Coordinating agencies:

  • Maryland Department of Transportation, State Highway Administration
  • United States Navy
  • Department of Defense, Defense Access Road Program
  • Federal Highway Administration
  • Washington Metropolitan Area Transit Authority
  • National Institutes of Health
  • Maryland-National Capital Park and Planning Commission
  • National Capital Planning Commission
  • Maryland Historic Trust


  • Montgomery County Department of Transportation funded an Environmental Assessment
  • The project is fully funded at $68.174 million for design and construction from two funding sources:  $28.174 million in Defense Access Road Program funds from the Department of Defense, and by a $40 million grant from the DoD Office of Economic Adjustment (OEA) for transportation projects at BRAC-impacted military medical facilities.
  • OEA provided a $34 million supplemenmtary award in 2016, bringing total funding for theis project to over $102 million.  Additionally, the Crossing Project has been combined with the SHA Intersection Improvement Ppoject at MD 355/Jones Bridge Road.


  • Construct a pedestrian underpass between the Medical Center Metro station and the campus of Naval Support Activity-Bethesda, which includes the Walter Reed National Military Medical Center
  • Construct deep elevators to the Metro platform near the Navy gate at South Wood Drive
  • Develop at-grade Transportation Systems Management and Transportation Demand Management elements to promote pedestrian safety and improve traffic operations.



The MD 355 Crossing (BRAC) project is located in Bethesda, Maryland, a densely populated and developed area inside the Capital Beltway (I-495), and adjacent to the National Institutes of Health (NIH) and Naval Support Activity-Bethesda (NSAB), which is home to the Walter Reed National Military Medical Center (WRNMMC). The focus of project is on the intersection of MD 355/Rockville Pike and South Wood Road/South Drive.

The purpose of the project is to improve the movement of the traveling public between the west and east sides of MD 355/Rockville Pike at its intersection with South Wood Road and South Drive in Bethesda. The project is intended to:

  1. enhance/improve access to mass transit facilities; 
  2. improve the mobility and safety of pedestrians and bicyclists crossing MD 355/Rockville Pike,
  3. improve traffic operations at the signalized intersection of South Wood Road, South Drive, and MD 355;  and
  4. improve the capacity and operation of the intersection of MD 355 (Rockville Pike) and Jones Bridge Road/Center Drive.

The project includes a proposed shallow underpass below MD 355, new deep high-speed elevators and emergency stairs on the NAVY side, and a new deep tunnel connection between the new deep high speed elevator and the existing Metrorail tunnel. In addition, roadway surface improvements include traffic signal, pavement resurfacing, full-depth pavement, sidewalk/bike path, median work, and stormwater management facilities; extension of the southbound MD 355 left turn lane in the existing median of MD 355 to improve queuing for vehicles turning left onto South Wood Road; and MD 355/Jones Bridge Road intersection improvements (curb radius expansions and reductions, improved sidewalks and a shared use path, pedestrians crosswalks, traffic signals, drainage, and paving).  Additional information about the MD 355 (Rockville Pike)/Jones Bridge Road intersection project can be fiound here.
