(Richmond, IN)--A couple of significant road and street closures are set to go into effect Monday.  One of them is State Road 227 between Richmond and Boston.  More specifically, the bridge over the railroad tracks near the south end of Niewoehner Road will be replaced in a project expected to take six months.  Also Monday, South 37^th Street will close between East Main and the stoplight between Kroger and Walmart.  The right lane of eastbound East Main will also be closed for a two-block stretch west of that intersection.  The closure is to allow for utility work at a new business and is expected to last through the end of the week.
