Interstate 57
Interstate 57 (I-57) is a north–south Interstate Highway in the central United States spanning approximately 496 miles (798 km) from its southern terminus at Interstate 40 (I-40) near North Little Rock, Arkansas, to its northern terminus at Interstate 94 (I-94) in Chicago, Illinois. Its previous southern terminus was at Interstate 55 (I-55) and U.S. Route 60 (US 60) in Sikeston, Missouri.[1][2] The route begins near North Little Rock, covering 110 miles (180 km) through central Arkansas to Walnut Ridge before entering Missouri. In southeastern Missouri, it covers 22 miles (35 km) through rural areas including Charleston and Bertrand before crossing the Mississippi River at Cairo into Illinois.[3] In Illinois, I-57 extends 364 miles (586 km) diagonally northwestward, making it the longest Interstate Highway located entirely within the state, and parallels sections of the historic Illinois Central Railroad.[4] It passes through major cities and regions such as Marion, Mount Vernon, Effingham, Champaign-Urbana, Kankakee, and the southern suburbs of Chicago, serving as a vital corridor for both passenger and freight traffic.[1] In November 2024, a 110-mile (177 km) segment of former U.S. Highway 67 in Arkansas—from I-40 near North Little Rock to US 412 in Walnut Ridge—was officially redesignated as I-57 by the Federal Highway Administration, marking the addition of the highway's first mileage in that state and extending its southern reach as part of a planned 240-mile corridor to connect with the existing route in Missouri.[2] Ongoing projects in southeastern Missouri aim to upgrade U.S. Route 67 from the Arkansas state line to Poplar Bluff and U.S. Route 60 from Poplar Bluff to Sikeston to complete this connection.[5] I-57 intersects ten other Interstate Highways along its path, including I-30 near Jacksonville, Arkansas, I-40 near North Little Rock, I-24 near Marion, I-55 near Sikeston, I-64 near Mount Vernon, I-70 near Effingham, I-72 near Urbana, I-74 near Champaign, I-80 near Joliet, and I-94 in Chicago, facilitating regional connectivity from the Midwest to southern gateways.[1] Designated as a National Highway System corridor, it carries significant truck traffic—averaging over 30% of its vehicle miles traveled—and supports access to multimodal facilities, including rail lines and proximity to Chicago's O'Hare International Airport.[1] The highway is fully divided with four lanes throughout its length, except in urban Chicago where it may include additional lanes or tolled sections like the Illinois Tollway.[1]Route description
Missouri
Interstate 57 enters Missouri from the south at a cloverleaf interchange with I-55 and US 60 near Miner, marking mile marker 0.00 and serving as the southern terminus.[6] The route then heads northeast through rural areas of New Madrid and Mississippi counties, concurrent with US 60 for its entire length in the state, before crossing the Mississippi River into Illinois at mile marker 22.3.[7] There are no auxiliary lanes along this segment.[8] The exits are listed below, with approximate mile markers based on the southern terminus in Miner.| Exit | Mile | Locations | Notes |

Southern Illinois
Interstate 57 enters the state of Illinois from Missouri via the Cairo Mississippi River Bridge, a steel through arch bridge spanning the Mississippi River near Cairo in Alexander County.[9] Completed in 1978, the bridge marks the continuation of the highway's north-south alignment after its brief segment in Missouri.[10] From here, the route proceeds northward through rural landscapes, initially paralleling the Mississippi River before turning inland. The southern segment of I-57 covers approximately 80 miles across Alexander, Pulaski, Massac, and Williamson counties, featuring a mix of flat agricultural lowlands and rolling hills associated with the Illinois Ozarks and the southern foothills of the Shawnee National Forest.[6][1] This terrain reflects the transitional geography of the Mississippi River floodplain giving way to the uplands of southern Illinois, with the highway maintaining a generally straight path amid forested and farmed areas.[11] Key interchanges along this stretch include Exit 1 for Illinois Route 3 and U.S. Route 51 near Cairo, though the city itself lacks a direct exit and is accessed via local roads; Exit 4 for U.S. 51 at Mounds; Exit 31 near Vienna; Exit 37 for Illinois Route 37 serving Metropolis; and multiple exits in Marion, including Exit 54 for Illinois Route 13 and the junction with Interstate 24.[12][13] These connections facilitate travel to nearby communities and provide entry points to the region's natural and economic hubs. As a primary north-south artery, I-57 functions as a bypass for the older U.S. Route 51 corridor, which it parallels closely from Cairo northward, offering improved safety and capacity for traffic serving southern Illinois' coal mining operations and agricultural production.[6][14] The highway supports freight movement and regional connectivity, linking rural counties to larger transport networks without passing through densely urbanized areas.[1]Central Illinois
