SR 506 - Ryderwood to I-5 - Chip Seal - Complete September 2017

Project news

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

In 2016, pavement preservation work was completed. Crews returned in summer 2017 to chip seal the roadway, ensuring it will last for many more years.

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

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