Delaware Route 18

Delaware Route 18 (DE 18) is a state highway located in Sussex County, Delaware. It runs from Maryland Route 318 (MD 318) at the Maryland border east of Federalsburg, Maryland, east to U.S. Route 9 (US 9) in Georgetown. DE 18 runs concurrent with DE 404 from its intersection with that highway southeast of Bridgeville to the eastern terminus, where DE 404 continues eastward to Five Points on US 9. The route passes through rural areas of western Sussex County. What would become DE 18 was built as a state highway in stages during the 1920s and 1930s. By 1936, DE 18 was designated to run from the Maryland border east through Georgetown to Lewes. In 1974, the route east of Georgetown was replaced by US 9 and US 9 Business (US 9 Bus.). DE 404 was designated concurrent with the eastern portion of DE 18 by 1987.
