In November and December, Portland Water Bureau crews will start digging to allow for an exploratory drill to be placed in a parking lot at 1720 S.W. Naito Parkway between Harrison and Market streets related to the Willamette River Crossing project. Between 2020 and 2022, the bureau will be installing an earthquake-resilient water pipe deep under the Willamette River.
Beginning in late October and continuing through 2020, this work will have occasional traffic impacts on those traveling along Southwest Naito Parkway and Harbor Drive. Please prepare for the following changes to traffic. Businesses along Naito Parkway will remain open during construction.
The traveling public is reminded to stay alert and use caution as traffic may suddenly slow or stop. Please allow extra time when traveling through the area. Follow all signs and flagger directions to ensure everyone's safety. To avoid traffic delays, motorists are encouraged to use alternate routes around the worksite.
Portland’s water mains (pipes) that cross the Willamette River are more than 50 years old and will probably not survive a major earthquake. As part of the Portland Water Bureau’s commitment to preparedness, we are installing an earthquake-resilient water pipe deep under the Willamette River. This new water pipe will help ensure that we can deliver safe and abundant water to the west side, even after an earthquake.
This project is currently in the design and exploration phase. This phase includes locating underground utilities and conducting a geotechnical probe, which will provide important information about soil deep underground and help us confirm the best path across the river.
