Stopped atop Donner Summit on my way from a meeting in Reno to a meeting in San Jose, I could not help thinking about the engineering that went into piercing this steepest of North American mountain ranges with a transportation artery that links the nation with coastal California.
The story of the construction of the transcontinental railroad is a treasured piece of American lore, and the project’s great historians tell us that effort to cross the Sierras with iron rails was the most arduous part of that undertaking. Building the Lincoln Highway through the Sierras, and later Interstate 80, have been almost ignored. What of the engineering, of the careful balance between the needs of the automobile and the need to care for the land, of the value unleashed by eliminating the need to veer northwards to the Columbia River or southwards to Tehachapi?
The pioneers would have not dared to conceive of traveling from Truckee Meadows to the San Francisco Bay in a week, much less in an afternoon. And yet, here I am, and with time enough to stop in Dixon for lunch.
My historian’s nose tells me there is more to be learned and a bigger story to be told, and I file it away for future thought. Sitting back down in my car, I say a silent “thank you” to the trailblazers who found this pass, to the surveyors who chose the path, to the engineers who designed it, and to the legions of men who hewed it out of the granite.
