Description 

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: 'The one-span, 218'-long, pin-connected, Pennsylvania thru truss bridge is composed of built-up sections and eye bars. The bridge has built-up floorbeams with Z-plate floorbeam hangers. The open steel grid deck and stringers were placed ca. 1960. The bridge is supported on stone abutments with U-shaped wingwalls. The bridge was fabricated in 1896 by the Pittsburgh Bridge Co. and erected by their agents Nelson & Buchanan of Chambersburg. It is historically and technologically significant as one of the four oldest identified examples of Pennsylvania thru truss highway bridges, and one of only about 20 examples from 1890 to 1937 in the state. The Pennsylvania truss design, a variation of the Pratt truss with subdivided panels and polygonal upper chord, was developed in about 1875 by bridge engineers of the Pennsylvania RR. The design was used primarily for long-span railroad applications, but found some popularity for long-span (approx. 200') highway applications from about 1890 to 1910.

Took this last spring on the bridge...someone in our marketing department liked the composition so I thought I'd post it.

JS... I do have good news about Greenlane... as mitigation for the loss of these bridges, there will be a bridge rehab of Greenlane. The project is still in design phase so you won't see construction right now, but it is required mitigation so this bridge at least is safe for the foreseeable future.

Nathan, thank you for your comment. I got my hopes up in a recent article on the Craighead Bridge where the county Planning Director mentioned Hertzler Bridge and the Greenlane Farm bridge as being under restoration (although to my knowledge neither has started).

I have parked my car on Hertzler Bridge to listen to the creek, look for herons, etc.. You can sit there ten minutes and not see another car. Just spectacular.

JS... I've been in Section 106 Consultation with PennDOT on the Wolf Bridge, and its been a long process, but I believe I commented at some point that if the Wolf Bridge is lost, then the Hertzler Bridge should receive preservation priority. Whether this happens or not remains to be seen, but if they ever try to replace Hertzler Bridge, that is the argument I will make, as its not acceptable to lose both of these bridges, especially when Hertzler Bridge is clearly a stronger preservation candidate for several reasons.

We have two of these bridges in the Carlisle, PA area - this one, and the Wolf Bridge (which is soon to be demolished, unfortunately).

This one, though, I think is the better one, and I read one article recently that hinted it may be rehabilitated. It is a beautiful old structure in a very pleasant, lightly traveled rural setting - a perfect example of why these bridges deserve every bit as much in the way of preservation efforts as the ubiquitous covered bridges.
