MdQI is a consortium of public and private sector agencies and industry associations representing the Maryland transportation industry. The organization advocates for the highest quality in the planning, design, construction, and maintenance of Maryland’s transportation system.

The long-planned 355 interchange project managed by MCDOT improves capacity and access to the Medical Center Metrorail station and improves pedestrian and bicycle safety between the west and east sides of MD 355/Rockville Pike at the Institutes National Health (NIH) and Naval Support Activity Bethesda (NSA Bethesda), home to Walter Reed National Military Medical Center (WRNMMC).

“This was one of the most significant improvements to pedestrian safety in Montgomery County in recent years,” said County Executive Marc Elrich. “MD355/Rockville Pike at the Medical Center Metro Station has been a dangerous intersection for generations, and employees and visitors to these critical institutions deserve better. I am grateful for the recognition of MdQI.”

Construction of the complex project, which involved deep excavation carried out by drilling and blasting through rock, took around five years. The finished project includes:

  • A shallow pedestrian underpass under MD 355 that offers pedestrians and bicyclists a safe means of crossing the busy roadway.
  • A pair of new 120-foot-deep high-speed elevators and emergency stairs creating direct access between the station and the east side of MD 355.
  • A new elevator and stairwell between the existing Metrorail platform and the mezzanine.
  • Road surface improvements, such as a traffic light, pavement resurfacing, sidewalk/bike path, and median work.
  • Stormwater management facilities.

The largest employer is NIH, which is located on the opposite side of the street.

Thousands of people cross MD 355 every day to go back and forth between campuses and the Medical Center Metro located on the NIH side of MD 355.

“We are very grateful to receive this recognition for our work on this project,” said MCDOT Director Chris Conklin. “We know that the 355 Crossing project supports thousands of people and helps ensure their safety. Pre-COVID-19 projections tell us that the Medical Center Metro Station accommodates about 11,000 Metro riders daily, with an estimated 7,000 pedestrians crossing MD 355 to get to the Metro stop, Ride On, and on the way. shared use on the west side of MD-355.”
