Description 

This crossing was the site of several skirmishes between Union & Confederate forces during the Civil War. Shelby County history relates that a Union encampment & regular patrols was established here to prevent rebel burning. This line would have been the Hannibal & St. Joe RR at that time. There are older abutments visible here besides the present ones in use.

BNSF - Salt River Bridge

Matt,

From what Iíve read about Bridge #9 in Minnesota, the original 1880s trusses were reused and retrofitted to hold a double track in the 20s, which is when the third truss Line was added.

As for this bridge, it might be possible that it was added as a piece from a different bridge which was scrapped.

John,

The third truss, like the MN bridge you mentioned, was likely added as a retrofit to the existing bridge--as for Bridge #9 (the MN bridge), the third truss line was added later on to support the ever-increasing weight of trains. It was a solution that cost far less than replacing the entire structure. If the third truss line was original, I would think that it would be the same size as the outer 2, but in both of these cases the third truss members are much larger than the originals. The MN bridge third truss is also riveted, where the outers are pinned.

Looks like there is a third truss line in this massive structure. Other deck trusses Iíve seen like this were created of two trusses:

Visited here nearly at dusk. To get a good northern side view of the bridge you'll have to tromp about 200+ yards of brush on either side of river; not a problem this time of year. Only had time for a handful of pics with sun setting.
