SR 20 - Winthrop Vicinity Paving


April 2017

Work will begin as soon as weather conditions allow.

Contract #8999 was awarded on January 18, 2017 to Central Washington Asphalt, Inc. for $1,258,802,30, two percent over the engineering estimate.
Design modifications suggested by attendees at last August's open house were included in the final design for the project. 

This P-1 Preservation program project repaves 1.86 miles of SR 20 from MP 192.46 to MP 194.32 through the town of Winthrop in Okanogan County. In addition to the pavement preservation, collision prevention work has been added to increase safety and improve pedestrian travel by adding sidewalk curb ramps to comply with current ADA standards.

Why is WSDOT paving SR 20 through Winthrop?
This project will prevent further deterioration to the existing roadway, maintaining it at the least possible life cycle cost and increasing safety and improving pedestrian travel by updating sidewalk curb ramps to comply with current ADA standards.
