U.S. Route 13 (US 13) is a north–south U.S. highway established in 1926 that runs for 517 miles (832 km) from Interstate 95 just north of Fayetteville, North Carolina to the northeastern suburbs of Philadelphia, Pennsylvania, in Morrisville. In all, it traverses five states in the Atlantic coastal plain region, following the Atlantic coast more closely than does the main north–south U.S. highway of the region, U.S. Route 1. Its routing is largely rural, the notable exceptions being the Hampton Roads area and the northern end of the highway in Delaware and Pennsylvania. It is also notable for being the main thoroughfare for the Delmarva Peninsula and carrying the Chesapeake Bay Bridge-Tunnel to it in Virginia.
