap with Interstate 81 in Wythe County. The segment is characterized by steep grades and curves in the Appalachian Mountains, including approaches to the Big Walker Mountain Tunnel near mile 48, where truck climbing lanes are provided to accommodate heavy vehicles.[11][4] The overlap with I-81 begins at a trumpet interchange near Fort Chiswell (I-77 exit 32 / I-81 exit 70) and ends at another trumpet interchange near Wytheville (I-77 exit 40 / I-81 exit 77), with dual route signing but using I-81's exit numbering for intermediate interchanges. During this section, exits are signed for both routes, including access to VA 16 near Wytheville via local roads. The overlap facilitates connectivity to Roanoke and beyond on I-81, while I-77 continues north through Bland County with rural exits primarily serving county roads and US 52. Truck climbing lanes are indicated on signs in the mountainous areas, particularly between exits 41 and 62, to manage slow-moving commercial traffic on grades up to 6%.[11][12]| Mile | Exit | Destinations | Notes |

Ohio
Interstate 77 enters Ohio from West Virginia at milepost 0.00 via the Marietta/Williamstown Interstate Bridge over the Ohio River, immediately providing access to Marietta in Washington County. The route heads north through predominantly rural terrain in Washington, Noble, and Guernsey counties, intersecting minor state routes that connect to small communities and Amish settlements. As I-77 advances into Tuscarawas and Stark counties around mile 65, it shifts toward more developed areas, serving industrial zones in New Philadelphia, Dover, and Canton with exits to U.S. highways like US 250 and US 30.[25] Nearing mile 120 in Summit County, I-77 reaches the Akron metropolitan area, where it joins the I-76/I-277 innerbelt system—a high-traffic braided interchange complex that facilitates urban circulation and freight movement to manufacturing facilities. Beyond Akron, the highway traverses suburban Summit and Medina counties, crossing the Ohio Turnpike (I-80) at mile 146 and I-271 at mile 144, before entering Cuyahoga County and the Cleveland suburbs. In Cleveland, I-77 follows the elevated Willow Freeway, a series of tight urban ramps providing direct industrial access to steel mills, warehouses, and the port district, with peak congestion often exceeding 100,000 vehicles daily in this corridor. The route ends at milepost 163.28 in a partial cloverleaf interchange with I-90 in downtown Cleveland.[26][25] I-77 in Ohio features 54 mainline exits, numbered sequentially from the southern border, with several auxiliary ramps integrated into the Akron beltway and Cleveland's Willow Freeway. The table below details these exits, including mileposts where documented, primary destinations, and notes on key features such as urban access or traffic volume.| Exit | Milepost | Destinations | Notes |

History
Planning and designation
The planning for Interstate 77 (I-77) emerged as part of the broader development of the Dwight D. Eisenhower National System of Interstate and Defense Highways, authorized by the Federal-Aid Highway Act of 1956, which provided federal funding for a 41,000-mile network of controlled-access highways. Initial route proposals, detailed in the U.S. Bureau of Public Roads' 1955 publication known as the Yellow Book, focused on major corridors but omitted a direct north-south route like I-77, instead emphasizing connections such as U.S. Route 21 alignments in some areas. By 1957, I-77 was designated as a key north-south connector linking the Southeast to the Great Lakes region, spanning from the Carolinas northward to Ohio, to enhance interstate commerce and defense mobility.[29][30] The addition of I-77 to the Interstate System on October 18, 1957, represented a late but significant expansion of 2,102 miles to the overall network, driven by advocacy from Midwestern and Appalachian interests seeking better connectivity for industrial and tourism economies. Ohio business leaders, including S. Durward Hoag, owner of the Lafayette Hotel in Marietta and a prominent figure in the Marietta Chamber of Commerce, played a pivotal role in lobbying federal officials in Washington, D.C., alongside Ohio Governor C. William O'Neill and West Virginia Governor Cecil H. Underwood. These advocates argued that the route would replace underutilized older highways and stimulate economic growth in eastern Ohio and West Virginia by linking Cleveland directly to the Carolinas, addressing the absence of such a corridor in earlier plans.