The main north–south highway through Dover is U.S. Route 13, which runs through the main commercial strip of Dover on the multi-lane, divided Dupont Highway. An alternate route of U.S. Route 13, U.S. Route 13 Alternate, passes through downtown Dover on Governors Avenue. The Delaware Route 1 turnpike, which provides the main route to Wilmington and the Delaware beaches, passes to the east of Dover. It ends near the Dover Air Force Base and DE 1 continues south on Bay Road. U.S. Route 113 formerly ran along Bay Road from Milford to US 13 near the State Capitol Complex, however it was decommissioned in 2004 to avoid the concurrency with DE 1 between the Dover Air Force Base and Milford. Delaware Route 8 is the main east–west route through Dover, passing through downtown on Division Street and West Dover on Forrest Avenue. It continues west toward Maryland to provide access to the Chesapeake Bay Bridge. Dover is one of only four state capitals not served by an interstate highway.
