US highway endpoint at Port of Piegan, MT
At the time, the US 89 designation went only as far north as Spanish Fork UT. But then in 1934 US 89 was extended northward along its current path: through the rest of Utah, plus Wyoming and Montana (via an implied route through Yellowstone). It met US 87 at Armington MT (southeast of Great Falls), and replaced that route up to its present terminus on the Canada border, at a port of entry called Piegan. US 87 ended at Armington for a few years, but then was extended through Great Falls and up to Havre in the 1940s. This first photo is looking northward at Piegan:

The mountains in the distance are in Glacier National Park; the mileage sign makes reference to Babb, Browning, and Great Falls.
