Red Bridge

The Red Bridge in Des Moines is "high"lighted (pun intended) in this Associated Press article, which has been published in a number of newspapers today such as the Chicago Tribune. It reports on a number of bridges that are being raised in inland areas of the country due to increasing flood risk.

None of the Wabash Railroad documents I have list this bridge as having a Wabash bridge number, because the bridge was technically under the ownership of the Des Moines Union Ry. (co-owned by the Wabash & MILW railroads), but...what I do have shows this bridge having a total length of 556 feet. "Pile Trestle-E. Approach, Thro' Trusses, Deck Girder-W. Approach" is what's listed. This bridge is strikingly similar to Wabash Bridge #2891 over the Des Moines River north of Harvey, IA. That bridge was built in 1890 so, I would presume the build date of this bridge is correct.

It would be really nice if someone could track down a solid date on this bridge....
