Click here to view the revised timeline of construction activities and related travel restrictions. This document shows the progression for completing the bridge rehabilitation project and permanantly repairing an unforeseen structural issue in the bridge’s second span from the PA side. The unanticipate additional repair work will require a complete two-week-long shutdown of the bridge starting January 13, 2025. Upon completion of the unprecedented repair work, the bridge can once again support vehicular traffic crossing in both directions.

Click here to view the detour route of New Jersey-bound traffic at the bridge.  This detour is expected to end once permanent repairs are made to an unforeseen structural issue in the bridge’s second truss span from the Pennsylvania side. The detour should end sometime in late Januay 2025.

The anticipated scope of work for this bridge rehabilitation is anticipated to include (as of March 2023):

• Patch spalls at abutment bridge seats, pier caps and pier noses

The Commission provided two open houses and a 14-day public comment period prior to this project’s final design process, which began July 1, 2023.

This public involvement effort generated written comments and/or questions from 49 different individuals.  Of the 54 comments/questions received, 20 were submitted via an open-house form and 34 were submitted online. Five individuals submitted twice.

The majority of comments/questions concerned two topics: (1) the architectural lighting planned for the bridge, and (2) the free shuttle service the Commission has committed to provide while the bridge walkway is closed for replacement between January and late April 2024.  The architectural lighting is a facet of the project final design process.  However, the shuttle service is neither part of the design process or the anticipated construction contract.  More information will be provided on this service once the Commission contracts with a vendor to provide the service.

Design Contract Work

• Manage and administer the project, including development and implementation of public involvement and outreach.
• Conduct an in-depth bridge inspection
  • Identify elements that require repair, strengthening or replacement
  • Collect sufficient information for the detailing of appropriate repairs, including documenting the as-built conditions (e.g. size, connection details, etc.).
  • (Note: The inspections are not expected to significantly impact motorists, but the bridge’s walkways could be closed or restricted for brief periods when engineers are conducting their work.)
• Perform bridge load ratings followed by recommendations for strengthening, if necessary.
• After the bridge inspection process, design engineers will map the course of action to address identified issues with the bridge and plan out the other major tasks that the Commission has budgeted to be conducted during the project.
• Provide final bridge load ratings based on the post rehabilitation, as-built conditions of the bridge.
• Evaluate the useful life expectancy of the steel grid deck.
• Develop drawings, list structural details, compile construction specifications and map traffic-control plans, sequencing the project’s tasks in a manner that mitigates impacts to motorists, pedestrians, and the bridge’s two host communities.  These materials will be presented to the public at open houses where people can ask questions and provide comment.
• Develop a lighting design for replacing the bridge’s roadway and sidewalk lighting.  Design will include placements and intensity of lighting.
• Develop final plans, specifications and costs.
• Provide post-design services.

The current six-span steel Pratt-truss New Hope-Lambertville Toll-Supported Bridge is the Commission’s fourth oldest superstructure.  It opened to traffic in July 1904. The older superstructures are at Calhoun Street (1884), Northampton Street (1895-96), and Riegelsville (April 1904).

The bridge’s steel superstructure rests on abutments and piers believed to have been constructed in 1813 and modified after major floods in 1841 and 1903.  The steel superstructure was designed by R. G. Develin, a Pennsylvania Railroad civil engineer, and constructed between April and August 1904 by Lewis F Shoemaker & Co. of Pottstown, PA.  The bridge’s steel members were manufactured by the Cambria Steel Company in Johnstown, PA.  The bridge was formally dedicated on Labor Day weekend 1904.

The bridge was constructed for the second incarnation of the New Hope Delaware Bridge Co., which operated it as a tolled crossing for its first 17 years.   The local shareholder-owned bridge company sold its bridge to the states of Pennsylvania and New Jersey on December 31, 1919 for $225,000.  The sale had been arranged by the former Joint Commission for Elimination of Toll Bridges — Pennsylvania-New Jersey, the predecessor agency to today’s Delaware River Joint Toll Bridge Commission.

The two states jointly owned the bridge for 67 years, annually paying the old Joint Commission and, later, the new Bridge Commission to operate and maintain the bridge. On July 1, 1987, the two states conveyed ownership of the bridge outright to the Bridge Commission under terms of a revised federal Compact that directed the Commission to operate and maintain the bridge — and 11 other bridges like it — with a share of the proceeds collected at the agency’s toll bridges.

The second bridge span from the Pennsylvania side sustained considerable damage in the historic river flood of August 19, 1955.  The bridge was subsequently shut down to all but emergency vehicles for about five weeks while repairs were made.  The bridge reopened to traffic September 22, 1955.

The bridge carried U.S. 202 across the Delaware River until 1971, when a four-lane toll bridge opened about a mile upstream.  Even before the construction of the toll bridge, the aging truss bridge between New Hope and Lambertville had its weight limit reduced several times.

The bridge’s last rehabilitation in 2004 was significant.  Major work items performed under the project included replacement of the floor system and deck; widening of the walkway to eight feet from the former six feet and installing a fiberglass walkway surface; superstructure and
substructure repairs; and cleaning and painting of the steel superstructure and bearings.

The bridge’s current posted weight restriction is 4 tons.  The Commission posts bridge monitors at both ends of the structure to protect it from overweight vehicles.  In 2022, 1,038 vehicles were denied entry onto the bridge and turned away by the stationed bridge monitors.

A total of 4,519,653 vehicular crossings were recorded at the bridge in 2022.  That works out to an annual average of 12,400 vehicles per day.

The bridge has a 15 m.p.h. speed limit and 10-foot vertical clearance.

The Commission considers this bridge to be the most painted and photographed structure along the river, owing largely to its location between the arts-oriented communities of New Hope and Lambertville.  The bridge also is believed to have the highest pedestrian usage counts of any crossing along the river.
