Maryland Route 414 (MD 414) is a state highway in the U.S. state of Maryland. The highway runs 5.64 miles (9.08 km) from the beginning of state maintenance near Oxon Hill east to MD 5 in Silver Hill. MD 414 connects the inner suburbs of Oxon Hill, Marlow Heights, and Silver Hill and provides access to National Harbor. The highway was constructed through Oxon Hill and Marlow Heights in the early 1930s. MD 414 was extended through Silver Hill along the old alignment of MD 5 when that highway bypassed Silver Hill in the early 1950s. The highway was expanded to a divided highway between Marlow Heights and Silver Hill in the early 1970s, around its interchange with Interstate 95 and I-495 in the early 1980s, and around MD 210 in Oxon Hill in the late 1980s. MD 414 was reconstructed around MD 210 again in the mid-2000s with the construction of National Harbor and the new Woodrow Wilson Bridge.
