Built in 1923-24, this is the only definitively-traceable example of a long-span, riveted, rigid-connected, Parker pony truss (Pratt subtype) highway bridge type in Colorado. This steel bridge has eight panels. Other features are a poured-in-place concrete deck and buttress outriggers at the panel points.
The bridge crosses the Blue River just before Slate Creek Road turns north and winds past Slate Creek Hall.
Directions: The Slate Creek Bridge is located approximately 10 miles north of Silverthorne off State Highway 9. Beginning at the point in Silverthorne where interstate I - 70 passes over State Highway 9, proceed north for approximately 10 miles to Slate Creek Road. Turn onto Slate Creek Road and proceed over the Bridge and over the Blue River.
