This Phase 1 of the East-West Corridor project was permitted under a separate SEPA document. This phase focuses on building a roundabout with four connections to the north-south and east-west sections of Butterfield Road. The eastern terminus of the project will be at the intersection of Keys Rd and Butterfield Road. Also, this phase will be relocating and/or building water, sewer, cable and power connections throughout the corridor starting at the Roza Canal working east along the roundabout and east-west section of Butterfield Road. Phase 1 of the project will continue to increase the East-West Corridor's opportunities for new public transit routes, improved emergency response times, and non-vehicular transportation.
