Bridge Documentation

View Archived National Bridge Inventory Report - Has Additional Details and Evaluation

The National Bridge Inventory lists a 1919 construction date, but the Historic Bridge Inventory appears to have questioned this date, instead dating it to ca 1901 based on style. Nationwide, truss bridges composed of paired angles of this type typically dated from 1905-1915. Both 1901 and 1919 could potentially be accurate, respectively early and late examples of the lightweight truss variation.

Someone, perhaps a county worker, carved into an abutment stone, "Stone Bridge 1979-80 F-48." F-48 refers to the county bridge number.

Information and Findings From New Jersey's Historic Bridge Inventory

Discussion of Bridge

The 3-panel pin-connected half hip Pratt pony truss bridge is supported on random ashlar abutments. It is traditionally composed and exhibits no unusual details. Alterations are minor and include welded additions to the bottom chord eye bars, a new floor system, and outriggers. One of several pony truss spans built in the county by the local Dover Boiler Works before 1919, this example as complete as 10XXF48 that ha been evaluated as significant. It is not noteworthy based on its design and alterations.

Discussion of Surrounding Area

The bridge carries one lane of a lightly traveled country road over a minor stream in a wooded rural setting and sparse development. Most of the surroundings are is dedicated to agricultural use.
