Interstate 74

East End
West End
The Iowa-Illinois Memorial Bridge carries Interstate 74 across the Mississippi River. The westbound span was opened in 1935 with two-way traffic. The eastbound span was added by 1959.1 The suspension bridge carried U.S. 6 prior to the designation of I-74, which was added to the span once the freeway approaches were constructed in 1974.2 Tolls were collected at the crossing until January 1, 1970.

Interstate 74, a diagonal (northwest to southeast) freeway, serves the Upper Midwest, Southern Great Lakes and Ohio River Valley area. Beginning in Iowa at a trumpet interchange with I-80 in the Quad Cities, I-74 leads southward between Davenport and Bettendorf to cross the Mississippi River into Moline, Illinois. Turning east along side Interstate 280 at Quad City International Airport (MLI), I-74 meets Interstate 80 again at the Big X, a cloverleaf interchange near Colona. Both routes use off-ramps as mainlines there, with Interstate 74 leading south toward Galesburg.

Once at Galesburg, Interstate 74 turns southeast toward Peoria, where it crosses the Murray Baker Bridge over the Illinois River. Interstate 474 provides a bypass to the south while I-74 serves Downtown Peoria and East Peoria. Just east of the city is the north end of Interstate 155 and the village of Morton. I-155 provides cut off south to I-55 for Springfield and St. Louis while I-74 remains eastward to Normal and Bloomington.

A nearly six mile overlap takes Interstate 74 south along side I-55 around the Bloomington-Normal area. Interstate 39 ties into the area just east of the overlap while Business Loop I-55 lines an old alignment of Historic U.S. 66 through the cities. I-74 branches southeast to Champaign and Urbana while I-55 turns southwest to Lincoln.

Interstates 57 and 74 come together at a full cloverleaf interchange on the northwest side of Champaign. I-57 follows a mostly rural route north toward Kankakee and Chicago and south to Effingham and Mt. Vernon. The route connects drivers along I-74 with adjacent Interstate 72, as it leads west from Champaign to Decatur and Springfield. Interstate 74 otherwise runs across northern reaches of the Champaign-Urbana area and then to Danville and the Indiana state line.

U.S. 136 parallels Interstate 74 east from Danville to Crawfordsville and its eastern terminus in Indianapolis. Within the Hoosier State, I-74 sees long exit less stretches and mostly agricultural scenery outside of the Crossroads of America, the nickname of the capital city.

Within Indianapolis and Marion County, a Unigov system formed in 1970, Interstate 74 joins Interstate 465 to travel across the city. Freeway spurs at both connections with the beltway alluded to a continuation, but any plans to take I-74 through the city were dropped early during the Interstate system development. Additionally the west spur joining I-74 with Crawfordsville Road was removed during Accelerate 465 construction between 2007 and 2012.

Beyond Interstate 465, I-74 resumes in a southeasterly heading to Shelbyville, Greensbury, where U.S. 421 leaves the corridor for Versailles, and Morris. The rural freeway reaches a hilly area at the state line where U.S. 52 overlaps into Harrison, Ohio.

The stretch of Interstate 74 through the Buckeye State is punctuated by forested hills and suburban tracts as the freeway winds eastward toward Cincinnati. A short overlap takes the route along the I-275 beltway by Miamitown and across the Great Miami River ahead of the final push into Cincinnati at Mt. Airy Forest. I-74 concludes at the mix of U.S. 27, U.S. 52, U.S. 127 and Interstate 75 by the South Cumminsville neighborhood and Mill Creek in the city.

Three extant sections of Interstate 74 also exist in North Carolina, but they do not connect directly with the existing I-74 from the Quad Cities to Cincinnati. They are from the Virginia state line along I-77 to Mt. Airy, from I-40 in Winston-Salem south to Ellerbe along I-73 and from east of Laurinburg to south of Lumberton along U.S. 74. Three other segments are signed as Future Interstate 74. They are from Mt. Airy south to Winston-Salem along U.S. 52, the Rockingham bypass and the Laurinburg bypass east to Maxton, both along U.S. 74.

High Priority Corridor

North Carolina’s section of Interstate 74 is part of High Priority Corridor 5: I-73/74 North-South Corridor. Its designation in North Carolina is written into law.

Parallel U.S. Routes

Starting in the Quad Cities area, Interstate 74 follows U.S. 150 southeast to Danville, then follows U.S. 136 the rest of the way into Indianapolis. Southeast of Indianapolis, Interstate 74 at first follows U.S. 421, then U.S. 52 the final distance into Cincinnati.

