[ARCHIVED] UPDATES on the I-44 Meramec River Bridge Project

Recreation Center


MoDOT has provided the following update for January:

Construction on the new westbound Meramec River Bridge is continuing along well. Since the project began last year, crews have been working on the foundation and have gotten a good amount of it done.  Although you can see some of that work on the western side, as you drive by, we prefer that you watch on-going construction from the construction camera:  Please continue to pay attention and slow down as you drive through the work zone.

Over the next couple of months, crews will continue to work on those foundations, and we hope to have the girders placed for the new bridge sometime in February and the driving surface for the bridge sometime in March.  Of course, all that work is weather dependent.

Here’s what you can expect as we continue through the project this year.  We are expecting to move the traffic on eastbound I-44 onto the new westbound bridge sometime in late spring or early summer. That will let crews take down the eastbound bridge and start construction work there.

This summer, we will also close the ramp from westbound Route 366 (Watson Road) to westbound I-44 for five months, starting Memorial Day weekend.  We will be rebuilding the westbound Watson Road bridge over I-44 during that time.  You can anticipate a full closure of I-44 in both directions for a weekend to demolish the bridge, just after Memorial Day weekend. While the westbound Watson Road bridge is closed, drivers will be able to use Lindbergh to get to westbound I-44.


MoDOT has provided the following update for September:

Drivers heading west on I-44 during evening rush may want to consider adjusting their commute times, or using alternate routes, as MoDOT will close one westbound I-44 lane between I-270 and Bowles for Meramec River Bridge construction.

Starting at 7 p.m. Monday, October 1, the right lane on westbound I-44 will be closed just after the ramp to I-270. It will remain closed around the clock for the next three years as part of the on-going construction project.  

Access from Watson Road (Route 366), as well as northbound and southbound I-270, to westbound I-44 will shift, but will not change during this portion of the project. Drivers will also still be able to access the Soccer Park exit from westbound I-44. Drivers should expect greater congestion, especially during the evening rush period, in this area.

The three-year project replaces the westbound and eastbound I-44 bridges over the Meramec, makes improvements to the ramps between I-270 and I-44, and replaces the bridge from eastbound I-44 to eastbound Watson Road, and the bridge from westbound Watson Road to westbound I-44.  For more details on the project, please visit:


MoDOT has provided the following updates for August:

Over the next week, crews will be wrapping up the work to clear and remove material from the right-of-way within the construction zone - both underneath the bridge and around the I-44 and I-270 interchange to allow grading work for future improvements associated with the project.

Currently, crews continue to focus on foundation work for the new westbound bridge. As part of the work, the pedestrian trail along Yarnell Road has been closed for safety reasons. It is anticipated that the trail will remain closed through 2020.

Although the project will require lane closures at some point, there are no anticipated dates for lane closures along I-44 at this time. Information about future lane closures will be shared when it is available. 



With work beginning on the new river bridge at I-44, the shared use path from south of the existing eastbound bridge to north of the existing westbound bridge will be closed immediately due to safety concerns. Check back for progress updates.
