MD 75 signMototists Can Expect Daytime Single-Lane Closures Beginning Monday (August 24, 2023) - The Maryland Department of Transportation State Highway Administration will begin a project to improve nearly five miles of pavement on MD 75 (Green Valley Road) in New Windsor beginning Monday, August 28. Crews will work between the Frederick/Carroll County line and MD 31 (New Windsor Road). The project should be complete by mid-October, weather permitting. The patching project will require single-lane closures guided by a flagging operation Mondays through Fridays 8 a.m.-4 p.m. The State Highway Administration’s contractor, Francis O. Day Co, of Rockville, will use signs, barrels, cones, flaggers, and arrow boards to safely guide motorists through the work zone. Motorcyclists should use extra caution for uneven pavement during the resurfacing project. The State Highway Administration understands lane closures associated with road construction may be an inconvenience, but the work is necessary to maintain a world-class transportation system. Drivers should slow down and pay close attention while driving through work zones. Motorists in need may dial #77 on their mobile devices for roadside assistance.
