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.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l...

Massena Center Suspension Bridge

The Massena Center Bridge, also known as the Holton D. Robinson Bridge, has had quite the tumultuous history. Situated on the Grasse River just east of Massena, New York in the hamlet of Massena Center, the Massena Center Bridge is a reminder of the efforts the community has made in order to connect over the river. The first and only other known bridge to be built at Massena Center was built in 1832, but that bridge was never long for this world. During the spring of 1833, the Grasse River dammed itself due to an ice dam, flooded and lifted the bridge off its foundation, destroying the bridge in the process. The floods were frequent in the river during the spring, often backing up the river from Hogansburg and past Massena Center, but not to nearby Massena. After the first bridge disappeared, local residents had to resort to traveling seven miles west to Massena to cross the next closest bridge, and that was no easy task for a horse and buggy. However, it was many decades befo...

The Dead Man's Curve of Interstate 90 and Innerbelt Freeway in Cleveland

"Dead Man's Curve" refers to the transition ramp Interstate 90 takes between Cleveland Memorial Shoreway onto the Innerbelt Freeway in downtown Cleveland, Ohio. Said curve includes a sharp transition between the two freeways which is known for a high rate of accidents. Currently the curve (not officially named) has a 35 MPH advisory speed and numerous safety features intended to mitigate crashes. When the Interstate System was first conceived during 1956, Interstate 90 was intended to use the entirety Cleveland Memorial Shoreway and connect to the Northwest Freeway through Lakewood. The Innerbelt Freeway was initially planned as the northernmost segment of Interstate 71. The extension of Cleveland Memorial Shoreway west of Edgewater Park was never constructed which led to Interstate 90 being routed through the Innerbelt Freeway.

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.
