Ames crews from the Rocky Mountain and Western Regions are working double shifts seven days a week on the Teton Pass Big Fill project.
The goal: Get as much done as possible before snow starts to fall.
A portion of Wyoming Highway 22/Teton Pass collapsed in a landslide the weekend of June 8. The pass is a critical route for people who live in Idaho and commute to Jackson, Wyoming, for work. Drivers are using a temporary bypass while Ames constructs a permanent solution.
Divided into two work packages, the Big Fill is the first alternative delivery project for WYDOT. Work package 1, completed on Sept. 28, involved 66,822 cubic yards of excavation and the installation of 61,700 square feet of soil nail walls.
The elevation of the roadway on the jobsite is 7,600-7,710 feet. The team is working to get the fill placed back to an elevation of 7,166 feet before winter conditions shut down the project, says Project Manager Rob Wise.
The area sees up to 400 inches of snow in a season. The project also involves working with the National Forest Service and contending with the presence of grizzlies, black bear, and deer.
After the winter shutdown, work will resume in April 2025 and be completed by July.
