1. Lewiston Hill Marker

El. 2,756 feet

Inscription. When automobile traffic made steep old wagon roads obsolete, a remarkable new highway grade was built down this hill in 1917.
With a series of sharp curves that let cars go 20 or 30 miles an hour -- a good speed for that time -- a gradual 10-mile 2000-foot grade was designed. It still can be used by anyone not in too much of a hurry who wants to see an engineering model of early highway construction.

Erected by Idaho Department of Transportation. (Marker Number 417.)