[29][30] Route alignments for I-77 were finalized in the late 1950s by the Bureau of Public Roads, selecting a southern terminus at Interstate 20 near Columbia, South Carolina, to serve as an inland hub rather than a direct connection to Interstate 95 along the coast, which had been considered in preliminary Southeast proposals. The northern terminus was set at Interstate 90 in Cleveland, Ohio, providing access to the industrial heartland. These choices prioritized a spine through the Appalachian Mountains, paralleling U.S. Route 21 where feasible, to connect growing urban centers like Charlotte and Charleston while avoiding overly circuitous paths. The Bureau approved the core alignments across South Carolina, North Carolina, Virginia, West Virginia, and Ohio by 1959, establishing a planned total length of 611.13 miles (983.67 km).[30] Further refinements included extensions in North Carolina, where the Bureau of Public Roads granted approval in October 1964 for an additional segment southward from Interstate 85 to U.S. Route 74 near Charlotte, expanding the route's reach into the state's Piedmont region and reinforcing its role as a vital link in the national system. This decision followed a June 1963 request from the North Carolina State Highway Commission, reflecting ongoing federal-state collaboration to adapt the Interstate plan to regional needs. Overall, the designation process underscored the influence of local political and economic pressures in shaping the final footprint of I-77.[31]Construction phases
Construction of Interstate 77 spanned several decades, primarily during the 1960s and 1970s, as part of the broader Interstate Highway System funded by the Federal-Aid Highway Act of 1956, which allocated federal funds covering 90 percent of costs for qualifying projects nationwide.[32] The total estimated cost for the entire 611-mile route exceeded hundreds of millions of dollars, with significant expenditures on engineering challenges in mountainous regions of Virginia and West Virginia, including extensive rock blasting and tunnel boring to navigate the Appalachian terrain.[4] State departments of transportation coordinated with the Federal Highway Administration to prioritize segments, often building southward from existing highways in Ohio while extending northward from planned connections in South Carolina. In South Carolina, construction commenced in 1962 near Columbia, focusing on the northern extension toward the North Carolina state line to connect with growing urban centers like Rock Hill and Charlotte.[33] A key spur linking to the Charlotte metropolitan area was completed and opened in 1963, facilitating early freight and commuter traffic.[33] The segment from the North Carolina border to I-20 near Columbia, spanning approximately 80 miles, achieved completion in 1987. In 1986, I-77 was extended south from I-20 to its current terminus at I-26 in Cayce, bringing the total state length to 91.2 miles.[33] North Carolina's portions saw initial progress in the Charlotte area during the mid-1960s, with urban segments opening between 1963 and 1967 to integrate with local expressways like I-85.[34] Rural northern sections, traversing the Piedmont and into the foothills, were constructed progressively from 1969 onward, facing delays from terrain and environmental reviews; these opened in phases through the mid-1970s.[35] The final gap near the Virginia border was closed in 1976, completing the state's 105.7-mile alignment, including the challenging 20-mile stretch from Charlotte to Davidson, which opened on New Year's Eve 1975 after prolonged construction delays.[34] Virginia's mountainous construction began in 1965, emphasizing cuts and bridges through the Blue Ridge, with major engineering focused on the Big Walker Mountain Tunnel.[4] Boring for the 4,229-foot tunnel started in 1968 and concluded in 1972 after five years of intensive work involving blasting over 1.5 million tons of rock, opening at a cost of $50 million as the state's first interstate tunnel.[4] The entire 72-mile route from the North Carolina line to West Virginia reached full operability by 1974, incorporating adjacent roadways and overcoming steep grades through innovative alignment designs.[4] In West Virginia, much of I-77 utilized the pre-existing West Virginia Turnpike, originally opened as a two-lane toll road in 1954, which required upgrades to four-lane interstate standards starting in the late 1960s.