January 25, 2017 – The Interstate 74 Bridge Corridor project involves the replacement of the I-74 Bridge and nearly eight miles of corridor improvements. It has been the number one transportation priority in the Bi-State Region since 1998. It is in need of reconstruction due to crashes, recurring congestion, and significant maintenance. The bridge itself is functionally obsolete with no shoulders. The Iowa-bound span was built in 1935 and the Illinois-bound span in 1959.
The Central Section of the I-74 Bridge Corridor project from south of Avenue of the Cities to Middle Road has been value engineered to reduce costs and the construction period from 8 to 3.5 years. Design plans are complete for the entire central section, which includes the entire Illinois portion of the project. The Iowa portion of the project north of Middle Road to 53rd Street is 3.5 miles in length and is an independent project. The design for the North Section started in 2016 and should be completed by 2018.
