Carrying up to 150,000 vehicles a day, the Mile Long Bridge is a vital piece of infrastructure to Chicago, its southwest suburbs, and the Central Tri-State Tollway (I-294).
The $500 million Mile Long Bridge Project began in the summer of 2019 and was completed in 2023. Work included the construction of two new, wider bridge structures, as well as stormwater, drainage and related infrastructure improvements. Construction on the new northbound bridge was completed in 2020 and work on the new southbound bridge was completed in 2022.
TranSystems (formerly OMEGA) served as both Owners Representative and Construction Corridor Manager for both the northbound and southbound projects.
