Mileage: in 1989 AASHTO listed a figure of 1837 miles for US 89... however, that included the mileage of US 89's associated alternate routes. According to the state subtotals on AASHTO's 1989 spreadsheet, mainline US 89's actual end-to-end total was 1661 miles... but at the time, US 89 still ended in Nogales. Since then it has been truncated to Flagstaff, and our own 2020 measurement yielded 1239.0 miles (with an additional 94.8 implied miles through Yellowstone National Park, bringing the end-to-end total to 1333.8 miles).

Possibly that was westbound US 50 (which continued to the right with US 91) and northbound US 89 (which ended there).
In 1934 the north end of US 89 was extended to its present terminus on the Canada border in Montana, at a port of entry called Piegan. All during that time, the south end of US 89 was at the Mexico border in Nogales AZ: |
Here is a nice (but unfortunately copyrighted) photo showing the south end of US 89 in 1955. In 1992 US 89 was decommissioned through much of Arizona; since then the south end has been at Flagstaff. Technically -- since US routes are not signed through Yellowstone National Park -- US 89 consists of two separate segments. Photos from its interruption points are available on the pages for North Yellowstone and South Yellowstone.