New Mississippi River Bridge

Illinois and Iowa have joined for the I-74 Corridor Study in the Quad Cities area. Improvements underway include work to expand I-74 throughout the Quad Cities, interchange modifications, and a new Mississippi River bridge. Significant funds for the study were included in the SAFETEA-LU bill, signed into law in August 2005.

After years of delays, partially due to funding, construction on the new basket-handle, true-arch twin bridge for I-74 across the Mississippi River kicked off in 2017. Approach work includes the reconstruction of River Drive in Moline (completed in June 2015) and relocation of streets in Bettendorf (work started in April 2015 and ran through the end of 2016). Construction along U.S. 67 relocated the northbound route to run in tandem with southbound on Grant Street as the State Street alignment was severed by new bridge construction. Kimberly Road, the former alignment of U.S. 6, was also redesigned in 2016 to accommodate a new interchange for the span. Total cost for the project is $1.2-billion.3,4

The new Mississippi River bridge will be located just east of the existing Iowa-Illinois Memorial Bridge. Consisting of two four-lane spans with full shoulders, the new crossing will include a multi-use path and scenic overlook at midspan. Preliminary construction on the project started in 2016, with work involving the bridge framework beginning in summer 2017. Partial closures of Interstate 74 west will take place in 2019 as the freeway is redirected to the new bridge. The new westbound span is slated to open by November or December of that year.4

Work scheduled for 2020 effects the eastbound direction of Interstate 74, with partial closures as crews reconfigure the route to tie into the new span. Two-way traffic will use the new westbound span until the Illinois-bound bridge opens by November or December. The old bridge will also remain in use through 2020 to serve local traffic. It will be demolished in 2021.4

Major Projects

Interstate 74 through southwestern Ohio was completed in 1974. The easternmost stretch is undergoing redesign as part of the I-75 Mill Creek Expressway mega project. $13.1 million in construction was completed at the Colerain Avenue and Beekman Street (U.S. 27) interchange from May to September 2012. Additional work, including building a new westbound ramp from I-75 north, started in March 2015. New flyovers will be built on the north side of the exchange with I-75 as well and the Interstate 74 mainline will be rebuilt from Beekman Street east to the viaduct over Mill Creek and the adjacent railroad lines. See the Middle South Board layout for the final design. Construction runs through 2020.

Interstate 74 through Peoria was reconstructed to modern standards between 2002 and fall 2007. The $500 million work affected 11 miles of roads. Photo taken 05/27/08.
Quad Cities – 1972

Construction of Interstate 74 northward from I-280 to the Iowa-Illinois Memorial Bridge replaced the route of U.S. 6 & 150 along 19th-27th Streets north to Downtown Moline. U.S. 6 was later shifted to the freeway northward to Kimberly Road while U.S. 150 was truncated southward from Moline to its intersection with U.S. 6 east of Quad City International Airport (MLI) in 1977.

Peoria – 1960

Costing $15.5 million, the Illini Expressway opened in conjunction with the Murray Baker Bridge on December 12, 1958. The freeway from Glendale Avenue in Peoria to Main Street in East Peoria was considered a local crosstown route when it opened. A six month closure of Knoxville Avenue followed in 1959, with I-74 extended east to Washington Street in East Peoria in 1961 and west to University Street in Peoria in 1963.12

Central Indiana – 1960

The earliest sections of Interstate 74 opened to traffic across the Hoosier State included a bypass of U.S. 136 south of Covington and upgrades to U.S. 421 from southeast of Indianapolis to Shelbyville.

Cincinnati inset – 1961 Ohio Official Highway Map

The Mill Creek Expressway for Interstate 75 was already open to traffic from U.S. 27 and the future east end of I-74 northward in 1961. Maps showed I-74 and I-75 overlapped south into Downtown. This may have been planned, as maps for Cleveland also showed I-71 & 77 concurrent to the Lake Erie waterfront.


The Preliminary Interstate Route Numbering Plan for Illinois released by AASHO on August 14, 1957 routed Interstates 74 and 80 in tandem from Moline southeast to Colona. The Illinois Division of Highways submitted an Urban Numbering Plan to AASHO on July 24, 1958. It assigned Interstate 274 to the Quad Cities East Loop and Interstate 280 to the Quad Cities Southwest Loop. Adjustments were made by November 10, 1958 with the Interstate System Route Numbering approved by AASHO. I-80 replaced I-274 while I-74 and I-280 remained in place through the Quad Cities5

Within Iowa, Interstate 74 opened from north to south:2

  1. August 30, 1968 – from Interstate 80 south to U.S. 6
  2. September 2, 1971 – U.S. 6 south to Kimberly Road
  3. November 26, 1974 – Kimberly Road south to the Mississippi River bridges

Within Illinois, Interstate 74 was completed initially through Peoria along the Illini Expressway and Murray Baker Bridge in December 1958. The cross-state route was finished in 1971 with the opening of I-74 between Bloomington and Mahomet.6,7 See the AARoads guide for Interstate 74 Illinois for more details on the original construction of the freeway.

