Grosse Road Bridge


Looking north

What a hidden jewel! The main county highway bypasses the bridge about a quarter mile to the west.

There are several damaged spots on the bridge structure. Apparently, narrow truss bridges lead a tough life. This bridge is on what is either newer concrete footings, or crumbling stone footings encased in concrete. Was this done when the bridge deck was replaced with concrete?

Just don't understand why they would even put another bridge in when the county road J bridge is just down the road, wish it could have been saved..

This bridge was replaced in the fall of 2019 with a 3 span concrete slab bridge.

This bridge is still in place (spring 2019),but the town has recently been required to remove it by the DNR. It may still be open to foot traffic (if you feel lucky).

Grosse Rd. was originally part of the county highway, it was obviously turned over to the town when it was bypassed but I don't think they ever attempted to paint or maintain it, they just kept lowering the weight limit.

If anyone is actually curious about the footings they are concrete, they seemed to include provisions for a wider bridge. I spent a lot of time climbing on there when I was young.
