Welcome to the Interstate 57/294 Interchange Project Website!


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.

Did you know work zone fatalities are down 29.6 percent compared to 2003? Aggressive law enforcement and awareness campaigns and significant improvements to work zone safety traffic control reduced Illinois work zone fatalities from 44 in 2003, including 5 workers, to 31 with 2 workers killed in 2008. So, Give ‘em a brake…slow down for their sake and yours!
