The project stabilizes 4 slopes west of the summit. One is between MP 64.1 and MP 63.9, two, MP 63.2 to MP 63, three, MP 63 to MP 62.6, and the fourth is from MP 61.25 to MP 60.90.

This ditch below the "Old Faithful" avalanche zone will be enlarged. (MP 63 to MP 62.6).
Season 2 construction began May 13 and was shut down for winter on Nov. 1, 2013. Work will resume next summer.

Season 1 construction began May 9, 2012 and continued until winter shutdown on November 1.
The entire project is scheduled for 230 working days which translates to three construction seasons due to the later start and early end to the work as a result of the weather at 4,000 feet of elevation in the Cascades.
Significant traffic impacts are not anticipated as the highway is four lanes wide through the entire section and even with two of them closed, two way traffic (one in each direction) will be be maintained. Space for bikes is included.Sign up to receive US 2 Stevens Pass to Wenatchee email updates
This P3 Unstable Slopes Preservation Program project stabilizes four different rock slopes along US 2, in a three mile section from the Stevens Pass Summit, west.
Why is WSDOT
stabilizing these slopes?
This project is to reduce the potential for loose rocks to roll down onto the roadway, creating driving hazards.
Stabilization techniques recommended by WSDOT Geotechnical branch and our contract-consultants, Golder Associates, includes tree and debris removal, scaling of loose rocks from the slopes, installing rock bolts, installing steel cable netting and blasting of the lower slope to enlarge the containment ditch next to the highway.
The End Result
This project is designed to reduce the potential for rockfall hazards on the roadway.
- Increasing the stability of these rock slopes is being done to reduce the potential for rockfall onto US 2.
- Increasing snow storage and debris retention in widened ditches should reduce maintenance costs.
- The widened ditches may also reduce winter travel delays due to snowslides that don't reach the roadway.
What is the project timeline?
Construction started May 9, 2012. The work is scheduled for 230 working days, extending over 3 construction seasons (2012,13, & 14).
