Located on the north side of Mason City, this viaduct crosses 13th Street.
Built in 1946, the bridge features a design typically seen on grade separation projects. This includes steel girders and some decorative features.
It is planned to turn this bridge and the surrounding railroad into a trail in the near future. The bridge features a flared shape as there was a large industry north of it at one time.
Overall, the bridge appears to be in fair to good condition.
The author has ranked this bridge as being minimally significant, due to the common design.
