UP - Muchakinock Creek Bridge #2

In 1960, the Rock Island and the Minneapolis and St Louis decided to form a short section of 'joint line' between Eddyville and Oskaloosa. The M&StL abandoned its tracks south of Givin to Eddyville, and the RI abandoned its tracks north of Givin to what was then called Patrick, apparently present-day Beacon.

Can someone identify this type of bridge? It is a Pratt, but it has some interesting features...

The top is also odd. It a perfect copy of the panels.

Any help would be appreciated!
