About three weeks after a landslide prompted officials to close a major highway near Grand Teton National Park, a detour has been opened to public traffic, the Wyoming Department of Transportation said.

In early June, a crack opened on Wyoming Highway 22 in Teton Pass, and officials closed the road for patching. It reopened to traffic, but two days later, the road collapsed.

A two-lane, paved detour was opened Friday, with only vehicles weighing less than 60,000 pounds allowed to use the road.

“(The department’s) professional geologists evaluated the stability of the detour roadway. Geotechnical analysis confirms that the temporary detour meets or exceeds the minimum requirements set forth in Federal Highway Administration guidelines,” the transportation department said in a news release.

According to the U.S. Department of Transportation, the Teton Pass corridor “serves as a critical commuting route and facilitates the transportation of goods and services that are the foundation of Wyoming and Idaho’s growing regional economies.”

According to a graphic posted on the Teton County Department of Transportation office’s Facebook page, a detour has been constructed right next to the section of Highway 22 that collapsed.

The new road is about 600 feet long and has a sharper curve than the section of highway that collapsed. New drainage has been added.

Engineers and others are redesigning the original section of highway, and the Department of Transportation’s goal is to rebuild the road before winter.
