We will build a new bridge on the north side of the existing Snohomish River Bridge. The new bridge will carry westbound SR 522 traffic. The new bridge will be 1700 feet long and will be nine feet higher than the existing bridge.
At the northern end of the project, we will build a new roundabout at SR 522 and 164th Street SE, on the west side of SR 522. We will also realign the on- and off-ramps to westbound SR 522.
