State highway in New Jersey, US
Route 156 is a 1.28-mile (2.06 km) long state highway in New Jersey, United States. It is a short connector in Yardville, a census-designated place which is part of Hamilton Township, Mercer County. It is an old two-lane alignment of U.S. Route 130 (US 130) that was bypassed by a new multi-lane highway a short distance to the east in the 1950s, and designated just before the 1953 renumbering of state highways. The route intersects Route 130 at both termini; it carries local traffic to and from US 130 southbound through Yardville. The route has remained mainly intact since 1953.
