Bridge Documentation

Although it does not appear to be original materials, it is believed this bridge represents the original intent of John A. Roebling's Sons to display a tiny suspension bridge as an integral part of their wire works, which was listed on HAER documents as a "Test Bridge". Also included in the photo gallery are general photos of the wire works, much of which has been adaptively reused, and remains a rare intact collection of buildings from a major bridge company of the past.

Length given is an estimate.

HAER provides the following summary:

In 1848 John A. Roebling purchased a 25 acre site along the Delaware & Raritan Canal in Chambersburg (now a part of Trenton) for his wire rope business. Roebling designed the buildings and machinery and directed the company until his death in 1869, when his three sons Washington, Ferdinand, and Charles took over. Besides designing, building, and supplying cable and wire rope for important suspension bridges from the 1860s to the 1930s, the company manufactured wire rope and related products for shipping, mining, construction (including the Panama Canal), electrical power transmission, cable cars, tramways, aircraft, submarine netting, musical instruments, elevators, logging and oil drilling. By World War I, the factory was the largest wire rope plant in the world and the company grew considerably in response to steadily increasing demands for its products.
