This year, the Missouri Department of Transportation has several projects planned along the I-44 corridor in St. Louis County and St. Louis City. This is part of planned rehabilitation projects for aging bridges along the I-44 corridor.  There are a number of bridges scheduled for work in 2018, and work along the I-44 corridor will continue through 2020.  Here's what you can expect this year:

I-44 bridge replacement – This project removes and replaces the driving surface from Murdoch to the River Des Peres and replaces the eastbound bridge over the BNSF Railroad. During construction the ramp from Shrewsbury to eastbound I-44 is closed. Drivers have shifted lanes – three eastbound and two westbound – during the project. The project is suspended for redesign, but is currently anticipated to be complete by the end of 2019.

I-44 – Bridge replacement.  This project replaces the eastbound and westbound I-44 bridges just west of I-270 over the Meramec. Replaces the bridges on the ramps between I-44 and eastbound and westbound Watson Road.   This year, the westbound Watson Road bridge to westbound I-44 will be closed for five months after Memorial Day. Work has begun on the project, which continues through 2021.
