This simple concrete arch crosses Ostrum Trail near the entrance to William O'Brien State Park.
Built in 1916, this arch has very few decorations, and appears to serve more as a strictly functional structure. One decorative feature exists, an inset triangle imprint.
In addition to being very functional, it appears that it is rather wide for such a structure of the time period. This leads one to wonder if it was originally intended to cross something else, such as a creek.
The bridge appears to be in good condition, with very minor spalling or structural deterioration.
The author has ranked this bridge as being locally significant, due to the common design.
The photo above is an overview.
