Overview
In January 2006, WSDOT's chief engineering geologist delivered an unstable slope report to Governor Gregoire which evaluated the slope hazards along the I-90 corridor near Snoqualmie Pass.
These two slopes were identified in the report as high hazard / high risk slopes. They are located approximately 2 miles west of the summit on the north side of the westbound lanes. The two slopes are adjacent to the area where a rock slide caused three fatalities on September 11, 2005 and shutdown westbound I-90 for more than 13 hours.
 | Improves Safety
By stabilizing the existing slopes, WSDOT will reduce the potential for future rockslides.
|
 | Relieves Congestion
This project will reduce the possibility of emergency closures and traffic delays due to rock slides.
