SR 522 Stage 3
About the Project
This project is a continuation of the SR 522 Stage 1 and Stage 2 improvements. It provides road improvements, including Business Access and Transit (BAT) lanes from the end of Stage 1 and 2 improvements to 83rd Place NE (the new western City limits). Stage 3 of the project is part of the Sound Transit SR 522/NE 145th Bus Rapid Transit (BRT) project that will widen the existing lanes of SR 522 and create BAT lanes in both directions.
Additionally, this project adds a sidewalk on the north side, installs center medians and street lights, and relocates utilities underground.
Construction started on Monday, Apr. 29, 2019 and is expected to be completed in Spring 2022.
The contractor has completed road striping. BAT lanes will be opened in both directions of SR 522 between 96th Ave NE and 83rd Pl NE by Thursday, 5/26.

Transit speed and reliability would be improved with the installation of BAT lanes where none exists. 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.
The Sound Transit 3 ballot measure allocated funding for this project. 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.
The design and right-of-way (ROW) phases of this project were completed in 2018. On March 19th, 2019, the City Council awarded a construction contract to Thomco Construction, Inc., the lowest responsive and responsible bidder.
