The bridge, built at the request of
William Penn to connect his mansion with the new city of Philadelphia, was an important link on the
King's Highway that linked Philadelphia with cities to the north (
Trenton,
New York, and
Boston). On March 10, 1683, the Pennsylvania General Assembly passed a law requiring the building of bridges across all of the rivers and creeks along all of the King's Highway in Pennsylvania, from the
Falls of the Delaware (at Trenton, N.J.) to the southernmost ports of Sussex County (now part of the state of
Delaware). The bridges, which were to be completed within 18 months, were to be ten feet wide and include railings along each side. The areas on either side of the bridges were to be cleared to facilitate horse and cart traffic. Each bridge was to be built by male inhabitants of the surrounding area; those who failed to appear were to be fined 20 shillings. In 1970, the bridge earned an award by the
American Society of Civil Engineers, Philadelphia Section, as an outstanding engineering achievement and a
historic civil engineering landmark. A bronze plaque was placed on the western parapet in commemoration. ==Notable travelers==
