St. Louis Work Zones for September 17 - 23

ST. LOUIS – Maintenance crews continue to work daily on patching potholes and touching up striping on state roads around the region. Drivers should be aware of slow moving maintenance operations on roadways.

When drivers see a MoDOT vehicle with flashing lights, they should remember to slow down or move over to avoid the work ahead. Often three or more maintenance vehicles will be spaced out over some distance to complete maintenance work. Drivers are encouraged to pay attention while driving through work zones.

For more on roadway closures due to construction, additional work zone information and real-time roadway weather conditions go to http://traveler.modot.org/map.  For real-time traffic, visit www.gatewayguide.com. All work is subject to change and may be shifted due to inclement weather.
