And after u take the subway what bus do u take afterwards? You can take Metro to Silver Spring (red line), which has a large bus terminal. From there, Take Z29 BUS towards SOUTH LAUREL PARK AND RIDE. Its about 40 minutes to Beltsville, and the VAN DUSEN RD & LAUREL PARK DR bus stop is for the hospital. it looks like you can take the red line to Rhode Island ave stop. From there the bus probably depends on where specifically in Beltsville you are going. Use the link below putting in your starting and ending location, and it will give you options |
