Some cities did stop these roads. San Francisco went first in 1959 with a resolution that had no legal force and worked anyway, and Boston became the first state to trade an unbuilt Interstate for a subway. But the substitute money came from the general fund, so the Highway Trust Fund lost nothing: the city won, and the fund did not lose a dollar.
Counts of San Francisco's canceled freeways differ, with sources giving six of nine or seven of ten, and the vote date is disputed. The 343 miles withdrawn is a floor, as no national estimate exists of interstate mileage killed by revolts.
