Baltimore-Washington-Marshall Airport Transportation

BWI is one of the few U.S. airports to have a light rail terminal and a train station at the airport. Maryland Transit Administration's Light Rail links Baltimore County and Anne Arundel County to BWI. You can catch the light rail at many stops and take it all the way to the airport. Trains run every 30 minutes during peak travel hours. In addition, Amtrak’s Northeast Corridor train brings travelers from as far north as Boston and as far south as D.C. to the BWI Marshall Rail Station. A free shuttle connects the station to the airport. Many travelers pick up the MARC Penn Line from Penn Station, Baltimore, to BWI. You can also pick up a direct train line from D.C.’s Union Station to BWI. The Penn Line is not available on weekends.

From the Washington, D.C., metro system, riders can take the green line to Greenbelt station in Maryland. There they can catch WMATA's Metrobus Route B30. This takes riders to the MARC Camden Line and allows travelers to continue toward BWI via light rail transit. MTA’s Bus Route 17 offers 24-hour, 7-day service to the airport. In addition, travelers can catch a BWI bus from the Patapsco Light Rail Station. Gaithersburg and other nearby cities are served by bus routes that connect to BWI. From Annapolis, you can take Annapolis Transit Route C-60 to BWI. Columbia is served by Howard transit which links the area to BWI. Coastal Maryland is served by a private BayRunner Shuttle.

Drivers usually approach the airport via I-95 north-south to I-195 spur which ends at the airport. If driving, you can expect long delays due to urban traffic problems. Parking choices include hourly garages, long term garages, and long term parking lots. The car rental lot is located on New Ridge Road on the airport grounds. Visitors can drop off their rental car and take a free shuttle to the terminal.
