C-TRAN officially broke ground on the Mill Plain BRT project in September 2021. Construction areas will include a new transit center near 184th Avenue and Mill Plain, and 37 new station platforms along the 10-mile Mill Plain corridor.

Construction will occur in phases during the two-year work period, meaning different areas will see construction activity at different times.

Current activity: Fall 2021

• Construction at the site of the new Mill Plain Transit Center, near 184th Avenue and Mill Plain Boulevard
• No significant traffic impacts expected
