Wyoming Highway 22 (WYO 22) is a 17.53-mile-long (28.21 km) state highway in the U.S. State of Wyoming known as the Teton Pass Highway in Teton County Wyoming. WYO 22 spans 17.53 miles (28.21 km) from Idaho State Highway 33 at the Idaho-Wyoming state line to the concurrency of U.S. Routes 26, 89, 189, and 191 in Jackson.

Route description

After the Idaho-Wyoming state line, WYO 22 becomes Teton Pass,^{[citation needed]} later passing through the community of Wilson, a census-designated place (CDP) west of Jackson. On the eastern border of Wilson, at 13.51 miles (21.74 km), WYO 22 intersects the southern terminus of Wyoming Highway 390 (Moose-Wilson Road) before crossing the Snake River.^[1] WYO 22 then continues east to Jackson where it ends at U.S. Highway 26/89/189/191 (Broadway).^{[citation needed]}

History

WYO 22 used to connect to former Alternate US 20, which began at U.S. Highway 20 in Sugar City, Idaho, following Idaho State Highway 33 until the state line, then connected with WYO 22. Alternate US 20 used to end at the state line, where it was redesignated as WYO 22, as Wyoming did not extend the route into the state. If that route had been extended, it would have taken over the entire route of WYO 22, to then overlap U.S. Highway 26 until it reached U.S. Highway 20 in Shoshoni.^{[citation needed]}

Major intersections

The entire route is in Teton County. ^[2]
