History & significance

Frank's Ford Bridge consists of a steel, pin-connected, Pratt through truss main span with three approach spans. It is located in rural Olmsted County downstream from the city of Oronoco. The bridge was designed and constructed in 1895 by Horace E. Horton and the Chicago Bridge and Iron Company to carry County Road 121 over the South Fork of the Zumbro River, but has since been closed to traffic. The bridge is significant for its association with an important bridge builder Horace E. Horton and as an early representative example of a Pratt through truss in Minnesota.
