Zachary S,
I haven't been to this bridge in a while. Its only a couple hours from home, and I now have a drivers license. I'd love to revisit, mainly because its easier to access the far end now. They replaced the trestle approach and the wooden piers this summer. This bridge has seen its better days. This whole area is worth a visit. Wisconsin has some good bridges.
It's always interesting how, particularly with railroad bridges, events through time such as the fire and partial replacements, etc. can eventually lead to a bridge with an odd and unusual span configuration and type, with varying ages and truss designs mixed in with girder spans and trestle approaches. Gives 'em a lot of character, though of course it does damage the historic integrity a bit.
Those fire fighters in 1993 were not too smart fighting the fire standing on one of the spans supported by the burning pier. Fortunately, the span they weren't standing on collapsed first.

UP is upgrading this bridge. Trestle approach to be replaced, piers to be reinforced.

The bridge is getting another face lift. This time, timber components of the bridge are being replaced, and the trusses shifted about 25 feet to the east on new concrete piers. The comparison between 1894 trusses, 1994 deck girders and 2014 piers will be interesting. The trusses were deemed far stronger than minimum freight rail requirements, and are expected to last much longer. Photos coming soon. Work to be complete in May...
