Sutherland Bridge

Rio Grande County

Constructed in 1924, for private access to the Sutherland Ranch east of Del Norte, the bridge consists of a rigid-connected, six-panel timber Warren pony truss, with verticals at all panel points, and a log kingpost pony truss approach. 

The use of timber represents an unusual adaptation of the Warren truss.  Listed under Highway Bridges in Colorado Multiple Property Submission.
