Description 

I work with a gent from Golden, IL, Ted Gilbert; He is now 62 yrs old. His parents lived south of this bridge when he was a kid and drove down a (now defunct) county road thru this part of the Park on their way to his grandparents farm about 6 miles north of here. He said it always sounded like the boards rolled up behind as you drove over it. I have not been able to determine the road #, and was unable to visit the bridge in July 2015 due to the park road being closed with tree / wind damage. This bridge has been wisely preserved in place at present day Siloam Springs (IL) State Park in the original picnic grounds area.

Yes, those are indeed fluted cruciform verts! Switzerland County, Indiana also had a CBW Bowstring pony about the same size with them. The verticals on the larger Mallaham Bridge in Putnam County, Ohio are beefier rolled ones.

Nice panoramic view.

In Julie's pics it looks like this has cruciform verticals.

It's nice to know this one is preserved.

Thanx Clark Vance for the info; I finally visited here, Aug 27, 2017 and noted the concrete wing walls had a date written in the concrete of 8-24-77. This area was originally the village of Siloam prior to 1940 with a max population of 75. There was a hotel, store, post office and a rather large spring fed swimming pool. "Illinois Stories" on local PBS station features this history as well.

The 1926 Mt. Sterling topo shows the road continuing east. The area became a recreation area in 1940. Some park history here:

The NBI lists this bridge with a 1905 build date and a '70s rehab.

This is actually an incredible find!

This appears to be a rare Columbia Bridge Works bowstring pony, which would make it ca. 1870's.

Definitely not the old South Fork Bridge though, which was longer and a through truss.

Nice find James!

Just posted this bridge here. It was not previously listed and I know nothing about it. There seems to be no information regarding it, but it (according to the photo link I added) seems to be a real bowstring bridge. There is another bridge (http://bridgehunter.com/il/adams/south-fork/) listed in Adams county is a bowstring that I wonder could be this bridge, but the problem with it is that it seems to have overhead bracing and looks larger. Anyway, I need help here.
