US 17-1 was an original US Route appearing in 1927. It began at US 17/NC 20 Market St in Wilmington, then headed north on 4th St to Nixon St east to today's McRae St. to leave the Wilmington area (none of these streets US 17-1 used in Wilmington is primary highway now). US 17-1 proceeded north on Castle Hayne Rd. At Castle Hayne US 17-1 used Old Bridge Site Rd to cross the NE Cape Fear River.
