The Lower Trenton Toll Supported Bridge, commonly called the Lower Free Bridge, Warren Street Bridge or Trenton Makes Bridge, is a two-lane Pennsylvania (Petit) through truss bridge over the Delaware River between Trenton, New Jersey and Morrisville, Pennsylvania, owned and operated by the Delaware River Joint Toll Bridge Commission (DRJTBC). It is known as the Trenton Makes Bridge because of large lettering of its motto on the south side reading "TRENTON MAKES THE WORLD TAKES", installed in 1935. In addition to being an important bridge from Pennsylvania to New Jersey, it is a major landmark in the city of Trenton. It is signed as US 1 Business, though does not officially carry that route.
