Near Lewiston in Nez Perce County, Idaho — The American West (Mountains)
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.
