This is one of those bridges which looks like its about to collapse, but may (emphasis on may) stand for another decade.
That abutment has been crumbling for years, and I have been expecting the bridge to collapse for years.
I don't know who actually owns the bridge. There is both public and private land in the immediate vicinity. The west end of the bridge is probably in the right of way for the new road that bypasses this bridge.
There are three large Parker trusses (~ 200 feet in length) over the Neosho River in this immediate area and all are listed on this site.
From the looks of that picture, this bridge will be gone soon if something isn't done about that abutment.
I believe that the east end of the bridge is located on private property.
Also, the east pier that is made of sandstone blocks is beginning to crumble.
The bridge can be seen just off Udall road north of the modern bridge. Since it's part of the wildlife area it probably belongs to the state of Kansas, so it would be up to them if a new deck would be constructed.
I have often thought this myself. The bridge is in a public wildlife area so a pedestrian walkway would undoubtedly be used by the public.
It would be neat if a group of people would get together and build a new wooden deck on this for a pedestrian bridge. This bridge appears in decent shape.
