Why is King County doing this project?

This road segment ranks high on the King County’s ITS strategic plan due to traffic volumes and high accident locations. The project completes the Avondale corridor ITS project and gives King County and the City of Redmond the ability to control and monitor traffic flow along Avondale Road between Woodinville Duvall Road and SR 520.