Interstate 57 traverses central Illinois for approximately 120 miles, passing through Jefferson, Marion, Clay, Fayette, Effingham, Cumberland, Coles, and Douglas counties as it continues northward from the Marion area in southern Illinois.[1] This segment cuts through expansive flat farmlands characteristic of the heartland prairies, supporting extensive agricultural activities and serving as a vital link for regional commerce.[6] The route remains predominantly rural, with occasional small towns and major interstate junctions providing connectivity to east-west corridors.[11] From its entry into central Illinois near Mount Vernon in Jefferson County, I-57 intersects Interstate 64 at a significant junction that facilitates travel between St. Louis and southern Indiana.[6] The highway then proceeds through Marion County, passing Salem with access via U.S. Route 50 and Illinois Route 37 at exit 116, before reaching Effingham in Effingham County—though the route technically enters Effingham County slightly later.[11] At Effingham, I-57 meets Interstate 70 in a major interchange, marking the crossroads that handles substantial cross-country traffic.[1] Beyond Effingham, the freeway continues through Fayette, Cumberland, Coles, and Douglas counties, bypassing Mattoon and providing access to Charleston via Illinois Route 16 at exit 190A.[6] As the primary north-south interstate in central Illinois, I-57 connects agricultural hubs and smaller communities, including university towns like Charleston, home to Eastern Illinois University, which draws students and visitors via key exits.[15] The route experiences high truck volumes, driven by manufacturing facilities in Effingham and the transport of grain and other farm products from surrounding prairies, with average daily traffic exceeding 30,000 vehicles in some segments and truck percentages around 25-30%.[16][1] This freight emphasis underscores I-57's role in supporting the region's economy, though the four-lane divided highway maintains a consistent rural profile throughout.[17]Northern Illinois
Interstate 57 enters northern Illinois as a northward extension from the central region near Effingham, traversing approximately 180 miles through Champaign, Ford, Iroquois, Kankakee, Will, and Cook counties before reaching its northern terminus.[1] In Champaign County, the highway passes through the university-dominated Champaign-Urbana metropolitan area, where a major interchange provides access to Interstate 74 and Illinois Route 47, facilitating connectivity for local traffic and regional travel.[18] Northward, I-57 transitions into more rural landscapes across Ford, Iroquois, and Kankakee counties, serving agricultural communities with interchanges such as the one at Gilman for U.S. Route 24 and in Kankakee for Illinois Route 50, which support freight movement and local commerce along this corridor.[19] As I-57 approaches the Chicago metropolitan area in Will County, it integrates with suburban infrastructure, including a significant interchange at Monee with Interstate 80, which enhances east-west connectivity for trucking and passenger vehicles.[20] Further north, the route briefly parallels and connects to the Tri-State Tollway (I-294) in Cook County, aiding in the distribution of traffic toward western suburbs and providing indirect access to O'Hare International Airport via linked expressways.[20] This segment underscores I-57's role in managing commuter flows into the densely populated Chicago region, where daily volumes support both residential travel from southern suburbs and commercial logistics.[21] The highway culminates at its northern terminus on the south side of Chicago, merging into the Bishop Ford Freeway (Interstate 94) near 127th Street in a complex interchange that handles high volumes of merging traffic.[1] This endpoint positions I-57 as a vital artery for southbound commuters and northbound freight entering the urban core, alleviating pressure on parallel routes like I-55 while integrating with the broader Chicago expressway system.[22]History
Planning and designation
The planning for Interstate 57 originated in the mid-1950s as part of the broader effort to establish the national Interstate Highway System under the Federal-Aid Highway Act of 1956, which authorized the construction of 41,000 miles of limited-access highways across the United States. This legislation provided federal funding at a 90% match to states for building high-speed roads designed for national defense and commerce, with routes selected to connect major population centers and economic corridors. I-57 was specifically envisioned as an upgrade to the existing U.S. Route 51, a key north-south corridor through central Illinois that had long served agricultural and industrial traffic but lacked the capacity and safety standards of modern freeways.[6] By paralleling much of US 51, I-57 aimed to improve connectivity between rural areas and urban hubs without diverting significantly from established travel patterns. On August 14, 1957, the Bureau of Public Roads approved the initial Interstate route designations, including I-57 as a north-south highway linking Interstate 55 near Miner, Missouri, to the Chicago area in Illinois. This designation positioned I-57 to provide a direct alternative to I-55 for traffic heading north from the Gulf Coast region, facilitating a corridor from southern ports to the Great Lakes via connections in Chicago. The route's termini were finalized at approximately 386 miles, starting at the I-55 junction in Miner and ending at the intersection with I-94 (also known as the Dan Ryan Expressway) on Chicago's South Side.