Redmond Ridge Drive NE Roundabout

Project No.:  1134081
Project limits:  Intersection of Redmond Ridge Dr. NE at NE Alder Crest Dr.
Project type:  Capacity
Thomas Bros. Map No.:  538B1

Project description

To design and construct a roundabout on Redmond Ridge Drive NE at NE Alder Crest Drive including curb, gutter and sidewalk.

Why is King County doing this project?

Redmond Ridge Drive NE is a major arterial and runs north to south. It is located east of the City of Redmond, and intersects with NE Novelty Hill Road, which is also a major arterial. This project will support the anticipated build-out of the Redmond Ridge Business Park and its associated economic benefits. Once the business park is developed to its projected capacity, vehicle delay at the intersection will significantly increase. The roundabout is intended to improve intersection level of service, and neighborhood pedestrian safety for area residents, including children traveling to the nearby park and a planned middle school.
