The Purple Line is a 16-mile light rail line that will extend from Bethesda in Montgomery County to New Carrollton in Prince George’s County. It will connect to four branches of the Metro rail system at Bethesda, Silver Spring, College Park and New Carrollton, as well as all three MARC commuter rail lines, and Amtrak. Twenty-one stations are being constructed along the alignment. Once complete, the light rail will operate mainly in dedicated or exclusive lanes, allowing for fast, reliable transit operations.
The Public-Private Partnership (P3) project also includes the completion of the Capital Crescent Trail between Bethesda and Silver Spring, the completion of the Green Trail along Wayne Avenue to Sligo Creek Parkway, and the construction of a bike path through the University of Maryland Campus. Close coordination is occurring with the Washington Metropolitan Area Transit Authority, Montgomery and Prince George’s counties, the Maryland-National Capital Park and Planning Commission, State Highway Administration, and local municipalities in the project area.
Installation of erosion and sediment control measures, clearing and grubbing, grading, and building demolition is in progress along the 16-mile alignment. At the Bethesda Station South Entrance, which is encompasses a shaft and cavern in rock, drilling of soldier piles for the support of excavation in the overburden has also begun. The extensive utility work includes water, sewer, and power lines. Underground portions of the project will be excavated by cut-and-cover and the New Austrian tunneling method (NATM).
The new Purple Line will extend from Bethesda in Montgomery County to New Carrollton in Prince George’s County, Maryland. It will provide a direct connection to the MTA’s current Metrorail system, as well as to Maryland Area Rail Commuter (MARC), Amtrak, and local bus services. The Purple Line will link Bethesda, Silver Spring, Takoma/Langley Park, the University of Maryland at College Park, and New Carrollton. Twenty-one stations are planned along the route.
The Purple Line is currently scheduled to open for service in 2022. For more information about the project, visit MTA’s website by clicking here.
