St. Louis Work Zones for August 4 - 10

ST. LOUIS – Drivers who use the ramp from Lewis Road to access westbound Interstate 44 will need to determine alternate routes, starting next week, as crews close a ramp through late 2023.

Starting at 6 p.m. August 8, crews will close the ramp from Lewis Road to westbound I-44. 

The ramp is projected to reopen over the winter.  It will close again next year when the construction on the bridges continues.

For the remainder of this year, drivers can also expect various off-peak lane closures on the westbound bridge over the Meramec near Eureka.

The marked detour for the closure will be to take I-44 eastbound to Antire Road (Exit 269), cross over the interstate and access westbound I-44. 

For more on roadway closures due to flooding, 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.
