In August 2020, we finished work with our geotechnical probe, or geoprobe.
Based on information gathered from the geoprobe, we learned that we needed to explore alternate drilling technologies and alignments. To support that effort, the contractor performed additional geotechnical drilling and sampling in the Willamette River and nearby on the east and west sides of the river in early 2021. The team analyzed that information and is developing a proposal for the best tunneling technology and route to cross the Willamette River.

Work at 1720 SW Naito Parkway
You may see workers in and near the parking lot at 1720 SW Naito Parkway. We’re temporarily sharing this site with the Bureau of Transportation while they work on the SW Naito Parkway Improvement Project, I-405 to Jefferson.
Parking lot and stairway closure
The parking lot and stairway at Southwest Naito Parkway between Southwest Harrison Street and Southwest Market Street are closed to the public for the duration of the project. Use the ADA-accessible ramp on the south end of the parking lot as a detour.
East-side Connection Update
In 2022 we expect to work along Southeast 7th Avenue and along Southeast Harrison Street between Southeast 7th and 11th Avenues to connect the new underground pipe to the existing water system. As this will affect traffic, parking, and driveway access in the area, we’re working with local businesses and residents now to plan for their access needs.
