(KMOV.com) -- Upcoming road construction projects in Des Peres and St. Peters could mean traffic headaches for drivers.
A widening project on southbound 270 between Manchester and Interstate 44 begins on Monday night. Four lanes will remain open, but the roadway could become crowded.
A new diverging diamond interchange project will close the two loop ramps that connect northbound Mid Rivers Mall Dr. to westbound I-70, and southbound Mid Rivers to eastbound I-70.
