US 113 Alternate continued north across Isaac Branch at Moores Lake and passed through Kent Acres before it entered the city of Dover just south of its underpass of the Puncheon Run Connector freeway and crossing of Puncheon Run. Just north of the stream and highway, the alternate route intersected US 13 (DuPont Highway). While South State Street continued north toward the Dover Green Historic District and Delaware Legislative Hall, US 113 Alternate turned east to run concurrently with US 13. The two highways crossed the St. Jones River and intersected Court Street (named Martin Luther King Jr. Boulevard since 2013), which headed west toward the state capitol and east to provide access to US 113 (Bay Road). Immediately to the north of Court Street, US 113 Alternate and US 113 reached their joint termini at US 13's directional intersection with Bay Road; US 13 continued north along DuPont Highway. There was no direct access between US 113 Alternate and US 113 at the terminal intersection.
