Maryland Route 520 (MD 520) is a state highway in the U.S. state of Maryland. Known as Whites Neck Road, the state highway runs from a dead end at a boat ramp north to MD 239 near Bushwood in western St. Mary's County. MD 520 was constructed in 1933. Route description MD 520 begins at a boat ramp at the southern end of Whites Neck adjacent to the mouth of Whites Neck Creek at St. Catherine Sound, an embayment of the Wicomico River. The wide two-lane undivided state highway heads west then north through farmland. MD 520 veers northeast through a forested area before crossing Whites Neck Creek and reaching its northern terminus at MD 239 (Bushwood Wharf Road) near the community of Bushwood. History MD 520 was constructed as a gravel road in 1933. The state highway was widened and resurfaced with bituminous concrete in 1956. MD 520 has changed very little since then.
