A brief history of the Canadian National Barron and Dresser Subdivisions:


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.