[6] Early alignments followed US 51 northward from the Illinois border, but planning emphasized resilience against regional challenges, such as the frequent Mississippi River flooding near Cairo, Illinois, while maintaining access to southern Illinois communities.[4] In November 2024, the Federal Highway Administration officially designated a 110-mile (177 km) segment of former U.S. Highway 67 in Arkansas—from I-40 in North Little Rock to US 412 in Walnut Ridge—as I-57, adding the highway's first mileage in that state and extending its southern reach as part of a planned 240-mile corridor to connect with the existing route in Missouri.[2] Interstate 57 has no official name beyond its numerical designation, consistent with federal policy for most Interstates, though segments in Chicago parallel the Major Taylor Trail, a multi-use path locally recognized for its recreational value and named after the pioneering African American cyclist Marshall "Major" Taylor.[23] This trail, running alongside the highway from the Dan Ryan Woods to Whistler Woods, highlights urban integration efforts but does not alter the Interstate's formal identity.Construction
Construction of Interstate 57 commenced in the late 1950s, implementing the route designations established earlier in the decade through federal interstate planning. The initial paving contract for the southern Illinois portion was awarded in January 1958 to Leon B. Stilley Construction for $1.079 million, marking the start of physical development.[24] The first major segment, spanning 30 miles from Dongola north to Marion in southern Illinois, opened to traffic on September 26, 1961, following dedication by Governor Otto Kerner; this stretch traversed the hilly terrain of the Shawnee National Forest at an estimated cost of $21 million. Subsequent openings in the 1960s advanced the southern phase, including the extension from Marion to Johnston City on November 1, 1962, the West Frankfort interchange in 1963, and completion to Mount Vernon by 1965. Engineering in this region incorporated flood-resistant features, such as elevated structures and drainage systems, to mitigate risks from the Mississippi River floodplain near Cairo, culminating in the Cairo I-57 Bridge—a steel through-arch span opened in 1978 after six years of construction at a cost of $25.4 million.[25][6] Central Illinois segments progressed through the 1970s, with multiple openings in 1969 alone, including 21.5 miles from Mount Vernon to Centralia, 14 miles from Mattoon to Arcola, and bridges over rivers such as the Kaskaskia to accommodate the flat, agricultural landscape. Challenges included acquiring right-of-way through farmlands, which required extensive negotiations and eminent domain proceedings, and minimizing environmental disruption in sensitive wetland areas like the Cache River swamp, where elevated roadways preserved habitat integrity. The northern phase featured urban viaducts in Chicago as part of the Dan Ryan Expressway extension, with segments opening between 1963 and 1970, and the final rural link near Paxton completed in 1971.[4][6] The entire route, including the short Missouri portion from the Mississippi River bridge north to Interstate 55 near Miner, reached full completion on June 23, 1978, with the bridge's opening eliminating the last gap and connecting the 21.77-mile Missouri segment built concurrently in the mid-1970s. Overall, construction emphasized durable designs for flood-prone southern areas and efficient crossings in central farmlands, though environmental concerns in the Shawnee National Forest led to route adjustments to limit habitat fragmentation.[6]Future developments
Ongoing projects
Several ongoing projects along Interstate 57 (I-57) focus on enhancing capacity, safety, and structural integrity, primarily in Illinois under the Rebuild Illinois program. These initiatives address increasing freight traffic and aging infrastructure, with construction activities spanning 2024 through 2028.[26] In southern Illinois, a major widening project is expanding I-57 from four to six lanes between Marion and Mount Vernon, including the replacement of bridges over the Big Muddy River at mileposts 66-75 and over Marcum Branch and Gun Creek at mileposts 75-85. This $325 million effort, which began in phases starting in 2023, involves resurfacing, median barrier installation, and drainage upgrades to improve traffic flow for the corridor's high volume of trucks.[26][27] Further north in Champaign County, the I-57/I-74 interchange reconstruction, initiated in 2021 and continuing through 2025, adds auxiliary lanes, flyover ramps, and shoulders while replacing bridges, including the I-72 over I-57 structure, at an estimated cost of $251.8 million. This project modernizes the outdated cloverleaf design to reduce congestion at a key freight junction, with the new westbound I-74 to southbound I-57 flyover ramp opening on August 27, 2025.[28][29][30] Bridge rehabilitation efforts include ongoing inspections and repairs near the Cairo area. The I-294/I-57 interchange near Chicago was completed in 2022 with new ramps and bridge components to enhance structural resilience.