You can add two more road projects to area motorist challenges.  Those drivers in Preble County will be dealing with the continuation of the State Route 503 work focusing on a pair of culvert replacements.  State Route 503 will be closed between Prymont and Eaton-Lewisburg roads through June 23rd.  Drivers will be detoured onto US 35, 127 and I-70.  And U.S. 35 will have pavement and resurfacing done beginning today between the town limit of Eaton and Preble County Line Road.  Lane restrictions will be in effect daily from 7 a.m. to 7 p.m.
