DETOURS AND CLOSURES
Phase three of the Navy Pier Flyover construction project kicked off the end of April 2019 with the rehabilitation of the movable bridge across the Chicago River. This work will be completed in multiple stages with varied traffic impacts.
This stage of the project will close the two easternmost, northbound lanes on Lower Lake Shore Drive over the Chicago River. During this closure, access to Illinois Street and Grand Avenue from the northbound lanes of Lower Lake Shore Drive will be restricted, and a detour will be set up to Columbus Avenue.
Northbound traffic crossing the river will only be able to access the entrance ramp to northbound Upper Lake Shore Drive. All other turns to and from Lower Lake Shore Drive will be maintained. See maps below.
Pedestrian and Bicyclist Impacts:
Access to the Lakefront Trail will remain open during construction, the permanent trail was reopened on February 2, 2021. Work is ongoing through the bridge house tunnels and along the trail.
Nearby residents may experience some construction noise during this period from jackhammers and saws. This work is being scheduled during daytime hours to limit the noise impact.
The maps below illustrate lane closures for the third stage of phase three construction. The temporary trail was taken out of service and crews are finishing up necessary roadway work ahead of a vehicle traffic stage change in mid-March that will return access to Illinois and Grand from northbound Lower Lake Shore Drive.
