Sabra & Associates, Inc. (SAI) was responsible for developing the complex Utility Relocations associated with a proposed Pedestrian and Bicycle Underpass, the addition of Deep Elevators, a Transportation System Management (TSM) / Transportation Demand Management (TDM), and an altenate Grade Separation of MD 355 under South Wood Road (NMMC)/South Drive (NIH).  The impacted Utilities included PEPCO (Electrical Conduit Ductbank and Manholes, and Overhead Power Lines for 110kV Transmission, Primary and Secondary Distribution, and Streetlighting, with co-mounted Comcast Cables), Verizon of Maryland (Telephone Conduit Ductbank and Manholes, Overhead Telephone Lines, and direct buried (formerly MCI) Fiber-Optic Cables), Washington Gas Mains, Washington Suburban Sanitary Commission Water Mains and Sanitary Sewers, and WMATA Private Sanitary Sewers. The development of conflict resolutions and new services required coordination with all stakeholders as well as the utility companies. SAI is responsible for the performance specification and other documents needed for the project to be advertised for a winning Design/Build Team. SAI will provide construction support services.


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 the 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 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.
