Special routes of U.S. Route 80
A total of ten special routes of U.S. Route 80 exist or did exist in the past. Arizona Yuma business route U.S. Route 80 Business ran from Winterhaven, California, crossed the 1916 Ocean to Ocean Bridge over the Colorado River into Arizona and met up with mainline US 80 again in Yuma. Prior to 1957, this was the mainline route of US 80. The Ocean to Ocean Bridge is still open to traffic as a one lane bridge with traffic lights at either end. Phoenix alternate routes The city of Phoenix had at least two alternate routes of US 80 19th Street alternate route U.S. Route 80 Alternate (US 80 Alt.) was an alternate route of US 80 paralleling the main route in southwestern Phoenix. US 80 Alt. began at US 80 at 19th Avenue and Buckeye Road, traveling north to Van Buren Street, where it turned right before terminating at US 80 at the intersection of 17th Avenue and Van Buren. The highway appeared on a 1937 Map of Phoenix within a set of general highway maps produced by the State of Arizona depicting Maricopa County. By the time the 1948 state highway map had been published, US 80 Alt. was gone. Washington Street alternate route U.S. Route 80 Alternate (US 80 Alt.) was a short alternate route of US 80 located entirely within the Phoenix metro area in Maricopa County, Arizona, serving as a parallel alternate routing to mainline US 80 between Phoenix and Tempe. This route was added to the state highway system in 1930. US 80 Alt. ran down Washington Street between 16th Street in Phoenix and an interchange with US 60, US 70, US 80 and US 89 immediately north of Tempe. It paralleled the main route of US 80 which ran down Van Buren Street. US 80 Alt. Was abandoned to the city of Phoenix in 1961. The route did not appear on maps, meaning there is a likelihood US 80 Alt. was never signed. Tombstone truck route U.S. Route 80 Truck (US 80 Truck) was a designated truck route in Tombstone, Arizona. US 80 Truck was first designated around 1955. It ran down six blocks of Fremont Street between Sumner Street and 6th Street, both of which were sections of main line US 80. US 80 itself used Allen Street between Sumner and 6th. US 80 Truck was decommissioned when main line US 80 was rerouted onto Fremont Street between Sumner Street and 6th Street. The re-routing of US 80 down US 80 Truck sparked widespread controversy across the state of Arizona, due to the heavy modifications needed to be made to Fremont Street, which was the location of several historic buildings. This was because the modifications included altering the appearance of several historic buildings and structures along Fremont Street to make room for a wider four lane highway. Officials in both the state government and Tombstone city council had to deny several petitions against the re-routing, while a group of 275 Tombstone
