Maryland Route 500 (MD 500) is a state highway in the U.S. state of Maryland. Known as Queens Chapel Road, the highway runs 2.22 miles (3.57 km) from Michigan Avenue at the District of Columbia boundary in Avondale north to MD 410 in Hyattsville. MD 500 connects Washington with the Prince George's County cities of Mount Rainier and Hyattsville. The state highway also connects those communities with a pair of stations on the Green Line of the Washington Metro. Queens Chapel Road was constructed as the original MD 210 from Washington to Hyattsville in the 1910s. MD 500 was built from Hyattsville through University Park to U.S. Route 1 (US 1) in the early 1930s. MD 500 assumed the course of MD 210 in the mid-1940s. The highway was relocated in West Hyattsville and expanded to a divided highway toward Washington in the early 1950s. MD 500 was truncated at MD 410 when University Park took over the highway prior to the construction of the Metro Green Line through the town in the late 1980s.
