Wyoming Highway 22
Wyoming Highway 22, also known as the Teton Pass Highway, is a state highway in Teton County, Wyoming, United States. It connects Idaho State Highway 33 at the Idaho-Wyoming state line with U.S. Routes 26 / U.S. Route 89 / U.S. Route 189 / U.S. Route 191 in Jackson.
Route description
WYO 22 begins at the west end of SH-33 on the Idaho-Wyoming state line in the Caribou–Targhee National Forest. From its western terminus, WYO 22 proceeds southeast for along the north bank of Trail Creek as it climbs over to the Teton Pass, which has an elevation of above sea level. At Teton Pass, WYO 22 leaves the Caribou–Targhee National Forest and enters the Bridger–Teton National Forest.East of the Teton Pass, WYO 22 runs along the border of the census-designated place Wilson as it begins its nearly descent to Jackson on a winding easterly course. Approximately farther east, WYO 22 enters Wilson and then, roughly later, leaves the Bridger–Teton National Forest. About farther east, after crossing Fish Creek, WYO 22 begins running along the border of Wilson and the CDP of Moose Wilson Road.
Shortly thereafter, at about along its route, WYO 22 connects with the southern end of Wyoming Highway 390 at a T intersection. Quickly thereafter, WYO 22 leaves both Wilson and Wilson Moose Road as it crosses the Snake River.
East of the Snake River, WYO 22 continues a winding east-southeasterly course for just under to enter Jackson and promptly reach its eastern terminus at US 26 / US 89 / US 189 / US 191 at a T intersection.
History
WYO 22 used to connect to former Alternate US 20, which began at U.S. Highway 20 in Sugar City, Idaho, following SH-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 US 26 until it reached U.S. Highway 20 in Shoshoni.On June 8, 2024, WYO 22 suffered a “catastrophic” failure when a portion of the road collapsed in a landslide at milepost 12.8, less than by air from the Idaho border. A detour, constructed by a contractor of the Wyoming Department of Transportation, was opened to traffic on June 28, 2024. The detour has a sharper curvature and a grade of 11.2 percent, with a reduced speed limit of, but the former gross vehicle weight restriction remains.
