North Creek Interceptor construction began Monday, breaking ground on phase one of the three phase project that will close portions of streets between 6 a.m.and 5 p.m. on weekdays until mid-August

King County’s contractor is restoring and paving portions of 20th Ave. Southeast, 222nd Street Southeast and 23rd Dr. Southeast, all south of 220th Street Southeast.

The project aims to repair and replace a 2-mile pipeline that has been serving the Bothell area since 1970. The new pipeline will increase system reliability and accommodate population growth in this portion of the service area.

This work will be completed in three phases this summer and early fall to help maintain access to businesses. The county will provide email updates on phase two and phase three as workers move north along 20th Ave. Southeast.

This phase of the project closes 23rd Dr. Southeast between 222nd St. Southeast and to 223rd Street Southeast, and 222nd Street Southeast between 23rd Dr. Southeast and 20th Ave. Southeast.

The construction will detour traffic to the south around the work area along 20th Ave. Southeast, 224th St. Southeast, 23rd Place Southeast, and 223rd St. Southeast. Along 23rd Dr. Southeast going south, there will be no through traffic past the intersection at 222nd Street Southeast, or through to 223rd St. Southeast. Motorists here will be detoured north to 220th St. Southeast.
