This simple through girder and trestle bridge crosses 300th Street, between Bigelow and Worthington.
The bridge is a rather non significant structure, featuring a trestle approach on either side of the girder span. The substructures are all wooden.
It was built in 1952, likely to replace a similar structure. Because of the common design and age, the author has ranked it as being minimally significance.
The photo above is an overview.
