Looking for slug line near Braddock Road

The two closest slug lines to Braddock Rd are on Old Keene Mill Rd in West Springfield & Burke. They are:
(1) at the Rolling Valley Mall commuter lot for many downtown and NoVa destinations and
(2) the Cardinal Forest line (for the Pentagon) that is located between the Shell Station and the Country Club Golf Course on Old Keene Mill Rd just east of the Rolling Rd intersection. Commuter parking is across the street at the Cardinal Plaza Shopping Center.

You can see more info on each of these slug lines (and downtown slug line locations to return in the afternoon) at the Morning Slug Lines tab on the Home page of this website.

A few years ago, there were proposala to start slug lines at the VRE stations in Burke (near the Target store) or at the West Springfield VRE station near Rolling Rd. But those slug lines never worked due to lack of participation.

No, but you could hitch a ride to L'Enfant Plaza. There's a bus that goes from there to the Navy Yard, our you could take the green line.
