North Tri-State Tollway I-294 Reconstruction
Owner: Illinois Tollway
Location: Cook County, IL
The Tri-State Tollway is considered one of the most heavily traveled highways in the country. 2006 began the full reconstruction and addition of a fourth lane in each direction. In 2007, IEI began work on the Mid North Tri-State from Dempster to Willow Road. The project included reconstruction with widening of the northbound and southbound mainline I-294, bridge widening, and construction of a new bridge over Milwaukee Avenue.
In 2011, The American Council of Engineering Companies of Illinois present the team with a Merit Award in the category of special projects.
