St. Louis – Road crews spent the night stacking concrete barriers and sandbags along Interstate 44 in Valley Park.
During the Friday morning rush hour, only one westbound lane was open as work continued.
MODOT's Jack Wang said crews will do the same thing along the eastbound lanes.
Wang said it's hard to tell when or if the water will reach the freeway.
But Highway 141 is closed at the I-44 interchange in Valley Park because of flooding from the Meramec river.
