The Wyoming Transportation Commission awarded a $880,600 emergency bid to Avail Valley Construction LLC during a special meeting on Thursday afternoon, June 13. During the Zoom meeting, Avail Valley shared its plan for the repair work at Teton Pass, which suffered a catastrophic failure on Saturday, June 8, causing almost an entire section of the road near milepost 12.8 to slide into the ravine below. Teton Pass Road, also known as Wyoming Highway 22, links Wyoming and Idaho, and is the main access road from the south to Jackson Hole.
Trouble first emerged on Thursday, June 6, when a large crack stretching across both lanes of the highway was spotted. This prompted a temporary closure and emergency patching by the Wyoming Department of Transportation (WYDOT). However, the situation rapidly deteriorated on Friday, June 7, when a mudslide covered the road, forcing another closure. As crews worked overnight to construct a detour around the damaged section, the landslide continued to move, ultimately causing the catastrophic failure and collapse of the roadway. Thankfully, no employees, contractors or other members of the public were injured in the collapse. No equipment or buildings were lost or destroyed in the collapse either.
Teton Pass also experienced a mudslide at milepost 15.5, which is not related to the 12.8 milepost slide, referred to by WYDOT as the “Big Fill” slide. The slide was discovered June 7.
Avail Valley is based out of Victor, Idaho, and is licensed in Wyoming and Idaho. The company specializes in all types of construction, including commercial, residential, and municipal projects. Avail Valley will construct a box culvert at the slide area at mile marker 15.5. The culvert will help improve drainage in the area. Crews with Avail Valley are aiming to have the project complete so the highway will be ready to reopen once the detour is complete at the Big Fill landslide located at mile marker 12.8 on Teton Pass.
The progress photos from the last two days are incredible as crews are working hard to get this vital road access back open for the summer holidays. Teton Pass sees an Annual Average Daily Traffic (AADT) of almost 10,000 vehicles per day in certain locations along the pass. Summer highs can reach 15,000 vehicles.
Please note, Yellowstone National Park and Grand Teton National Park remain open for visitors during this time.
