The Puncheon Run Connector is an unnumbered four-lane freeway in the city of Dover in Kent County, Delaware. It is named after Puncheon Run, a stream it follows. It provides a connection from U.S. Route 13 (US 13) east to the northbound direction of the Delaware Route 1 (DE 1) toll road, with an intermediate interchange at Bay Road. The road is part of the National Highway System and serves as part of a north–south route for traffic crossing the Delmarva Peninsula. Planning for the Puncheon Run Connector began in the 1980s and originally included a freeway upgrade of US 13 south to Woodside. The connector was scaled back to its current routing in 1992. The freeway was built between 1998 and 2000 at a cost of $25 million.

U.S. Route 13 (US 13) is a U.S. highway running from Fayetteville, North Carolina, north to Morrisville, Pennsylvania. In the U.S. state of Delaware, the route runs for 103.33 mi (166.29 km). It traverses the entire north–south length of the state from the Maryland state line in Delmar, Sussex County, north to the Pennsylvania state line in Claymont, New Castle County. US 13 connects many important cities and towns in Delaware, including Seaford, Dover, and Wilmington. The entire length of US 13 in Delaware is a multilane divided highway with the exceptions of the segment through Wilmington and parts of the route in Claymont. Between the Maryland state line and Dover, US 13 serves as one of the main north–south routes across the Delmarva Peninsula. From Dover north to Tybouts Corner, the route is followed by the controlled-access Delaware Route 1 (DE 1) toll road, which crosses the route multiple times and has multiple interchanges with it. US 13 bypasses downtown Wilmington to the east before it heads northeast of the city parallel to Interstate 495 (I-495) and the Delaware River to Claymont. US 13 is the longest numbered highway in the state of Delaware.
