U.S. Route 89 (US 89) is a part of the U.S. Highway System that travels Flagstaff, Arizona, north to the Canadian border; broken into two segments by Yellowstone National Park where unnumbered park roads serve as a connector. In the state of Idaho, it extends approximately 44 miles (71 km) from the Utah state line near Glencoe to the Wyoming state line near Geneva.

Route description

US 89 enters Bear Lake County from Utah along the western shore of Bear Lake, passing through Glencoe, Fish Haven, and St. Charles. North of the lake, it continues through Bloomington, Paris (the county seat for Bear Lake County), and Ovid before reaching Montpelier, the largest community along the route.[2] US 89 shares a short concurrency with US 30 in Montpelier before it continues eastward over the Preuss Range, a subrange of the Peale Mountains.[3] It crosses the Geneva Summit and passes through Geneva before crossing into Wyoming.[2]

Major intersections

The entire route is in Bear Lake County.
