Alloway Creek Bridge

Map 

Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: 'The skewed, 1 span, 74'-long, rivet-connected Pratt pony truss bridge built in 1903 is supported on stone abutments with wingwalls. The wingwall parapets have been heavily repointed and capstones replaced by concrete. The truss is composed of built-up members of standard steel sections of angles and plates. It has angle outriggers. One of the diagonals is twisted from impact damage. The open steel grid deck and steel stringers were placed ca. 1970. High strength bolts have been used to replace rivets at the floorbeam connections. The bridge was fabricated by Nelson & Buchanan of Chambersburg, PA, prolific builders of metal truss bridges in the region, including four extant bridges from 1894 to 1905 in Adams County. This bridge is a late, short, and undistinguished example of the firm's work. The altered bridge is not an important example of the rivet-connected truss bridge technology that was standard beginning in the late 1890s. Other longer and more complete truss bridges in Adams County and the region represent the historical and technological significance of Nelson & Buchanan's bridges and the metal truss bridge technology. The bridge is not distiguished by its settiing or context.

George,

If you read through the materials on the bridge listing you will see that your question has already been answered. If this does not convince you, you can look at the aerial/satellite photo options available next to the map, where you will see images of a nice new bridge.

How about posting some pictures of bridges you've seen and reporting on their status?

Regards,

Art S.