Representing the first portion of Interstate 74 open to traffic anywhere, the 3,114 foot long Murray Baker Bridge cost $5.5 million to construct when it opened on December 12, 1958. It was named after the businessman that lured Holt Caterpillar Company to East Peoria and R.G. LeTourneau Company to Peoria. The freeway from Glendale Avenue in Peoria to Caterpillar Trail in East Peoria was unofficially named the Illini Expressway. I-74 was finished across the Peoria area and west to Kickapoo in 1965. 1,6 million cubic yards of dirt were removed from Fondulac Hill in East Peoria while 300 homes, 20 apartment buildings and 70 businesses were demolished to make way for the freeway.8,9

The Big X cloverleaf interchange where Interstates 74 and 80 bump one another utilizes a TOTSO (turn off to stay on) movement for both freeway mainlines. In an effort to correct this design issue, Illinois officials proposed renumbering the Quad Cities Interstate system in 1991 to reroute I-80 south over I-280 around Moline and Rock Island and I-74 north over current I-80 from East Moline to Le Claire and north Davenport. The existing I-74 between Moline and Bettendorf would be renumbered as Interstate 174. This action was not supported by Iowa officials and officially dropped in 1993.

Through Peoria and East Peoria, the Upgrade 74 project between October 2002 and December 2006 rebuilt the freeway to modern standards. The $490-million project10 expanded I-74 to six and eight lanes, improved all Peoria interchanges, and rebuilt the approaches to the Murray Baker Bridge. Upgrade 74 work included:7

  • 2003 – Widening Sterling Avenue to six lanes
  • 2003 – Reconstrucing overpasses for Sterling Avenue, Gale Avenue, University Street, Broadway Street, Sheridan Road and Ellis Street.
  • 2003 – Construct a new intersection at Knoxville and Pennsylvania Avenues, reconstruct Downtown Streets and permanently remove the Bigelow Street, Columbia Terrace and Armstrong Street bridges.
  • 2003 – Reconstruct Riverfront Drive and Camp Street ramps in East Peoria
  • 2004 – Construct new ramp tunnels Downtown and ramps for Sterling, Knoxville and Glen Oak Avenues
  • 2004 – Reconstruct over and underpasses for Nebraska Avenue, Perry Avenue, Monroe Street, Madison Street, Jefferson Avenue, Adams Street and Washington Street.
  • 2004 – Reconstruct University Street ramps and eastbound Washington Street ramps in East Peoria.
  • 2005 – Close Murray Maker Bridge and raise Adams Street over I-74 by another 15 feet.
  • 2005 – Widen War Memorial Drive and replace ramps.
  • 2005 – Widen Main Street in East Peoria, reconstruct Washington Street westbound ramps.

Work was to be completed by November 17, 2006, but delays pushed completion to early December 2006. Incidental work involving landscaping and cleanup continued through winter 2007.10

The I-74 and I-155 Improvement Project underway between spring 2013 and fall 2016 rebuilds the freeway and interchange at Morton, Illinois. I-74 was reconstructed and expanded to six lanes from just east of I-474 to Morton Avenue (Exit 102). I-155 was upgraded from I-74 south to Illinois 98 (Birchwood Avenue). The trumpet interchange joining the two freeways was expanded to improve ramp geometry. The single lane tunnels taking Jefferson Street under I-74 were replaced with a conventional overpass while the adjacent abandoned railroad underpass was removed. The interchange with Morton Avenue was also redesigned to eliminate the Exit 102B loop ramp on I-74 eastbound.

Construction on Interstate 74 west of Crawfordsville, Indiana started on January 28, 1964 and was finished on December 7, 1965. Work on the eastern portion in Montgomery County followed two months later, with completion on July 4, 1966. When I-74 was completed across the state in 1967, it was the first interstate within the Hoosier State fully opened.11

Accelerate 465 construction finished in December 2012 rebuilt an 11-mile corridor of the Indianapolis beltway along the west side of the city. The $423 million project included a redesign of the full cloverleaf interchange joining Interstates 74 and 465 with Crawfordsville Road (former U.S. 136). The direct connection from I-74 to Crawfordsville Road was removed and replaced with new ramps joining it and the beltway with U.S. 136 just to the south. This eliminated weaving traffic patterns and the TOTSO connection for the Interstate 74 westbound mainline.

