Grand Bridge Replacement over Highway 44 – 2016
What is the situation?
The Grand bridge over I-44 in St. Louis City is old. Built in 1969, the bridge is one of a few remaining bridges along I-44 that are below the standard height for bridges over an interstate. The bridge is deteriorated and needs to be replaced.
What is the current plan?
This summer, MoDOT will remove, raise and replace the Grand bridge over I-44 in three stages. During the work, at least one lane will remain open in each direction on Grand. Construction will start in June, with all driving lanes reopen by the end of the year. Some work that doesn’t impact the driving lanes will be completed in spring 2017.
During construction, at least one lane will remain open in each direction. Grand will not be completely closed. Drivers will not be able to make a left turn at the bridge – that means southbound drivers will not be able to access eastbound I-44 and northbound drivers will not be able to turn onto the westbound I-44 ramp. There will be short periods when drivers will not be able to make right turns from Grand onto the interstate.
When the bridge construction is complete, drivers will have two northbound and two southbound lanes, and a dedicated left turn lane. In addition, cyclists will have a dedicated lane along the bridge in both directions. Pedestrians will have a sidewalk on each side, as well.
The department will continue to take comments on the potential impacts of the project until Monday, March 21.
