(Richmond, IN)--One of the two routes drivers generally use to detour around the Depot Overpass replacement project in Richmond will be closed Monday.  The railroad crossing at North 8^th Street will shut down at noon Monday to allow crews to relocate water lines as part of the project.  North E between 8^th and 10^th Street will also shut down.  The city recommends using 12^th Street as a detour.  The area is expected to reopen at midnight Monday night.