Future Plans

Long range plans called for Interstate 74 to continue east and south of Cincinnati through West Virginia and Virginia into North Carolina and South Carolina, with the freeway ending in Myrtle Beach. However, only North Carolina has shown interest or made progress with building I-74. Ohio and West Virginia are unlikely to ever build their proposed portions of the route.

To make the connection between Cincinnati and Huntington, West Virginia, Interstate 74 was proposed to pass through either Ohio or Kentucky. A feasibility study of routing Northern Kentucky Outer Loop Interstate 74 in Kentucky was completed in March 2003, and it revealed that constructing an east-west bypass around Cincinnati to the south via Kentucky might be needed someday, but it was not necessary at the time. Another study at the time considered routing Interstate 74 along the AA Highway rather than Ohio 32.

In West Virginia, Interstate 74 was programmed to follow proposed Interstate 73 along U.S. 52; the two routes would split before entering Virginia, with Interstate 74 merging with Interstate 77 south into North Carolina.

Interstate 74 shields were first erected along a stretch of U.S. 220 freeway south of Asheboro, North Carolina and in 2000 along a stretch between the Virginia State Line and Mt. Airy, North Carolina. See Interstate 74 in North Carolina and High Priority Corridor 5 for more information and photos.

In South Carolina, a failed state resolution previously attempted to designate the Carolina Bays Parkway as part of Interstate 74, the Veterans Highway/Conway Bypass as part of Interstate 73, and the North Myrtle Beach Connector from Main Street to the parkway as part of a new route called Interstate 174.

The route of I-74 now is proposed to hook southwest from Wilmington, North Carolina to reach the Grand Strand via the Carolina Bays Parkway. I-73 may be built as a toll road but funding has continually remained an issue. The North Myrtle Beach Connector was completed as an at-grade expressway and opened in September 2009.

West End I-80 – Bettendorf, Iowa

Perspective from Interstate 74 west
Interstate 74 runs north between an apartment complex and the Lakehurst subdivision just north of 53rd Street. The final confirming shield for I-74 west stands along this stretch. Photo taken 05/26/18.
A half mile guide sign for Interstate 80 was added to I-74 west ahead of Veterans Memorial Parkway following construction to expand the 53rd Street interchange (Exit 1). The ramps for I-80 are unnumbered. Photo taken 05/26/18.
The original 67th Street overpass was replaced in 2015-16 as part of Bettendorf and Davenport city project to extend Veterans Memorial Parkway east to Utica Ridge Road. Overheads for the ramp separation to I-80 were carbon copied from the previous set of signs. Photo taken 05/26/18.
The westbound lanes of Interstate 74 default onto I-80 west ahead of the cloverleaf interchange with U.S. 61 north and U.S. 61 Business (Brady Street) south. U.S. 61 links the Quad Cities with Dubuque while Interstate 80 ventures west along a busy trucking corridor to Iowa City and Des Moines. Photo taken 05/26/18.
Historic Perspective from Interstate 74 west
Construction from 2010 to November 2012 expanded the diamond interchange at 53rd Street with loop ramps to Interstate 74. The new ramp joining I-74 westbound took the place of this guide sign posted one mile south of the terminus at Interstate 80. Photo taken 09/04/05.
Signs for the upcoming separation of traffic for Interstate 80 were attached to the original 67th Street overpass. This bridge was replaced in 2015 with the development of Veterans Memorial Parkway east from U.S. 61 Business (Brady Street) to Utica Ridge Road. Photo taken 09/04/05.
Perspective from Interstate 80 east
Interstate 80 continues two miles east from the split with U.S. 61 north to meet Interstate 74 at a trumpet interchange (Exit 298). I-74 leads south to the Riverfront of both Davenport and Riverfront while I-80 stays to the north to Le Claire and Rapids City, Illinois. Photo taken 06/19/15.
Yellow placards referencing Local Traffic were added to Exit 298 signs during the mid 2000s to redirect through traffic away from the Iowa Illinois Memorial Bridge. Expansion of the Mississippi River crossing to eight lanes by 2020 should alleviate these concerns. Photo taken 06/19/15.
The rural junction between Interstates 74 and 80 at Exit 298 was targeted for area development, leading to construction of the Rhythm City Casino complex just to the southwest. Interstate 74 travels a short distance south to 53rd Street, which serves a busy retail corridor on parallel Elmore Avenue north toward the casino and south to U.S. 6 (Kimberly Road). Photo taken 05/26/18.
