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

Project news

In 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 daytime, single-lane closures for the duration of the project and full 45 minute intermittent closures for a 2-week period while the rock scaling work occurs.

Intermittent single-lane closures will be scheduled for most weekdays, with the exception of between 2:30 to 5 p.m., daily, to allow commuters through the area. During rock scaling work, both directions of SR 14 will be closed for up to 45 minutes at a time, beginning at the top of each hour, and ending at approximately 45 minutes after the hour. Both lanes must reopen once an hour to provide a minimum of 15 minutes to clear traffic. Work will occur during daylight hours.

We understand the 45-minute closures will greatly affect travelers through the area. For the safety of the traveling public, these closures will only occur when crews are performing rock-scaling work. Additionally, these extended closures are scheduled to occur during summer break to avoid affecting the school district and busing routes.
