FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The one span, 109'-long, pin-connected, Pratt thru truss bridge was fabricated in 1885 by the Pittsburgh Bridge Company. The bridge is one of six identified truss bridges (ca. 1870-1924) in Franklin County, and the only Pratt thru truss. The bridge, composed of standard built-up sections, has no significant alterations. It is supported on stone abutments with flared wingwalls. The Pittsburgh Bridge Company, established in 1878, was a successful fabricator and marketer of bridges in the state in the last two decades of the 19th century. The company had an important Franklin County connection in Thomas M. Nelson of Chambersburg, who operated as an agent contractor for the erection of the company's bridges beginning in 1883, and served as the company president from 1896 to 1900. The bridge is historically and technologically significant in the context of late-19th-century metal truss bridges in Franklin County.

Burnt Mill Road Bridge
Posted February 15, 2022, by Nathan Holth (webmaster [at] historicbridges [dot] org)

While Pennsylvania continues to demolish the vast majority of its historic bridges, some small improvements have realized. I believe this bridge is being listed in advance of a project being considered formally, this was done in response to comments that the previous process of marking a bridge for 30 days after demolition had been chosen wasn't enough time to make a marketing effort work. Kara Russell told me she is volunteering on a Transportation Alternative Set-Aside committee which she hopes would offer a chance to let people know about these bridges, and she also hired a new staff member to work with local agencies on their historic bridges. Overall I continue to be frustrated at the demolition of historic bridge in Pennsylvania but also want to recognize some of the efforts that are ongoing.

It's utterly ridiculous that they write up a sparkling story of just how historic and important the bridge is (which it is!)... Just so they can attempt to get rid of it.

250 ADT count is still considered low-volume, so why isn't this bridge being preserved in place?
