"The B&A Trail serves as Anne Arundel’s linear island in the most congested part of the county. This park provides a haven for bikers, strollers, and hikers. The B&A Trail, a rails-to-trails park that is part of the East Coast Greenway, follows the old Baltimore and Annapolis Railroad from Glen Burnie in the north (not quite Baltimore) to Annapolis in the south. The 115-acre park runs as a 10-foot-wide paved path that follows a more or less straight line along Ritchie Highway and the more twisty Baltimore- Annapolis Boulevard to MD 50 heading into Annapolis.
It’s interesting to note that the boulevard and the highway, built to accommodate the increased automobile traffic, hastened the end of the short line railroad. Nowadays, Baltimore- Annapolis Boulevard has been increasingly displaced by Interstate 97, the Baltimore–Annapolis Expressway, built to connect Maryland’s capital with its largest city. So the railroad corridor, once rendered obsolete, has now become popular again, despite the presence of the boulevard, the highway, and the interstate."
