This project is a continuation of the SR 522 Stage 1 and Stage 2 improvements. It will provide road improvements and business access and transit (BAT) lanes from the end of Stage 1 and 2 improvements to 83rd Place NE (the new western City limits). The City has federal funding for Design and Right-of-Way Acquisition.
The Sound Transit 3 ballot measure allocated funding for this project. The City is continuing to meet with Sound Transit staff to review the project schedule. Currently, the project is scheduled to begin construction in early 2019 and last for approximately two years.
The City held a Public Hearing regarding an appeal of the State Environmental Policy Act (SEPA) threshold determination for this project on August 18, 2016. Read the notice.

Transit speed and reliability would be improved with the installation of BAT lanes where none currently exist. This would support the vision of downtown Bothell as a transit-friendly urban core. Installation of a sidewalk on the north side of the highway would allow the neighborhoods to access intersections along SR 522 and cross the regional trail system. This would promote pedestrian and bicycle usage.
