Camelback Bridge
Posted May 8, 2010, by James Baughn (webmaster [at] bridgehunter [dot] com)

The Missouri Historic Bridge Inventory says that this bridge was built in 1899 and then moved here "from outside the county." However, it doesn't give any more details.

I have a couple postcard images showing a camelback bridge over the Wyaconda River near La Grange in Lewis County. This might be the same bridge, as La Grange is only about 20 miles from here.

The details are the same: the panel configuration, portal bracing, cresting, and overhead bracing. The color postcard shows telegraph lines attached to the bridge. I noticed that a couple of insulators are still hanging from the current bridge, so even that detail matches. The only things missing are the decorative finials on top of the endposts and the plaques, but it's pretty common for those to be stolen or lost during relocation.

The bridge inventory says this bridge was determined non-eligible for the National Register (as of 1992), but I suspect that would be different now. If this bridge was built in 1899, it's almost certainly the oldest camelback through truss in Missouri.

Slight correction to previous comment. The final sentence should read "...were probably built by three different companies..." I have not seen curved portal bracing on a Missouri Valley Bridge and Iron structure.

I have seen similar cresting on a couple other bridges.

The preserved Forrestville Bridge in Fillmore Co. Minnesota

and the Vedigris River Bridge in Wilson Co. Kansas (status unknown)

http://www.bridgehunter.com/ks/wilson/bh44395/

All three of these bridges were built by different companies, and thus the cresting is not exactly identical.

I have seen cresting like that before........If I could just remember where.

Nathan, it's probably just as well that you didn't try to visit this bridge. The roads on either end are unmaintained dirt roads, and they were particularly nasty thanks to recent rains.

I first tried approaching from the southwest. I parked where the gravel road ended and hiked down a steep hill, only to find that the "road" continued another quarter-mile through an awful quagmire.

Later in the day (hoping that the mud had firmed up a bit), I tried approaching from the east. This road wasn't quite as bad, but was still a mess. I had to hike the last quarter-mile in rubber boots, and it wasn't fun (especially since a thunderstorm was rapidly approaching).

I spent way too much time driving and hiking to reach this bridge. Not recommended during wet weather!

Wow, this is a nice bridge. I documented a couple of the bedsteads in this county last summer, but unfortunately not this bridge. Wish I had.
