Missouri Department of Transportation crews will close Route 141, the Earth City Expressway, at the railroad crossing just south of Route 370 Friday morning so crews can replace the railroad crossing.
That portion of the road is closing at 8 a.m. Friday, and will reopen before noon Tuesday, Oct. 9, MoDOT stated in a news release.
All work is weather-permitting.
Since Route 141 is will be closed, MoDOT is alerting drivers to use alternate routes.
A MoDOT spokesperson stated that detours will not be posted, however, drivers can remain on Route 370 to I-270, take I-270 south and head west on St. Charles Rock Road to detour around the construction.
