Navy Pier Flyover

Enhancing Chicago's Lakefront Trail

DETOURS AND CLOSURES

Vehicle Impacts:

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. On northbound Upper Lake Shore Drive, one right lane will reopen on Monday October 12. See maps below.

Additional daytime lane closures on northbound and southbound Upper Lake Shore Drive will be required to install new traffic gates adjacent to the moveable bridge. Other daily lane closures may be utilized as needed for individual operations.

    • On October 14, the two left lanes on northbound and southbound Upper Lake Shore Drive will be closed from 9:30 a.m. until 3:30 p.m. to install new bridge gates along the middle of Lake Shore Drive.
    • On October 15, the two right lanes on northbound and southbound Upper Lake Shore Drive will be closed from 9:30 a.m. until 3:30 p.m. to install new bridge gates along the outside of Lake Shore Drive.
    • October 16 is scheduled as a backup day if needed due to weather or other issues.

The exit ramp to Illinois Street will remain open throughout these operations.

Pedestrian and Bicyclist Impacts:

Access to the Lakefront Trail will remain open during construction, however bicyclists and pedestrians will be moved into a new, temporary two-way path created in a protected northbound traffic lane during this work.

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.
