Pictured is an aerial photo of the new, nearly completed Mercer County Engineer's facility on Mud Pike. Staff members will be moving from their current location at 321 Riley St. to the new site Friday through Monday. The agency's phone system will not be operational from 2 p.m. Friday to mid-morning Monday. Those needing to contact the office are asked to call central dispatch at 419-586-7724. An open house is planned at the new facility in late fall or early winter.
