​Motorists Can Expect Single-Lane Closures, Flagging Operations 

(March 30, 2023) – The Maryland Department of Transportation State Highway Administration will begin a project next week to improve several state roads in Montgomery and Prince George’s counties. Crews will remove line stripping and pavement markings and apply a micro-surface coating that protects and extends the life of the asphalt. Weather permitting, work will be complete by early summer.

Work will take place weekdays 9 a.m. to 3 p.m., and overnights, 9 p.m. to 5 a.m. During work hours, motorists can expect lane shifts and single lane closures guided by a flagging operation. The State Highway Administration understands roadwork can be an inconvenience and asks motorists to be patient and stay alert in the work zones. The locations are as follows:
