Interstate 57/294 Interchange Project

The Illinois Department of Transportation in partnership with the Illinois Tollway is planning to construct a $600 million improvement involving Interstate 57, Interstate 294 and Illinois Route 83 (147th Street). The improvement will consist of constructing a full interchange with ramps between Interstate 57 and Interstate 294, improvements to 147th Street including a median to accommodate left turn lanes between Kedzie Avenue and Western Avenue/Dixie Highway, and construction of a partial interchange with ramps between Interstate 294 at 147th Street. Interstate 57 at Interstate 294 is one of two locations in the country where two Interstates meet without connecting. The completed Interstate 57/294 Interchange Project will connect these important Interstate highways as well as reduce travel times and congestion on local routes that are being used to facilitate the Interstate to Interstate linkage. It is anticipated the construction project will consist of up to 11 contracts to be implemented over a number of years.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.

UPDATE- October, 2014
IDOT expects all lanes of IL Route 83 west of I-57 to be reopened by late November 2014. Work to reconstruct pavement west of I-57 and on Dixie Hwy./Western Ave. should be complete in late Spring 2015.


Contract #2 calls for the staged replacement of the structure at Kedzie Avenue over I-57 with a new, longer structure which will carry Kedzie Avenue over I-57 and future Ramps B and M. The Kedzie approaches will also be reconstructed adjacent to the bridge. Resurfacing will be done from the limits of reconstruction up to the Kedzie Avenue signalized intersections on each side of the bridge. The curb and gutter, concrete median, guardrail and detector loops were replaced throughout the project limits.
