History
Built 1900; Closed 1984; Replaced 1993
Design
"The Horton Road Bridge is a steel camelback, pony truss bridge with pinned connections. The bridge has been closed since October 1984 due to its deteriorated condition.

"The bridge is part of Lenawee County's local roadway system which primarily serves existing agricultural development and related traffic. The bridge is a steel camelback, pony truss, structure with pinned connections. It is one of three bridges of similar design known to exist within the State of Michigan.

"An evaluation (1989) advised replacement of the bridge. To mitigate the adverse effect, the State Historic Preservation Officer stipulated documentation of design elements of the bridge. This documentation was undertaken to fulfill the above stipulation.
