On June 29, crews began working around the Interstate 44 Meramec River bridges just west of Interstate 270. They are starting early work on the $51 million I-44 Meramec River Bridge replacement project.
For the most part, crews will be under the bridge, preparing for the construction of the new westbound bridge, and between the South Outer Road and eastbound I-44 to clear the area and prepare it for placing the project office and yard. After that, crews will be moving to the northwest corner of I-270 and I-44 to clear for drainage and work on a new ramp between I-270 and westbound I-44.
In June, KCI Construction was awarded the contract to replace both the eastbound and westbound I-44 bridges over the Meramec, just west of I-270.
Crews are starting with the new westbound bridge between the existing eastbound and westbound bridges, and then will shift eastbound traffic onto the new bridge to demolish and replace the existing eastbound bridge. When the new eastbound bridge is complete, eastbound traffic will shift to it, and westbound traffic will move to the new westbound bridge.
At this time, long-term lane closures are not expected, but there may be short-term lane closures on either eastbound or westbound I-44 during non-peak traffic hours.
Construction of the project is expected to continue into late 2021.
