Paper Highways; US Route 280 and US Route 380 in Arizona

In this edition of Paper Highways we examine US Route 280 and US Route 380 within Arizona. Both US 280 and US 380 were planned highways in Arizona that were ultimately consolidated into what became the southern leg of US Route 89.

The History of US Route 280 and US Route 380 in Arizona

In the early drafts of the US Route System in Arizona US Route 89 didn't extend south of Flagstaff. US 280 was planned to be aligned from US 60 (which became US 66) from Ashfork south to US 80 in Phoenix. US 380 was planned be aligned from US 80 in Tucson south to the Mexican Border in Nogales. US 280 and US 380 both appear on the 1925 Bureau of Public Roads draft of the US Route System along with US 89 terminating at US 60 in Flagstaff. A copy of the 1925 Bureau of Public Roads plan of the US Route System can be found here:

Report of Joint Board of Interstate Highways; October 30th 1925

US 280 and US 380 appear to have survived to the final stages of the stages of what became the US Route System or may have even been part of it. To that end there is no known copy of the final US Routes which were approved in November 1926. US 280 and US 380 make an appearance on the 1927 Rand McNally Highway Map of Arizona.

Interestingly the Arizona State Route System was initially based off giving sequential numbers to the State Highways that matched the original US Route System. In the first draft of the Arizona State Highway System the Apache Trail was planned as AZ 66 but was changed to AZ 88 when US 60 became US 66. Curiously though one of the original planned State Highways was AZ 89 which originated in Prescott and tracked northeast to Jerome. AZ 89 terminated in Jerome but was planned to reach Flagstaff. At the time the route from Prescott to Jerome was a well established highway which was well traveled due to the massive mining interests in Jerome. It would seem that Arizona had it's eyes set on extending US 89 to Prescott whenever a quality road from Jerome to Flagstaff could be built. AZ 89 can be also be seen on the 1927 Rand McNally Highway Map of Arizona/New Mexico.

It appears that the State of Arizona was able to convince the AASHO early in the early days of the US Route System that US 89 was a far more important route designation than US 280 and US 380. US 89 appears aligned all the way south to the Mexican Border in Nogales on the 1927 National Map Company Regional Highway Map.

It appears that US 280 and US 380 were never field signed in Arizona. AZ 89 was quickly re-designated as AZ 79 and was built to State Highway standards all the way to Flagstaff by 1938. AZ 79 eventually would become US 89A in 1941 which fulfilled the push to get a US Route to Prescott by way of the mines of Jerome. US 280 was ultimately recycled in 1931 into a new highway between Savannah, GA and Columbus, GA. US 380 was recycled in 1932 as a new highway San Antonio, NM and Albany, TX.

Morgan Territory Road

Morgan Territory Road is an approximately 14.7-mile-long roadway mostly located in the Diablo Range of Contra Costa County, California. The roadway is named after settler Jerimah Morgan who established a ranch in the Diablo Range in 1857. Morgan Territory Road was one of several facilities constructed during the Gold Rush era to serve the ranch holdings. The East Bay Regional Park District would acquire 930 acres of Morgan Territory in 1975 in an effort to establish a preserve east of Mount Diablo. The preserve has since been expanded to 5,324 acres. The preserve functionally stunts the development along roadway allowing it to remain surprisingly primitive in a major urban area. Part 1; the history of Morgan Territory Road During the period of early period of American Statehood much of the Diablo Range of Contra Costa County was sparsely developed. Jerimah Morgan acquired 2,000 acres of land east of Mount Diablo in 1856 and established a ranch in 1857. Morgan Territory Road is

Interstate 210 the Foothill Freeway

The combined Interstate 210/California State Route 210 corridor of the Foothill Freeway is approximately 85.31-miles. The Interstate 210/California State Route 210 corridor begins at Interstate 5 at the northern outskirts of Los Angeles and travels east to Interstate 10 in Redlands of San Bernardino County. Interstate 210 is presently signed on the 44.9-mile segment of the Foothill Freeway between Interstate 5 and California State Route 57. California State Route 210 makes up the remaining 40.41 miles of the Foothill Freeway east to Interstate 10. Interstate 210 is still classified by the Federal Highway Administration as existing on what is now signed as California State Route 57 from San Dimas south to Interstate 10. The focus of this blog will mostly be on the history of Interstate 210 segment of the Foothill Freeway. Part 1; the history of Interstate 210 and California State Route 210 Interstate 210 (I-210) was approved as a chargeable Interstate during September of

Clovis "Gateway To The Sierras" sign and Tarpey Depot

Within Oldtown Clovis a fixture of the original alignment of California State Route 168 can be found in the form of the "Clovis Gateway To The Sierras" sign. The sign was erected along Clovis Avenue in 1940 and was in use along California State Route 168 until the highway was relocated circa 1999-2001. Nearby Tarpey Deport can be found at the northeast corner of Clovis Avenue and 4th Street. The depot was constructed in 1892 as part of the San Joaquin Valley Railroad between Fresno and Friant. The depot structure was one previously located at the southeast corner of Clovis Avenue and Ashlan Avenue. Part 1; the history of the Gateway To The Sierras sign The "Clovis Gateway To The Sierras" sign located in Oldtown Clovis along Clovis Avenue between 4th Street and 5th Street. During 1933 Legislative Route Number 76 was extended with a second segment plotted between Huntington Lake and Fresno. The new segment passed through Oldtown Clovis westbound via Tollhouse R

Thank you for the information about the history of US Route 89 in Arizona. I am aware of some of the history but not in the detail you provided. I have been working on a project to promote travel on US 89 for about 15 years. I wrote an article on what I learned about the history of 89 between Canada and Mexico for my website. Have you researched any of the other sections of the highway? The website is usroute89.com

We do have quite a bit on US 89 in Arizona. Off the top of my head some of the articles on US 89 that we have feature; the Navajo Bridge/US 89A, the 1911 Cameron Suspension Bridge, former US 66/89 in Williams, former US 89 on AZ 89, and former US 89A on AZ 89A.
