What is the best time of the year to do a road trip on US Route 89?
If you are planning to drive the entire length of US Route 89, then the best time is from July to September starting at Glacier National Park on the Canadian border. Glacier and Yellowstone are the last parks to fully open in the summer. Ideally allow three or four weeks for the journey in order to fully enjoy everything there is to see although it can be done in two weeks. The later you start the cooler it will be when you get to Arizona. Of course, summer is the busiest time for all the parks and other tourist attractions from the Grand Canyon to Glacier. It is a good idea to make reservations for the park lodges well in advance and the same for campgrounds where available.
Southern Arizona is best visited from October to May unless you like the heat. When conditions are right, spring wildflowers bloom from March to May and cactuses put on their best show in the spring.
Northern Arizona and southern Utah are year ‘round destinations. The Grand Canyon, Zion and Bryce Canyon National Parks are open and accessible all year. You’ll experience moderate temperatures and weather in the spring and fall. Summer can be hot but not unbearably so. You can expect snow in the winter which enhances the beauty of the region. The one exception is the North Rim of the Grand Canyon which is only open in the summer usually from the middle of May to the middle of October depending on snow conditions.
Travel on US Route 89 in Wyoming and Montana is very weather dependent. Most of the facilities in Glacier National Park close in early September and reopen in late May.

What is the history of US Route 89?
Until the middle of the 1920’s, interstate roads in America were created by private booster groups and given names such as the Lincoln Highway, the Old Spanish Trail and the National Old Trails Road. As traffic increased with over ten million cars registered, state highway officials asked the federal government for help in replacing this confusing and unregulated system with a standard method of designating highways. The result was a numbering system for interstate highways announced in 1925.
The plan was simple in concept but required numerous compromises in execution. East-west roads were given even numbers, north-south roads were given odd numbers. Transcontinental east-west routes had numbers ending in zero with U.S. 2 in the north to avoid a U.S. 0. Main north-south routes ended in one starting in the east. Other multi-state routes were fitted within the resulting grid.
In the 1925 plan from the US Department of Agriculture’s Bureau of Public Roads (BPR), US 89 was a minor route connecting Thistle, Utah, and Flagstaff, Arizona. The BPR plan was turned over to the American Association of State Highway Officials (AASHO) for revision and approval. Over the next two years, numerous meeting were held and compromises reached to produce the final U.S. numbered highway system in November of 1927. The total mileage of selected roads was 96,626.
US 89 had grown to 917 miles beginning in Spanish Fork, Utah and ending at the Mexican border at Nogales, Arizona.
In 1934, US 89 became a border to border route when it was extended to the crossing station at Piegan, Montana. The total length was 1685 miles.From 1940 to 1992 an alternate scenic route, US 89A, was designated between Prescott and Flagstaff, Arizona, running through the Verde Valley and Sedona.
Construction of Glen Canyon Dam on the Colorado River in northern Arizona began in 1956. With the completion of a bridge in 1959, US 89 was rerouted from Bitter Springs to Page and across southern Utah to Kanab. The original route which crossed the Colorado at Marble Canyon, was designated as an alternative. It is now officially US 89A crossing the Kaibab Plateau north of the Grand Canyon.
In 1992, the section of US Route 89 from Nogales to Flagstaff, Arizona, was decommissioned as a Federal Highway because Interstate Highways now connect Nogales and Flagstaff.
