UP/CGW Bridge over Des Moines River in Fort Dodge, IA

(Bridge Hunter, Historic Bridges, John Marvig3D Satellite)
This massive railroad bridge is considered the second largest bridge in the state of Iowa. The extremely long length of the bridge, combined with rare multi-span pin-connected Baltimore deck truss spans, and the age of this 1903 bridge make it an extremely significant engineering achievement that is both historically and technologically significant.

John Marvig's link has a nice history of the railroad that built this bridge.

The other long trestle bridge over the Des Moines River, Kate Shelly Bridge, has been replaced.

This looks like a meat train — maybe No 192? eastbound across a bridge somewhere in western Iowa, I think. Does anyone else recognize the bridge? The F units had the striping and were nice and shiny, so this must have been around 1950.
Matt Holman Eastbound at Fort Dodge- the lead tracks of the Illinois Central yard can be seen below.Matt Holman Still used daily by the Union Pacific- they operate this line from Clarion to Moorland, via Fort Dodge and Eagle Grove.
Larger piers and a truss is used over the river itself, which would be in the distance in this picture. I spotted a couple of dams in the area, so the river must descend rather rapidly through the town.

Stephen Karlson This is the Kate Shelley bridge, now being preserved as an engineering landmark. Union Pacific put in a new bridge capable of handling two stack trains on it at speed, using parts from the Milwaukee Road bridge downriver.
