FAQs

Construction starts in late 2021, and overall will take four years, but most locations will see much shorter work durations. There will be times when construction is occurring in several locations simultaneously.

King County is committed to being a good neighbor during construction. Staff will provide advance notification of construction activities as well as a 24-hour construction hotline. This is a big project and most people won’t be impacted by all of it. That’s why King County is planning targeted communications for different locations and different concerns.
