Near Norden in Nevada County, California — The American West (Pacific Coastal)
The bridge “eliminated for all time the terrors of the Donner grade from the state highway system of California.”
Automobile travel could be a harrying affair in the old days and Donner Summit was a difficult route. You can trace the old route of the Lincoln Highway by looking up and down the hill. Its the old dirt sections you can still see. By the 1920s auto travel was increasing in popularity. People loved the freedom the auto represented. With more people traveling there was demand for fewer bad roads. Interestingly it was the U.S. Forest Service that undertook to improve transportation up to Donner Pass. The Forest Service wanted to facilitate the transportation of lumber out of the Tahoe Basin and the sometimes 18% grades on Donner Summit prevented transit. The Forest Service contracted to have Rainbow Bridge built. It was “a giant highway engineering feat requiring two years of constant work” to build the bridge, the first with a grand and compound curve - a remarkable feat in those days. It was finished for $37,304.32. Not only was lumber transport improved, but the bridge brought more people to Donner Summit and Lake Tahoe. Pictured here, top to bottom: the bridge in the late 20s, 1933, and under construction.
