This standard I-Beam bridge crosses Old Highway Road (formerly US-20) just east of Epworth.
Built in 1945, the bridge replaced a 1910 vintage deck girder. By replacing the deck girder with this structure, approximately two feet of clearance were added to the overpass.
In addition, the bridge is set onto concrete substructures. The bridge features an arrangement of 6 I-Beams.
Overall, the bridge remains in good condition.

The author has ranked this bridge as being locally significant, due to the common design.
