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.   Here's what you can expect this year:

I-44 – Safety improvements. Installs selected safety improvements to reduce the likelihood of wrong way drivers at various interstate ramps on I-44 between the city limits and the Franklin County line.

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 Watson Road.  Work has begun on the project, which continues through early 2022. 

I-44 – Bridge rehabilitations. Makes repairs to the bridges at Osage Street, Viaduct, and Route OO, Six Flags, BNSF and UP railroad and Route 109 and 1st Street. Also includes work on the I-44 Loop Road bridge at Fox Creek. Work begins in late spring 2020.
