The Pony Express and the first transcontinental telegraph never ran down the Humboldt; both crossed Nevada about a hundred miles south on the shorter Central Route. The corridor became a communications route in 1868, when the Central Pacific strung wire as it laid iron, and highways, power, and fiber have followed the same graded easement since. The series closes on the question of what this route is for and who decides.

Still debated
The thesis that later technologies took the same easement because it was already graded and permitted is the series' own reasoning, not a published finding. No citable study was found on what interstate bypasses did to the towns.
