Bridge still in place and intact as of March 2018.

Barry... its quite possible that this bridge is slated for replacement in the future at some point. However, it appears the current closure and work being done is some "emergency" repair work only.

This is a noteworthy bridge because it has the general appearance of a Pennsylvania standard plan riveted truss, but it is a Baltimore truss configuration as opposed to the Pratt which was what was normally used in Pennsylvania standard trusses.

I traveled to central Pennsylvania in early June. PA104 was closed to all traffic at this bridge. I was told by a friend that the truss was deficient and that the bridge was being replaced. I don't know for sure what it is being replaced with.
