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 in April 2019 and was completed in June 2022.
