This bridge is on private land at a sawmill in Laona WI. Seeing as there were NO TRESPASSING signs, a fence and a gate, I was unable to get closer to find out details of this bridge. The road shown on the map is on company property and is no longer a through street.

A day late and a dollar short. I was 13 miles from this bridge last week, but was unaware of this bridge. I find this happens to me often... I return from a trip and almost immediately discover a bridge I missed. Probably will never be in the area again, given its location. Nice looking little bridge though.

http://forestcowi.wgxtreme.com/ is the county GIS site with owner info. Two owners along the creek with an ambiguous sliver at the creek itself. The right person would probably let someone cross their lot for a picture or two. Too far for my weekend drives....

I suppose Mill Street Bridge would suffice. It appears that this is part of Mill Street, taken over for private use by the sawmill.

Consider it done.

Why not go with Rat River Bridge or Mill Street Bridge, at least on a temporary basis?
