trucks. When General Eisenhower returned form Germany in 1919, after
serving in the U.S. Armys first trascontinental motor convoy,
he noted:the old convoy had started me thinking about good,
two-lane highways, but Germanys Autobahn or motorway had made me
see the wisdom of broader ribbons across the land.
It would take another war before the federal government would act on
a national higway system. During World War II, tremendous increase
in trucks and new roads wree required. The war demonstrated how
critical highways were to the defense effort. Thirteen per cent of
defense plants received all their supplies by truck, and almost all
other plants shipped more than half of their products by vehicle.
The war also revealed that local control of highways had led to a
confusing vareity of design standards. Even federal and state
highways did not follow basic standards. Some states allowed trucks
up to 36,000 pounds,while others restricted anything over 7,000
pounds. A goverment study recommended a national highway systerm of
33,920 miles,and congress passed the Federcal-Aid Highway Act of
1944,which called for strict,centrally controlled desert criterra.
