While the Delaware Department of Transportation is responsible for maintenance of 89 percent of roads in the state, DelDOT does not plow roads and streets that are maintained by towns or cities. DelDOT also does not plow roads within privately owned subdivisions. DelDOT does plow some roads that are within city or town limits, but only those that are designated state maintained roads. Residents of incorporated towns or cities should first check with local government officials to learn if your street or road is municipally maintained.
For example, in the town of Greenwood, DelDOT plows Market Street, because that road is part of Del. 16, which is a major route for motorists heading east and west in Sussex County. In Dover, DelDOT plows North and South Dupont Highways for the same reason.
