Work will continue on phases two and three of the Navy Pier Flyover throughout June.
A major project milestone was completed on June 12, 2019 with the successful installation of the Flyover’s structural steel spine over the Ogden Slip. Installation of the steel spine is also complete for the southern portion of the path. Crews will now work to set the final pieces of spine adjacent to the Ogden Slip and the steel ribs, construct the bridge deck, which will be the surface of the path, and install path railings.
Check out the image below to see how crews installed the 105-foot long, 130,000-pound steel spine piece using a large crane set up in DuSable Park.
Phase three work in June will continue to accommodate the widened path through the existing limestone bridge houses on the east side of the Lower Lake Shore Drive bascule bridge. Crews are rehabilitating the movable bridge and working inside the bridge houses to remove old materials. They will also install temporary center locks between the two movable portions of the bridge and replace the structural steel and steel roadway grating in the westernmost bay of the bridge.
During stage one, the two westernmost, southbound lanes on Lower Lake Shore Drive over the Chicago River will be closed. Vehicles will still be able to access Lower Wacker Drive and southbound Lakeshore Drive while southbound Lower Lakeshore Drive is reduced to two lanes.
Daily lane closures on Lower Lake Shore Drive may also occur for ongoing roadway maintenance and other improvements. Please visit the Detours & Closures page to plan your trip accordingly.
