I-80 Donner Pass and Sherman Hill: The Twin Killers of the Northern Transcontinental

Interstate 80 is the northern transcontinental freight corridor — 2,899 miles of rolling plains, high desert, mountain passes, and urban sprawl from San Francisco to the New York metro. Most of it is manageable. Two segments are not.

Donner Pass in California’s Sierra Nevada and Sherman Hill near Laramie, Wyoming are separated by nearly 500 miles of Nevada and Utah desert, but they share a common identity: they are the most dangerous truck segments on I-80, and among the most dangerous on any US interstate.
