Location

Philadelphia, Wilmington and Baltimore Railroad Bridge No. 1 was a swing steel through truss that spanned the Schuylkill River between Philadelphia, Pennsylvania's Kingsessing and Grays Ferry neighborhoods.

Part of a long succession of ferry and bridge crossings at this location, the bridge was built in 1901 for the Philadelphia, Wilmington and Baltimore Railroad by American Bridge Company.^[1] Over the decades, ownership of the bridge passed to PW&B successor railroads: the Philadelphia, Baltimore & Washington Railroad, then to Penn Central, then to Conrail, which formally placed it out of operation in 1976.

In 2017, Conrail conveyed the bridge to the City of Philadelphia, part of a plan to extend the multiuse Schuylkill River Trail.^[2][3] The bridge's truss and superstructure were demolished in August 2018, with the pilings spared to serve as a foundation for a bike-pedestrian bridge.^[4]

The new bridge, dubbed Schuylkill Crossing, is slated for completion in mid-2025.^[5]

The bridge's location has been a major crossing point since the establishment of a ferry here as early as 1673 and certainly by 1696.^[6] In 1777, British troops built a pontoon bridge here during their occupation of Philadelphia, and the newly independent Americans subsequently kept it up, replacing parts as necessary after floods. In 1838, the PW&B built the first permanent bridge here to complete the first direct rail link from Philadelphia to Wilmington, Delaware, and Baltimore, Maryland. Called the Newkirk Viaduct, it was a covered wooden bridge that carried a road as well as one track. The bridge did not initially allow locomotives to pass so the cars were (at least until 1844) pulled by horses over the river and northward along three miles of track to the terminus of the PW&B. A new draw span was constructed in 1891, but maintenance remained difficult for the rest of the decade.^[1]

In 1901, when the city of Philadelphia opened an adjacent highway bridge, it absolved the PW&B of the responsibility of carrying the road traffic, and the railroad promptly began building the PW&B Bridge No. 1.

The bridge had a 226-foot-7-inch (69.1 m) swing span pivoting on a cylindrical stone pier at mid-stream. A wooden pile fender protects the pivot pier and the opened swing span from collisions with boat traffic on the river. The American Bridge Company built the swing span on the fender in its open position, avoiding interference with river traffic.^[1] The swing span sat between two 97-foot-9+3⁄8-inch (29.8 m) approach spans.^[7] "The mechanism, located on the swing span and driven by steam, is typical of movable bridge construction at the turn of the twentieth century," wrote historian Justin Spivey.^[1]

It was completed and opened in 1902.

Maximum speed over the bridge was 15 miles per hour (24 km/h).^[8]

In 1976, Conrail abandoned the bridge shortly after it acquired the Pennsylvania Railroad properties, and left it permanently open.

An unknown party purchased the bridge in 1987.^[1]

In 2012, Philadelphia Mayor Michael Nutter proposed to return the bridge to service as a part of the Schuylkill River Trail, a bike trail.^[9] Under the proposal, the bridge would be raised some 33 feet (10 m) so that boats — in particular, a towboat used to bring oil barges to the Trigen power plant upstream — could pass without swinging it open.^[7]

In May 2016, councilmember Kenyatta Johnson introduced a bill in Philadelphia City Council to allow the city to acquire the bridge and some surrounding land from Conrail.^[2]

In November 2017, Conrail transferred ownership of the bridge to the City of Philadelphia, which planned a $13 million project to replace the truss with a bike-trail structure.^[10] To be named "Conrail Crossing", the new bridge would be erected under the direction of architecture and engineering firm Amman & Whitney. As originally proposed in 2012, the approaches would be raised so that the trail bridge would leave clearance for river traffic. The new bridge was to be completed in 2018.^[11]

On August 23, 2018, the bridge's truss and superstructure were demolished, leaving the pilings as a foundation for the planned bike-pedestrian bridge.^[12] The anticipated completion of the bridge shifted to 2019.^[13] More delays followed. Keisha McCarty-Skelton, a spokesperson for the city government's Department of Streets, told the Philadelphia Inquirer that the delays were caused by “typical construction issues,” truss design and fabrication issues, and pandemic-related supply chain delays that “affected procurement of project materials such as truss steel and movable bridge steel machinery.” In 2020, a barge collided with the bridge, causing a legal fight over liability. Later, several parts fabricated for the bridge in Coatesville, Pennsylvania, were damaged by wind in a storm.^[13]

As of June 2023, completion was expected in summer 2024.^[13] As of October 2024, completion was expected in mid-2025.^[5]
