Seattle Public Utilities (SPU) installed a new water main along Western Avenue from Yesler Way to Spring Street in the Pioneer Square neighborhood in 2016. After replacing the water main, the roadway was temporarily restored. The new, 24-inch steel water main is able to absorb additional ground settlement and withstand seismic activity.
What's happening now?
