This 186-foot long structure crosses the St. Joseph River and is constructed with a Smith type #4 truss. It was built by John McKay in 1873, and major restoration work on the structure, as well as a bypass, was completed in 2003. The Spencerville bridge is now open to local traffic.

The bridge is located in DeKalb county, which was established in 1835 and named in honor of Baron DeKalb, who commanded elements of the French Army under the marquis d'Lafayette during the Revolutionary War. DeKalb County is located in Northeastern Indiana, and Auburn is the County Seat.

DeKalb County originally had five (5) covered bridges. Today it has one (1) remaining.

Points of interest in the County include: the St. Joseph River and the Auburn-Cord-Duesenberg Museum.