[31] Safety enhancements by the Illinois Department of Transportation (IDOT) include the addition of shoulder and centerline rumble strips along southern segments of I-57 as part of the six-lane expansion, set for completion in 2025 to alert drivers of lane departures. Near Effingham, projects incorporate pavement preservation to mitigate risks from heavy commercial vehicles, aligning with broader interstate safety modernization.[32] Funding for these projects draws from the federal Infrastructure Investment and Jobs Act (IIJA) and the Rebuild Illinois capital plan, which integrate federal support to prioritize high-impact corridors like I-57.[33][34] Environmental mitigations accompany expansions, particularly in the Marion area, where wetland restorations offset impacts from the six-lane project; approximately 4.77 acres of wetlands are being restored through compensatory planting and habitat enhancement to comply with federal regulations. These efforts ensure minimal disruption to local ecosystems during construction.Planned extensions
The primary planned extension for Interstate 57 involves its southward continuation into Arkansas along the alignment of U.S. Route 67, designated as Future I-57 to enhance connectivity within the National Highway System. On November 7, 2024, the Federal Highway Administration officially redesignated approximately 110 miles (177 km) of U.S. 67 from North Little Rock to Walnut Ridge as I-57, marking a significant step in closing the gap between the existing I-57 terminus near Miner, Missouri, and further southern connections. This extension aims to link northeastern Arkansas more directly to the interstate network, supporting freight movement and economic development in the region. In October 2025, construction began to widen a segment of the new I-57 (former US 67/167) to six lanes in Pulaski County.[35] Studies and planning for this corridor, initiated in the early 2020s, have progressed through environmental reviews, with the Federal Highway Administration issuing a Record of Decision on October 24, 2023, approving the preferred alignment from Walnut Ridge to the Missouri state line.[36] In Arkansas, the 42-mile segment from Walnut Ridge to the Missouri border is planned as a four-lane divided highway, with proposed interchanges at County Line Road (Randolph and Lawrence counties), Arkansas Highway 304, Hile Road, Duck Levee Road, Arkansas Highway 67 (west and north of Corning), and State Line Road. Construction on the initial phase, including the 4.1-mile Corning Bypass, is scheduled to begin in 2025 as part of the Connecting Arkansas Program, with an estimated cost of $55 million for that segment alone. The selected route minimizes impacts to properties, farmlands, and streams compared to other alternatives evaluated during the National Environmental Policy Act process. Further phases will extend northward into Missouri, where the Missouri Department of Transportation is upgrading U.S. Route 67 to interstate standards in Butler County, with Phase 3 (from County Road 352 to near County Road 272, including the Neelyville interchange) and Phase 4 (including the State Line Road interchange) planned for award and construction starting in summer 2026, funded primarily through state revenues.[36][37][5] While no direct extension to Interstate 55 further south of its current junction has been proposed in recent studies, the Arkansas and Missouri segments will effectively extend I-57's reach toward the I-55 corridor via existing connections near the Mississippi River. In northern Illinois, long-term improvements focus on enhanced integration rather than linear extensions, with the Chicago Metropolitan Agency for Planning incorporating I-57 reconstruction from I-94 to the Will-Kankakee county line into its ON TO 2050 comprehensive regional plan as a regionally significant project to support multimodal freight corridors and address projected 2050 travel demands. This includes potential new access points in Will County, where an ongoing study initiated in late 2023 evaluates improvements along I-57 from south of Wilmington-Peotone Road to north of Manhattan-Monee Road, emphasizing truck and freight accommodations; the study is expected to conclude in early 2028, potentially leading to new interchanges for economic development.[38][39] Proposed new interchanges along existing alignments include enhancements for economic and freight purposes, such as a potential exit near Illinois Route 133 in Arcola to bolster local development in the I-57 corridor, though detailed studies remain in preliminary stages as of 2025. A freight-oriented bypass around Kankakee has been discussed in regional planning but lacks specific funded proposals beyond general interchange upgrades. Environmental reviews for southern extensions, including those near the Shawnee National Forest in Illinois, have historically addressed impacts for maintenance rather than expansions, with no active extension studies in that area. Budget constraints post-2025 pose challenges, as noted in the Illinois Department of Transportation's FY 2025-2030 plan, which highlights ongoing funding limitations for infrastructure amid competing priorities, potentially delaying unfunded phases of the Arkansas-Missouri corridor.[40]Exit list
