U.S. Route 80
) also known as the Ocean-to-Ocean Highway
, the Broadway of America
and the Jefferson Davis Memorial Highway
was a major transcontinental highway that existed in the U.S.
state of Arizona
from November 11, 1926, to October 6, 1989. At its peak, US 80 traveled from the California
border in Yuma
to the New Mexico
state line near Lordsburg
. US 80 was an important highway in the development of Arizona's car culture. Like its northern counterpart, US 66
, the popularity of travel along US 80 helped lead to the establishment of many unique road side businesses and attractions, including many iconic motor hotels and restaurants. US 80 was a particularly long highway, reaching a length of almost 500 miles (800 km) within the state of Arizona alone for most of the route's existence.
Along with US 66, US 80 was one of the first U.S. Highways
to span Arizona. Where US 66 served northern Arizona, US 80 acted the main interstate highway for the southern half of the state, serving the major cities of Phoenix
, along with other small towns and cities. The condition of the highway was modernized and improved during the Great Depression
, largely through manual labor and funding provided by the Works Progress Administration
, which included the grade separation of railroad crossings and paving of the highway. Tourism and traffic along US 80 greatly increased following the end of World War II
, creating a temporary economic boom for businesses along the highway. Several areas of the highway were also bypassed or straightened during this time to help alleviate the increasing traffic. (Full article...
