Maryland Route 313

Maryland Route 313 is a state highway located on the Eastern Shore of Maryland in the United States. The 75.72-mile (121.86 km) route runs from U.S. Route 50 in Mardela Springs, Wicomico County north to Maryland Route 213 and Maryland Route 290 in Galena, Kent County. It is predominantly a rural two-lane road that runs through agricultural areas a short distance west of the Delaware border, with the exception of a four-lane divided bypass of Denton shared with Maryland Route 404. MD 313 serves many communities, including Sharptown, Eldorado, Federalsburg, Denton, Greensboro, Goldsboro, Barclay, Sudlersville, Millington, and Massey. The route intersects many major roads, including Maryland Route 54 in Mardela Springs, Maryland Route 404 in the Denton area, Maryland Route 302 in Barclay, Maryland Route 300 in Sudlersville, and U.S. Route 301 near Massey.

The designation MD 313 was first used prior to 1927 for the road running from Eldorado to Galena, while the portion south to Mardela Springs was designated a part of U.S. Route 213. By 1940, the route was extended to Mardela Springs following a realignment of US 213. A few realignments to MD 313 had occurred by 1960 including one that moved the route to a new road between Federalsburg and Denton. In the 1980s, a four-lane divided bypass of Denton was built and the former alignment of MD 313 in the town became Maryland Route 619. This divided highway was extended further south of Denton in the early 2000s. The remaining two-lane portions of MD 313 that are concurrent with MD 404 are slated to be upgraded to a four-lane divided highway to provide relief to beach traffic along MD 404, a part of the main route between the Chesapeake Bay Bridge and the Delaware beaches.
