Status

April 2014

  • Traffic is diverted onto a 1,000-foot stretch of temporary roadway along SR 20 three miles east of Rockport. Drivers should watch for minor changes to the roadway's route, a reduced speed limit (50 to 35 mph) and warning signs.
  • In early December, crews began building the temporary roadway section to keep drivers moving while we work along the river.
  • Watch for crews and turning trucks in the area, but this work should not cause major delays.
  • Crews relocated utilities and removed a few trees along SR 20 from milepost 101 to 104 (just east of Rockport) fall 2013.
  • The project should be completed by fall 2014.
  • Check out our project folio for more project information (pdf 840 kb).

Why is WSDOT installing engineered logjams in the Skagit River?
There’s a stretch of SR 20 three miles east of Rockport in Skagit County that’s constantly buffeted by the Skagit River, especially during flooding. When the river is running high, it eats at the riverbank and, at times, has threatened to even wash out the road. On several occasions in recent years, we’ve had to line the riverbank with large rocks to protect the highway from the barrage of water. These temporary and costly emergency-repair projects only put a Band-Aid on a bigger problem, and they negatively impacted fish habitat.

The End Result
In an effort to protect the highway and improve the river habitat over the long-term, we’re going to build engineered logjams along the riverbank. The logjams will help buffer the highway from the eroding forces of the river.

Project Benefits
Not only do these logjams protect the highway, they also improve the conditions in the river for fish. The project is a win for drivers, our maintenance crews, and the environment.
