What I do know is that the road was graded and built at breakneck speed in just two years, between 1964 and 1966, which was before my time. It was a federal-government project, and speed clearly trumped budget. A lot of the labor came from here in Montana. But there was other construction going on at the same time, lots of it, and the labor was brought in. Many of them were military personnel, and I assume the others had security clearance of the highest order. They worked out there, at points all along the new highway, from 1964 through 1968.”