[6] The 12-mile concurrency with I-64 through Charleston opened in 1968, enhancing connectivity for the capital region's traffic.[36] Northern extensions toward Ohio were finalized by 1975, while the southern East River Mountain Tunnel—connecting to Virginia—was completed in 1974 following groundbreaking in 1969, at $40 million, after 5 years and 4 months of construction that included boring a 5,412-foot passage through solid rock.[4][19] Ohio's development started earliest in the north, incorporating the existing Willow Freeway between Akron and Cleveland, where construction began in 1962 and the segment opened on January 17, 1966.[37] Southern four-lane builds commenced in 1961 near the West Virginia border, with initial work in the Canton area starting in 1958 and opening shortly thereafter.[38][39] The full 162-mile route to I-90 in Cleveland was substantially complete by 1975, though some rural connections lingered into the early 1980s due to phased funding.[38]Recent developments
In South Carolina, the South Carolina Department of Transportation (SCDOT) initiated widening projects along I-77 in the 2010s to address growing commuter traffic from the Charlotte metropolitan area, particularly near Rock Hill in York County. The SC 160 interchange reconfiguration project, which includes expanding the overpass to accommodate up to ten lanes, began construction in the early 2020s and reached significant milestones by September 2025, with the final phase tying into broader corridor improvements.[40] Additionally, groundbreaking occurred in March 2024 for a new interchange at Exit 85 in Fort Mill, adjacent to Rock Hill, featuring a unique design to enhance access and capacity; this $160 million effort is projected for completion around 2028, though related widening segments near Rock Hill are slated to finish by late 2025 to better handle cross-border flows.[41] In North Carolina, the I-77 Express Lanes project, aimed at alleviating congestion north of Charlotte, was contracted in 2015 through a public-private partnership with I-77 Mobility Partners. Construction commenced in November 2015, and the 26-mile tolled managed lanes opened to traffic in November 2019 after overcoming legal challenges from local opposition groups concerned about toll equity and environmental impacts, which were largely resolved by mid-2018 when the North Carolina Department of Transportation declined to terminate the agreement but proposed operational adjustments.[42][43] In 2025, NCDOT outlined plans for I-77 South Express Lanes, adding tolled managed lanes from I-277 to the South Carolina state line, estimated at $3.2 billion with construction beginning in 2030.[44] Virginia's recent developments on I-77 have focused on structural integrity in mountainous terrain, including rehabilitation of the twin New River bridges in Wythe County during the 2010s, which involved deck resurfacing and joint replacements to extend service life amid heavy truck traffic. Ongoing pavement rehabilitation in Wythe County, particularly around the I-81 interchange, continues as part of safety enhancements to reduce hydroplaning risks on curves, with periodic lane closures reported into 2025.[45][46][47] In West Virginia, upgrades to the I-77 bridges over the Kanawha River near Charleston occurred in the 2000s, incorporating seismic retrofits and scour protection to improve durability against river currents and potential seismic activity. Following the devastating 2016 floods that caused widespread infrastructure damage, state efforts enhanced flood resilience along I-77 corridors through elevated embankments and improved drainage systems in flood-prone areas like the Kanawha Valley, as outlined in the West Virginia Flood Resiliency Plan finalized in 2024.[48][49] Ohio's improvements included the widening of I-77 in Summit County from four to six lanes between I-76 (Ohio Turnpike) and Norton, with construction phases spanning 2015 to 2022 to boost capacity for freight and commuter routes in the Akron area. The $160 million Akron Beltway reconstruction, integrating I-77 with I-76 and SR 8, involved pavement replacement and new flyover bridges, completing in August 2025 after four years of work. In the 2010s, the Cleveland Innerbelt project tied directly to I-77 by widening the bridge over I-490 and reconfiguring ramps, part of a broader $285 million effort to modernize the urban core's infrastructure.[50][51][52] Safety initiatives across the route have included the implementation of variable speed limit systems in the 2020s, notably on I-77's mountainous sections in Virginia to adjust limits dynamically based on visibility and weather, reducing crash rates in low-visibility conditions. Collectively, these recent developments since the 2000s represent investments exceeding $2 billion across the states, encompassing express lanes, widenings, and resilience measures to sustain the highway's role in regional commerce.[53][54]Auxiliary routes
