Major Work Will Improve Safety and Help Ease Congestion on MD 355 in Northern Montgomery County

(February 25, 2019) – This month, the Maryland Department of Transportation State Highway Administration (MDOT SHA) will begin an intersection improvement project at the MD 355 (Frederick Road)/West Old Baltimore Road intersection. This project is approximately one-half mile in length on MD 355 between south of Greenridge Drive and Brink Road. The $9 million project should be complete by year end 2020.

The main part of the project is to realign the MD 355/West Old Baltimore Road intersection to 90 degrees, which will improve sight distance for drivers and bicyclists. Other work includes:
  • Widening MD 355 to provide a northbound MD 355 left turn lane, acceleration and deceleration lanes on southbound MD 355 and a left turn lane on West Old Baltimore Road with MD 355;
  • Reconstructing the MD 355 traffic signal to include the added turn lane;
  • Milling and resurfacing existing roadways and installation of new pavement markings;
  • Constructing a shared-use  path, relocate 24-inch water main; and
  • Replacing a drainage culvert.
Motorists can expect single lane closures on MD 355 and West Old Baltimore Road Mondays through Fridays between 9 a.m. and 3 p.m. and Sunday nights through Friday mornings between 7 p.m. and 6 a.m. Approximately 18,000 vehicles use this section of MD 355 daily, so motorists should leave extra commute time during construction.

MDOT SHA’s contractor for the work is Rustler Construction of Upper Marlboro. While MDOT SHA and its transportation partners work hard to maintain safe traffic mobility in work zones, each driver needs to actively modify his or her driving style to help prevent crashes. Stay alert and look for reduced speed limits, narrow driving lanes and highway workers. Slow down and don’t follow too closely. Work Zone Safety is in Your Hands.
