(September 23, 2025) – The Maryland Department of Transportation State Highway Administration is starting construction on a project to replace the bridge on MD 77 (Rocky Ridge Road) over Beaver Branch and under the Maryland Midland Railway in Rocky Ridge, Frederick County. The $7.1 million project will construct a new, wider bridge and provide drainage improvements. 

The existing bridge was built in 1928. While safe for use, the bridge is nearing the end of its service life and needs replacement. Given the confined work area, the State Highway Administration will close this portion of MD 77 starting on Monday, September 29. Traffic will be detoured during construction of the new bridge, which is expected to take eight months. 

The detour route will direct eastbound and westbound motorists to use MD 76 (Motter’s Station Road), Appolds Road and Old Frederick Road. Trucks will be directed to MD 77, MD 550 (Woodsboro Creager town Road) and MD 194 (Woodsboro Pike).

The project is starting construction this month and is anticipated to be finished in summer 2026. Learn more about this project by clicking here. Brawner Builders Inc., based in Hunt Valley, will be the primary contractor on this project. 

The State Highway Administration works hard to maintain safe traffic mobility in work zones for our crews as well as customers. Motorists are asked to stay alert, stay focused and be aware of reduced speed limits and changing driving patterns. Slow down and move over in work zones. It’s the law. Motorists in need may dial #77 on their mobile devices for assistance.​
