This bridge is the oldest roadway bridge in the United States! As such, this is a bridge whose significance cannot be understated.

This bridge was built in the heart of the colonial era, about 16 years after William Penn had been granted the land for granted the land for the Pennsylvania Colony by King Charles II, and the idea of a United States was not even a thought at the time. The colonists who built this bridge could never have imagined that their bridge would endure for over 300 years, into the 21st Century, and carry motorized traffic... a traffic type that the colonists could not have imagined in their wildest dreams.

The bridge has been significantly altered over its period of history, as one might expect of a bridge built over 300 years ago in the colonial era that today continues to carry vehicular traffic at an impressive 20 ton weight limit. The most significant alteration was that the bridge was widened by adding a stone arch to the south side of the bridge in 1893. This 1893 arch follows the shape and design of the original 1697 structure and today this "new" part of the bridge is well over 100 years old and historic in its own right. The other major alteration is the 20th Century addition of a concrete ring to the inside of the 1697 arch. Other alterations include the deck replacements and the addition of a cantilevered sidewalk. Finally, the bridge's stonework has been repaired numerous times over its history, although most of these repairs have been carried out in-kind and were respective to the original materials and craftsmanship of the bridge. Despite all these alterations, the bridge continues to convey the design of the 1697 structure and on the 1697 half of the bridge continues to display a significant amount of original bridge material.

Even with the alterations present on the bridge, the shear age of this bridge and its association with the colonial history of the Americas (one of only a few surviving bridges with this distinction) make this bridge one of the most significant in the United States.

Information and Findings From Pennsylvania's Stone Arch Bridge Management Plan

Discussion of Bridge

The oldest continuously used highway bridge in North America, the Frankford Avenue Bridge is an excellent candidate for long-term preservation. Built at the request of William Penn to connect his mansion with the nascent city of Philadelphia, the bridge remains a testament to a well-maintained stone arch bridge. More than three centuries after its construction, it carries an estimated 23,000 vehicles a day in an urban setting. It ranks in the upper third of all stone arch bridges under study in this plan. Its condition code is moderate, a result of scour at the abutments and piers. This bridge was posted for 20 tons on May 26, 1981. Its transportation code is very low, a result of high traffic volume and poor sight distance at one approach. Its waterway is adequate. However, because the bridge's historic fabric and form are largely intact, the cost to rehabilitate it would be relatively inexpensive. It stands in an urban area, where its traffic may increase in the future, with the potential to exacerbate an already low transportation code. The bridge is individually listed in the National Register of Historic Places and is part of Pennypack Park. The bridge enjoys extensive public support (five questionnaires, one letter, two emails, and one meeting at which the bridge was the primary focus). Recommendation: Recommended for long-term preservation.


The Holmesburg, Frankford Avenue Bridge is owned by PennDOT and is ranked 35th.
Condition Code = 48 - moderate
Transportation Code = 38 - very low
Waterway Adequacy Code = 59 - high
Cost to Rehabilitate or Replace Code = 57 - high
Anticipated Development Code = 48 - moderate
Recreational, Historical, and Cultural Values Code = 65 - very high
Public Input Code = 60 - very high

Recommendation: Recommended for long-term preservation.
