The NPS owns and operates a 19-mile section to the south between MD 175 and theNew York Avenue/U.S. Route 50 split at the Prince George’s County/District of Columbia border. TheMaryland SHA owns and operates a 10-mile section of the B-W Parkway between I-695 and MD 175.The B-W Parkway was legislated byCongress in 1950 as an extension of thepark system of the District of Columbia,to be managed by the NPS. Additionally,this protected parkway was to link keyregional defense facilities including FortGeorge G. Meade.
