The Indiana Department of Transportation is advising motorists that a new temporary traffic signal will be installed along U.S. 50 in Lawrence County. Beginning on or after today, Ragle Construction will start a bridge deck overlay project on U.S. 50 over Back Creek. One lane of the roadway will need to be closed to allow crews to perform work on the bridge. A signal will be installed at that location to move traffic through the work zone. Project completion is scheduled for September 30th.
