State highway officials say work is scheduled to begin today on a bridge replacement project on US 150, west of Prospect in Orange County. Workers will be rehabilitating the bridge over Lost Creek, west of S.R. 56. One lane will be closed at a time. Stop lights will be installed on each end of the bridge to control traffic through the area. There will also be an 11-foot width restriction in place. It's estimated the project will be complete in July of 2014.
