North Avenue at I-294 Interchange Project
The North Avenue at I-294 Interchange Project delivered a new exit ramp from the southbound Tri-State Tollway (I-294) to County Line Road to improve access to North Avenue and Lake Street, as well as reduce congestion and improve traffic flow on existing roadways within the project area. The new ramp is now open. Read more here.
In partnership with the Illinois Tollway and the cities of Northlake and Elmhurst, Cook County led the project's design and is constructing the local road improvements.
The project was completed in 2025.
