ST. LOUIS COUNTY (KSDK) - Northbound Route 141 will be shut down this weekend at the Interstate 70 bridge.
The three-day closure will allow crews to repair damage done when a truck hit the bridge in June.
All traffic will be cleared off the road at 8 p.m. Friday, and several ramps will close in the area.
The Missouri Department of Transportation says drivers should use Route 364 or St. Charles Rock Road as an alternate route.
If everything goes as planned, the highway and ramps will reopen before the Monday morning commute.
