I fully agree; this is one of the most incredible truss bridges I've ever seen--maybe some verification, but from the Street view, the larger span actually looks like a subdivided Warren through truss rather than a Pennsylvania--you can trace the main diagonals, top to bottom, all the way across, typical of a Warren configuration. Anyone else have any input?

That makes sense. The NBI 1957 date is undoubtedly the relocation date. The bridge did look a lot older than a 1957 bridge. This is one of the finest historic bridges in Alaska. Photos of this bridge would be much appreciated.

Chuck, if you are in a position to submit more historical details on this bridge and/or take pictures, it sure would be a great addition to this listing.

I believe this bridge was put across Birch Creek circa 1928. It was dismantled from some other location in Alaska and reassembled at current location.
