ST. CHARLES COUNTY, Mo. — The Missouri Department of Transportation will close Route 370 flyover exit ramp to eastbound Interstate 70 for bridge work starting Wednesday, April 13, at 6 a.m.

To access eastbound I-70, drivers will detour to westbound I-70 and exit at Mid Rivers Mall Drive, then turn east on Veterans Memorial Parkway and merge onto eastbound I-70, according to a press release. 

The project is expected to last about a month.
