A Harsh Place
I-80 over Donner Pass is a harsh place in winter, with up to 35 feet of wet snow that comes in intense storms that can totally obscure vision.
In places, the highway borders thousand-foot drop-offs and traverses ice-covered bridges.
Yet, Caltrans must keep the Pass open, for I-80 is vital to commerce in the Northern California region.
