Why is WSDOT
pave State Route 28?
A Hot Mix Asphalt overlay was necessary to preserve the load carrying ability of the pavement structure. WSDOT worked with the Chelan County PUD to channelize the Rock Island Grade Road intersection at Rock Island Dam.
The End Result
This project restored the structural integrity of the pavement and improves drainage, reducing future maintenance. It also improves safety with more visible striping. A channelized intersection, funded by the Chelan County PUD, includes additional drainage features and illumination.
Project BenefitsExtends roadway life.
