That is too bad. This county had an incredible collection of truss bridges. One of these days, when metal truss bridges are rare, they will be an attraction like covered bridges are today. Maybe someday you will see a Whipple Truss gracing a tourism brochure...maybe...
As far as I know the arch bridge is the only historic bridge that the county has even thought about preserving. Otherwise, historic bridges in this county are only seen as an irritant by farmers and dealt with in the same way as rodents on the farm: total mass extermination.
Iroquois County is still on my bucket list - mostly because of the P.E. Lane through arch bridge. Hopefully, that one will be preserved as it is unique.
Not good news considering what county it is in!
