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 and pavement rehabilitation – This project removes and replaces the driving surface from Murdoch to the River Des Peres and replaces the eastbound bridge over the Burlington Northern Santa Fe Railroad. During construction the ramp from Shrewsbury to eastbound I-44 will be closed in early spring 2018.  Drivers will have shifted lanes – three eastbound and two westbound – during the project. The project has begun. The bridge project will be completed in late 2018, while final resurfacing will be complete in late spring 2019.

I-44 – Pavement repairs. Resurfacing from east of Murdoch Avenue to Route 141. Work will be complete by the end of 2018.

I-44 – Signal replacements. This project replaces the signals at the Berry Road interchange. Work will be complete by the end of 2018.

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.  Work starts on the westbound I-44 bridge in late 2018. The project continues through 2021.
