Navy Pier Flyover

Enhancing Chicago's Lakefront Trail


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.

Starting March 30, one lane of southbound upper Lake Shore Drive will be closed over the Chicago River to complete repairs on the west bridge houses adjacent to the Lake Shore Drive bridge. The closure is anticipated to last four weeks. A similar closure was completed last fall for northbound upper Lake Shore Drive to repair the east bridge houses.

Next Monday, April 6, starting at 9:30 a.m. upper and lower Lake Shore Drive will be fully closed to complete a trial bridge lift ahead of the boat run season. A detour will be in place during the closure which should be finished by 2:30 p.m.

Southbound traffic will be directed onto westbound Grand Avenue to southbound Columbus Avenue, to eastbound Lower Wacker Drive and back to Lake Shore Drive. Northbound traffic will be directed onto the Randolph ramp to westbound Lower Wacker Drive, to northbound Columbus Avenue, to eastbound Illinois Street and back to Lake Shore Drive. The closure will end as soon as the trial lift is completed, and the bridge is secured. Tuesday, April 7, is the backup date if weather prevents the work from happening on Monday.

Additional Closures:

Starting March 16, 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 turning movements 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, 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 beginning March 16 for the third stage of phase three construction.
