SR 14 - 0.8 to 1.1 Miles West of Wind River Rd - Slope Stabilization

Project news

  • This project was awarded to Geostabilization International, LLC on July 21, 2020. 

In late summer 2020, contractor crews working for the Washington State Department of Transportation will begin working to improve the slope stability along two rock slopes, along State Route 14, near Wind River Road, in Skamania County. 

Crews will perform debris and tree removal, rock scaling and they will install rock dowels within the sides of the slope to secure the rock face in place. Once the rock dowels are installed, crews will add a layer of shotcrete against the slope surface to fill cracks and fissures and prevent loose material from falling. Shotcrete is a concrete material that's used to secure the rock face in place and adds an extra layer of stability.  

Needs & benefits

In December 2013, a large rock fall event from this area was recorded, when a large rock approximately 3 feet in size, failed and fell from the slope, striking the jersey barrier below and broke into several pieces covering both lanes of the highway. Several smaller rock falls have occurred on these slopes since the event in 2013. 

This work will be performed to limit these type of rock fall events from happening: improving the safety of the traveling public, reducing costly maintenance repairs and the potential for emergency road closures.

What can travelers expect

Once construction begins, travelers should expect weekday, daytime, alternating single-lane closures for the duration of the project with delays of up to 20 minutes. During rock scaling work, crews will close both directions of SR 14 for 45 minutes at the top of each hour. Both lanes of the highway must reopen once an hour to provide a minimum of 15 minutes to clear traffic. Rock scaling work will occur weekdays, during daylight hours.

We understand the 45-minute closures will greatly impact travelers through the area, however, for the safety of the traveling public, these closures will only occur when crews are performing rock-scaling work. Be sure to sign up for notifications so you can plan your trips ahead.
