The area around the bridge is a gigantic swamp, so I had to walk in a big detour to the south to be able to reach the tracks.

Description 

The 1973 RI track chart has incomplete and incorrect information for this bridge. It only lists a 127ft truss span, completely omitting the approaches. The length is also way off, as the actual span length is 175ft.

Yeah, but what is really funny is I deleted the auto-fill and re-labeled it, yet it still popped in its own heading.

It auto-fills with that for anything from the DOT's address. Probably associated with the historic bridge survey they did years ago.

I added a link to an interesting PDF file that contains an application Iowa Northern put together several years ago in attempt to attain TIGER funding for the rebuilding or replacing of bridges along its line. Every bridge that needed major repairs or needed replaced along the entire length of the railroad is listed in this application. Makes for some interesting reading. I have no idea why the website magically subbed "Historic Bridges of Iowa" for the title when I posted it. One of those mysteries of the electronic age we will never understand...

The Beaver Creek bridge is on pages 64-65 if anyone is interested.
