Maryland Route 150

Between 1942 and 1944, MD 150 was reconstructed as a four-lane divided highway with interchanges to improve access between Baltimore and the Glenn L. Martin Company aircraft manufacturing plant in Middle River.[1][2] MD 150 is a part of the National Highway System as a rail-to-truck intermodal freight transport connection from its western terminus at US 40 to I-95 within Baltimore.MD 150 turns south onto Ponca Street, a four-lane divided highway that has a ramp to southbound I-895 toward the Baltimore Harbor Tunnel.MD 150 passes under a Norfolk Southern Railway spur from Amtrak's Northeast Corridor to the former Charles P. Crane Generating Station and intersects Marshy Point Road, which leads into Dundee Natural Environment Area.Graces Quarter Road serves as a connector to the main section of the county highway, which heads east into a unit of Gunpowder Falls State Park.[6][7] MD 150 was constructed as a macadam road from the Baltimore city line to the crossing of Middle River in 1924; this section would be widened with concrete shoulders to a width of 18 to 20 feet (5.5 to 6.1 m) by 1926.[10] Suburban development in Dundalk and Essex and the establishment of the Glenn L. Martin Company aircraft manufacturing plant in Middle River in 1929 resulted in heavy traffic along MD 150.[7] Relief did not come until just before World War II when MD 150 from Baltimore to Middle River was deemed a vital defense connection between the city and the Martin aircraft plant.[12] MD 150 was expanded to a four-lane divided highway from Dundalk Avenue in Baltimore to east of the Martin aircraft plant in Middle River between 1942 and 1944.
