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.
