SR 506 - Ryderwood to I-5 - Chip Seal

Project news

During the summers of  2016 and 2017, contractor crews working for the Washington State Department of Transportation will resurface 11 miles of SR 506 from Ryderwood to Interstate 5.

Pavement were completed in 2016 and crews will chip seal the road in the summer of 2017.

Why is WSDOT resurfacing SR 506 in Lewis County?
The asphalt on several portions of SR 506 is nearing the end of its useful life and this work is needed to preserve the road for the next several years. Sections of the highway are showing signs of deterioration such as cracking and rutting. Deferring this work would result in more expensive costly repairs.

The End Result
In addition to providing drivers a smoother ride, this project helps WSDOT preserve the roadway along SR 506 that connects Vader and Ryderwood.
