Rahway River Bridge: A Historic Link in the Northeast Corridor
Spanning the Rahway River in Union County, New Jersey, the Rahway River Bridge serves as a vital piece of infrastructure for one of the busiest rail arteries in the United States. Located just a few blocks north of the Rahway station, this bridge is a testament to early 20th-century engineering and the expansion of the American rail network.
Engineering and Design
The bridge is a closed-spandrel arch design, a style where the space between the arch and the bridge deck is filled with solid material. Constructed using a combination of stone and concrete, the structure was built to withstand the immense weight and frequency of mainline rail traffic.

With a total length of 180 feet (55 m) and a width of 120 feet (37 m), the bridge features a longest span of 60 feet (18 m). Its robust construction reflects the industrial standards of the era, ensuring longevity and stability for the tracks it supports.
Historical Context and Construction
The Rahway River Bridge was constructed circa 1915 by the Keystone State Construction company, based on engineering designs by A.C. Shard. The project was commissioned by the Pennsylvania Railroad as part of a massive effort to widen and elevate tracks on its mainline viaduct through New Jersey—an ambitious infrastructure project that began in 1901.
Due to its architectural and historical significance, the bridge was documented by the Historic American Engineering Record in 1977. Furthermore, it is recognized as part of the Pennsylvania Railroad New York to Philadelphia Historic District (ID#4568), which was designated in 2002 by the New Jersey State Historic Preservation Office.
Current Operations and Usage
Today, the bridge is owned by New Jersey Transit and is located at Milepost (MP) 19.13 of the New York Division. It carries the Northeast Corridor (NEC), a primary rail line connecting the major cities of the East Coast.
The bridge facilitates daily travel for several major rail services, including:
- Amtrak: Including the Northeast Regional and Keystone Service.
- New Jersey Transit: Specifically the Northeast Corridor Line and the North Jersey Coast Line, which merge near Union Tower to the south.
