ST. LOUIS (KSDK) – Expect delays if you're driving downtown Sunday night.

The Missouri Department of Transportation will close all lanes of eastbound Interstate 70 between Pine Street and the Poplar Street Bridge starting at 6 p.m. One eastbound lane will reopen at 5 a.m. Monday, and the rest of the highway should be open before 3 p.m.

Crews are removing the retaining wall along the interstate near Walnut Street and making pavement repairs as part of the Park Over the Highway project.

In the meantime, drivers will take the Pine Street ramp to southbound Memorial Drive and follow southbound Memorial to I-55 or the Poplar Street Bridge.
