Long Time For Snake River Canyon to Reopen

Highway workers temporarily stopped clearing a massive landslide on highway 26/89 and said it could be a “long time” before the Snake River Canyon is open again for motorists. Northbound traffic on US-26-89 can continue on US 26 into Idaho north of Alpine Junction. That route passes through Irwin and Swan Valley before becoming Idaho Highway 31, which turns to the east through Victor and into Wyoming, where WYO 22 crosses Teton Pass into Jackson. railers will be prohibited on Teton Pass from 6 a.m. to 9 a.m. and from 3 p.m. to 6 p.m. to facilitate daily commuters during the closure. This includes vehicles pulling campers, boats or other types of trailers. A weight restriction of 80,000 pounds also is in effect during those hours. WYDOT geologists are continuing to assess the landslide.
WYDOT is assessing the magnitude of the active slide and the logistics of removing the debris. The slide is estimated to be about 30 to 40 feet high above the road and extends about a quarter of a mile up the hill. The slide consists of large rocks, vegetation and mud which is mixing with water that is running downhill.
