Interstate 474 Illinois

East End
West End


Interstate 474 provides a bypass of Peoria and East Peoria while serving General Wayne A. Downing Peoria International Airport (PIA) and the suburbs of Bellevue, Bartonville, Creve Coeur, Marquette Heights and North Pekin. The freeway ties directly into the Illinois 6 freeway spurring north to Mossville and ends to the east near the north end of I-155 at Morton. I-474 spans the Illinois River across the Shade-Lohmann Bridge, a pair of 3,420 foot plus steel through truss bridges.

Eastern Bypass

Plans for the Eastern Bypass Project, a limited access extension of the IL 6 freeway east across the Illinois River at Mossville and southeast to East Peoria, would complete a full beltway of Peoria in conjunction with Interstate 474. The bridge and remaining freeway miles were initially estimated to cost $800 million. The passage of SAFETEA-LU in 2005 appropriated $2.4 million for design, engineering, and land acquisition for the eventual corridor. A corridor study for the beltway followed.1

Directed by the Illinois Department of Transportation (IDOT), Phase 1 (Corridor Selection and Alignment) of the Eastern Bypass Project narrowed a list of 20 potential corridors to 14 then six. Input from the Community Advisory Group (CAG) subsequently reduced the number to four. Those remaining generally traveled southeast from Mossville along a corridor east of Germantown Hills and west of Washington to varying locations along Interstate 74. The P2 alignment connected with I-74 at I-474, while M-10 and T-6 were further east near Main Street and Tennessee Avenue in Morton, leaving D-13 near Dee-Mack Road toward the village of Deer Creek. The city of Peoria passed a resolution supporting Corridor P2.2 Completion of the ring road with I-474 and Illinois 6 remains a regional priority as of 2015.3

A proposed “Peoria to Chicago” expressway is also under consideration, with three corridors outlined in 1996. The corridor would branch north or northeast from Illinois 6 / Eastern Bypass to connect Peoria with Interstates 39, 55 or 80. One route involved an upgrade of the Illinois 29 corridor northward from Mossville to I-180 while another paralleled Illinois 116 east to I-55 at Pontiac.4,5

Construction of Interstate 474 across the Illinois River – 1971 Illinois Official Highway Map
The Shade-Lohmann Bridge opened as a local link between U.S. 24 and IL 29 in 1978. The remainder of the freeway opened the following year.


Construction for Interstate 474 was underway by the early 1970s, but stopped in 1973 due to the need for an environmental impact statement. Completed at the time was the Shade-Lohmann Bridge spanning the Illinois River. Work on the freeway resumed in 1976, with a 3.6 mile stretch from U.S. 24 (McKinley Street) at Bartonville and south Peoria to Illinois 29 at Creve Coeur opened two years later. A dedication ceremony on August 30, 1978 opened the freeway and formally named the bridge in honor of former Pekin legislators J. Norman Shade and Martin Lohmann.6

Lohmann retired in 1952 after a 30 year career with terms in both the state House and Senate. Shade started his political career in 1908 and served in office for 40 years with terms as a state representative, Tazewell County Board and mayor of Pekin. He was a proponent for the 1930-opened Pekin Bridge (IL 9) and for the construction of IL 121 (I-155). The blue paint scheme for their bridge was selected from a 1973 contest conducted by IDOT.6,7

The remainder of Interstate 474 north to Illinois 6 and east to I-74 at East Peoria opened to traffic on December 20, 1979. Illinois 6 extended the Peoria ring road north from I-74 / 474 to U.S. 150 on December 20, 1979, from U.S. 150 north to Illinois 40 (former IL 88) on December 28, 1982 and from Illinois 40 north to Illinois 29 on November 3, 1985.8

U.S. 24 was relocated from a route through Downtown Peoria along Adams and Washington Streets to overlap with Interstate 474 between Exits 6 and 9 by 2013. The reroute was the result of Peoria City Council actions to take over maintenance of Washington Street. While promoting development in the Warehouse District, the city planned on allowing on-street parking on both sides of the street while implementing measures to slow traffic and improve pedestrian safety. A $16 million lane-narrowing project was eventually completed to reduce Washington Street between Edmund Street and Hamilton Boulevard.9

