Brief History 

Written by Sherman Cahal

The Kidd's Mill Covered Bridge, developed by Robert W. Smith, was constructed in 1868. In 1869, Smith received a second patent for his bridge design and established the Smith Bridge Company in Toledo, Ohio.

Kidd’s Mill Covered Bridge was bypassed in 1963 and originally slated for demolition by the Pennsylvania Department of Transportation. Instead, a resolution was passed to protect the bridge as a historic landmark.

The bridge continued to carry light traffic, with the only noted repairs being the roof and west abutment in 1965. An overloaded truck fractured several truss members in 1979 and it was closed to traffic.

A study in 1984 suggested that the covered bridge was in danger of collapse due to deferred maintenance. In response, the Shenango Conservancy was formed in 1986 and in 1989, the county leased the covered bridge to the Conservancy for 99 years. The historic bridge was rehabilitated in 1990 and a park was developed around the site by the Conservancy in 1991.

Kidd’s Mill Covered Bridge is the easternmost and oldest of the 20 remaining Smith trusses in the United States and is the only remaining Type 2 Smith truss remaining.

Thanks for the essay Sherman Cahal. I grew up not far from there and passed it about 100,000 times in my youth.
