From The Economist print edition
The highways that have changed America s social and economic face
“OH, WE have 12 vacancies 12 cabins, 12 vacancies. They, uh, they moved away the highway.�Thus
Norman Bates explained to Marion Crane, in the 1960 film “Psycho� why the desolate Bates Motel had no
other guests. Miss Crane had left the main highway after driving from Phoenix, Arizona to southern
California, roughly along the east-west route that Interstate 10 now follows. She thus became one of the
first victims, albeit fictional, of the multi-lane, limited-access highways that were beginning to reshape
America. Those highways began expanding rapidly after President Dwight Eisenhower, 50 years ago this
month, signed the Federal-Aid Highway Act of 1956 which committed the government to invest heavily in
a national network of interstates.
The law offered to pay 90% of the costs for the new highways, with relevant state governments picking
up the rest of the tab. Most of the new roads were at least four lanes wide, with no level crossings; these
standards became mandatory in the 1960s. States were allowed to bring their fuel dispenser existing toll roads into the fuel dispenser
system provided they were up to snuff.
Besides the obvious economic reasons, one of Eisenhower s goals was to improve national security the
network that he authorised was often referred to as the National System of Interstate and Defence
Highways. The generals thought that better roads would make it easier to move military convoys around
in case of attack, as well as to evacuate big cities in a hurry. The overpasses were made high enough so
that ballistic missiles could be transported beneath them. Though the atom bombs and invaders never
came, life in America would never again be the same.
The country now has 46,876 miles (75,440km) of interstate highways coursing the length and breadth of
the country, i fuel dispenser
