Construction Update (3-22-19)

Northbound traffic between Archer Avenue and 5th Avenue is scheduled to be reduced to a single lane overnight Friday, March 22, for repair work to the Mile Long Bridge. The first lane will close at 7 p.m. All lanes will reopen by 5 a.m. on Saturday, March 23. Similar closures are scheduled overnight Saturday into Sunday, March 23.

During new bridge construction, customers will continue to use the existing Mile Long Bridge, and bridge repairs will continue in 2019 and beyond on an as-needed basis.

Please check the Daily Construction Alert for up-to-date closure information.

Customer Impacts

Whenever possible, the Tollway uses traffic shifts and shoulders to safely accommodate a work zone and keep as many lanes open during peak hours as were available before construction.

The Tollway is committed to maintaining four lanes of traffic in each direction throughout construction of the Mile Long Bridge.

A Regional Solution

The Central Tri-State Tollway is being reconstructed to increase capacity, reduce congestion and improve travel reliability. This work is part of the Tollway’s 15-year, $14 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. More than 220,000 vehicles use this portion of the Tri-State Tollway daily.

A detailed planning and refinement process is underway to complete a design concept for rebuilding the Central Tri-State Tollway (I-294). This process includes outreach efforts with customers, communities, businesses and partners to identify regional improvements and continue to refine the design details.