Highway Guides

East End I-74 – East Peoria, Illinois

Perspective from Interstate 474 east
Forthcoming Exit 15 provides return access to Peoria from Interstate 74 east. The ramp also provides part of a truck bypass of U.S. 24 through Creve Coeur and East Peoria.
This sign was replaced by 2015. Photo taken by Don Hargraves (09/02).
This diagrammatic sign was replaced with separate panels for the left-hand ramp (Exit 15) to I-74 west and the mainline continuation to Indianapolis. Bloomington is the ensuing control city for Interstate 74 east beyond the merge with I-474. Photo taken by Don Hargraves (09/02).
Interstate 474 defaults onto I-74 east with two lanes ahead of Interstate 155 south at the village of Morton. Exit 99 stems northeast to a loop ahead for I-74 west ahead of Pinecrest Drive. There is no direct access to Pinecrest Drive, which spans I-474 in this scene. Photo taken by Don Hargraves (09/02).
Perspective from Interstate 74 west
Construction during the I-74 and I-155 Improvement Project expanded Interstate 74 to six overall lanes from Morton Avenue (Exit 102) to the westbound split with I-474 (Exit 99). Work ran from April 2013 to fall 2016. Photo taken 05/24/18.

West End I-474 Illinois 6 – Peoria, Illinois

Perspective from Interstate 474 west
Leaving Bellevue, Interstate 474 becomes rural on the two mile drive to I-74 and Illinois 6 north.
This sign was carbon copied by 2011 with Clearview font. A replacement made of it by 2015 added exit numbers (Exits 0A/B) and switched the positions of Peoria and the Quad Cities. Photo taken by Don Hargraves (09/02).
A diagrammatic sign outlines the left-hand ramp (Exit 0A) for Interstate 74 west to Moline and Rock Island. Exit 0B follows for I-74 east back into Peoria. Photo taken by Don Hargraves (09/02).
A second diagrammatic sign, replaced by 2015, lies one half mile ahead of the directional cloverleaf interchange (Exits 0A/B) with Interstate 74. I-74 leaves Peoria for a rural trek west to Galesburg and north to I-80 and 280 at Colona. Photo taken by Don Hargraves (09/02).

Clearview sign replacements made along Illinois 6 south by 2011 carbon copied the local control city of Galesburg for I-74 west and retained Exits A-B. A subsequent change by 2015 assigned the ramps as Exits 0B/A while increasing the font size for I-74 and I-474. Photo taken by Joseph Barnes (08/13/16).
Illinois 6 winds southward from the Charter Oak Road underpass to reach Exit 0A for Interstate 74 west to Galesburg and Moline of the Quad Cities. Photo taken by Joseph Barnes (08/13/16).

Historic Perspective from Illinois 6 south

Through trucks were advised to take Interstate 474 around Peoria due to the substandard nature of I-74 through Downtown and across the Murray Baker Bridge. The recommendation was dropped following the completion of the Upgrade 74 project through Peoria in November 2006. Photo taken by Joseph Barnes (06/13/16).
I-74 traverses a series of forested hills through Kickapoo township to the Peoria city line at Exits 87A/B. I-474 wraps around the west side of the city southward to General Wayne A. Downing Peoria International Airport (PIA) and Bartonville while Illinois 6 extends north to Mossville. Photo taken by Joseph Barnes (06/13/16).
Arrow-per-lane (APL) signs were installed for the Interstates 74 and 474 split by 2015. I-474 sees Indianapolis for the continuation of I-74 east beyond Peoria. However signs posted for I-74 east at I-155 now reference Bloomington in place of the Indiana capital city. Photo taken 05/28/18.
High speed ramps connect Interstates 74 to 474 east and from I-474 to I-74 west. A cloverleaf interchange (Exit 87B) otherwise joins the freeway mainline with Illinois 6 as it extends the Peoria ring road north to IL 29 ahead of Chillicothe. Photo taken 05/28/18.