I-277 in North Carolina
Interstate 277 (I-277) in North Carolina is an auxiliary Interstate Highway that functions as a partial beltway around Uptown Charlotte, spanning 4.46 miles (7.18 km) and connecting Interstate 77 (I-77) on the west to Interstate 85 (I-85) on the east. The route forms a "U"-shaped loop that encircles Charlotte's central business district, serving as an inner loop for local and regional traffic accessing the city's core. It is cosigned with U.S. Highway 74 (US 74) along portions of the eastern John Belk Freeway and with North Carolina Highway 16 (NC 16) along the western Brookshire Freeway, facilitating commerce and commuter flows in the Southeast's largest metropolitan area.[55][56] The southern terminus of I-277 joins I-77 at exit 11 near the Brookshire Freeway interchange, while the northern/eastern end ties into I-85 via US 74 southeast of Uptown, providing seamless connectivity for vehicles bypassing the downtown core. This configuration supports the route's role in diverting traffic from the congested I-77 mainline through Charlotte, with key interchanges including those at NC 16 (overlapping the Brookshire Freeway) and the recent integration with the I-77 express lanes extension, which enhances managed lane access for high-occupancy and toll-paying vehicles. Unlike longer outer loops such as I-485, I-277 has no independent spurs or bypasses, relying on its compact design to fully encircle the central business district in tandem with the short I-77 segment closing the loop.[55][57][42] Construction of I-277 was integrated into broader I-77 corridor planning to address urban mobility needs in growing Charlotte. The western leg, known as the Brookshire Freeway, opened in 1970 as the Northwest Expressway, linking Independence Boulevard northward to the planned I-77 alignment and initially designated as part of NC 16. The eastern John Belk Freeway was built in phases, with the segment from Independence Boulevard to Kenilworth Avenue opening in 1981 and the extension southward to I-77 completing in 1988, named in honor of former Charlotte mayor John Belk. Construction of I-277 in the 1970s and 1980s displaced several neighborhoods, including historically Black communities in Brooklyn, as part of urban renewal efforts. The route received AASHTO approval on June 29, 1978, following conditional FHWA approval in 1974, with the full loop signed as I-277 in 1989. Recent developments, including the reconstruction of the I-277/I-77 interchange, part of the $647 million I-77 express lanes project completed in 2020, have improved capacity and safety at this critical junction.[58][55][42]I-277 in Ohio
Interstate 277 (I-277) in Ohio is a 4.35-mile (7.00 km) auxiliary Interstate Highway serving as a short circumferential route in the Greater Akron area, connecting Interstate 77 southeast of the city to Interstate 76 and U.S. Route 224 on the east side. The freeway overlaps with US 224 for its entire length, enabling efficient regional connectivity between north-south and east-west corridors in Summit County.[59][60] This route functions as a partial bypass for downtown Akron, diverting traffic around the urban core and featuring key interchanges with the toll-free portion of I-76 (also known as the Kenmore Leg) and US 224 near the Portage Lakes area.[59] It supports local commuting and commercial travel in the industrial suburbs of Coventry Township and south Akron, integrating with nearby State Route 8 to complete an inner belt system around the city center. No extensions to the route are planned, maintaining its focused role as a compact connector.[61] Planning for I-277 began in the 1960s as an auxiliary to I-77, with an initial proposal in 1965 to align it along US 224 from the I-76 interchange to I-77 near Ohio State Route 619. Construction progressed in phases, with the western leg from I-76 to Waterloo Road opening by 1962, and the full route completed in 1970 as part of broader freeway extensions in the Akron region.[59][62] I-277 facilitates freight movement for the remnants of Akron's rubber industry, historically centered on companies like Goodyear, by linking industrial zones and handling substantial truck traffic through southern Summit County.[63]Exit lists

Interstate 77 enters Virginia from North Carolina at mile 0.00 in Carroll County and travels north for 66.27 miles (106.65 km) through rural, mountainous terrain to the West Virginia border in Bland County. The route features 17 numbered interchanges, with additional shared exits during its 5-mile overlap with Interstate 81 in Wythe County. The segment is characterized by steep grades and curves in the Appalachian Mountains, including approaches to the Big Walker Mountain Tunnel near mile 47, where truck climbing lanes are provided to accommodate heavy vehicles; ventilation upgrades at the tunnel were completed in 2024.[11][4][17] The overlap with I-81 begins at a trumpet interchange near Wytheville (I-77 exit 40 / I-81 exit 72) and ends at another trumpet interchange near Fort Chiswell (I-77 exit 32 / I-81 exit 81), with dual route signing but using I-81's exit numbering for intermediate interchanges. During this section, exits are signed for both routes, including access to VA 16 near Wytheville via local roads. The overlap facilitates connectivity to Roanoke and beyond on I-81, while I-77 continues north through Bland County with rural exits primarily serving county roads and US 52. Truck climbing lanes are indicated on signs in the mountainous areas, particularly between exits 41 and 62, to manage slow-moving commercial traffic on grades up to 6%.[11][12]| Mile | Exit | Destinations | Notes |

West Virginia
Interstate 77 enters West Virginia from Virginia at milepost 0.00 via the East River Mountain Tunnel near Bluefield in Mercer County, marking the start of its 187.21-mile course through the state to the Ohio border at milepost 187.21 near Williamstown in Wood County.[19][20] The route traverses mountainous terrain in the south, including the tolled West Virginia Turnpike from near Princeton (exit 9) to Charleston (exit 96), before transitioning to more level rural landscapes in the north.[6] In the Kanawha Valley, I-77 provides essential access to urban Charleston, concurring with Interstate 64 from exit 85 to exit 101 with dual numbering.[21] The highway features approximately 47 mainline exits, with additional directional ramps and facilities including service plazas near Beckley (exit 45) and weigh stations near Mineral Wells (mile 166).[21] East River Tunnel ramps connect directly to the state line without a numbered exit.[19]| Exit | Destinations | Notes |

Ohio
Interstate 77 enters Ohio from West Virginia at milepost 0.00 via the Marietta/Williamstown Interstate Bridge over the Ohio River, immediately providing access to Marietta in Washington County. The route heads north through predominantly rural terrain in Washington, Noble, and Guernsey counties, intersecting minor state routes that connect to small communities and Amish settlements. As I-77 advances into Tuscarawas and Stark counties around mile 65, it shifts toward more developed areas, serving industrial zones in New Philadelphia, Dover, and Canton with exits to U.S. highways like US 250 and US 30.[25] Nearing mile 120 in Summit County, I-77 reaches the Akron metropolitan area, where it joins the I-76/I-277 innerbelt system—a high-traffic braided interchange complex that facilitates urban circulation and freight movement to manufacturing facilities. Beyond Akron, the highway traverses suburban Summit and Medina counties, crossing the Ohio Turnpike (I-80) at mile 146 and I-271 at mile 144, before entering Cuyahoga County and the Cleveland suburbs. In Cleveland, I-77 follows the elevated Willow Freeway, a series of tight urban ramps providing direct industrial access to steel mills, warehouses, and the port district, with peak congestion often exceeding 100,000 vehicles daily in this corridor. The route ends at milepost 163.03 in a partial cloverleaf interchange with I-90 in downtown Cleveland.[26][25] Note: Widening projects near Akron were ongoing as of 2025. I-77 in Ohio features 54 mainline exits, numbered sequentially from the southern border, with several auxiliary ramps integrated into the Akron beltway and Cleveland's Willow Freeway.
