(August 26, 2021) As work progresses on the Portland Bureau of Transportation’s (PBOT) SW Naito Parkway Improvement Project, street paving has been scheduled for Monday, Aug. 30 and Tuesday, Aug. 31 from 8 p.m. to 6 a.m. This paving work will require a full closure of Naito Parkway between SW Jefferson and SW Harrison streets. It has been scheduled to occur in the evening to minimize impacts to the traveling public. 

All traffic on SW Naito Parkway between SW Harrison and SW Jefferson streets will be detoured between 8 p.m. and 6 a.m. on Monday and Tuesday night. Northbound traffic will be detoured to SW 4th, SW Columbia, and SW 2nd avenues. Southbound traffic will be detoured to SW 1st Avenue. Flaggers will be present during the closure to allow access to local businesses. We ask the public to travel cautiously, observe all lane detours and directions by temporary traffic signals and flaggers, and use alternate routes if possible. This work is weather dependent and subject to change.

Construction on the SW Naito Parkway Improvement Project is scheduled to be substantially complete this fall. PBOT estimates that SW Naito Parkway, from SW Market to SW Jefferson streets, will be able to be fully reopened by the end of October. Due to the unanticipated need to replace an asbestos-coated water line between SW Harrison and SW Market streets, this portion of final paving is being delayed until the water line is replaced. Crews will return in the spring for final paving of this section of SW Naito Parkway.

This work is part of a major transformation underway on SW Naito Parkway, with significant improvements stretching from I-405 to SW Jefferson Street and the Hawthorne Bridge onramp. From I-405 to SW Harrison Street, the street is being repaired and repaved. Beginning at SW Harrison and extending north to SW Jefferson, SW Naito has been completely rebuilt from the road base on up. Additionally, the project is constructing a two-way separated off-street path between SW Harrison and SW Clay streets.

PBOT greatly appreciates the patience and understanding of nearby residents and businesses. Learn what you can expect in our work zones and how you can help everyone stay safe by watching this video: https://youtu.be/lx3RkJjkjSE

The SW Naito Parkway Improvement Project also includes safety and efficiency improvements for all travel modes, with significant upgrades to the signal infrastructure along this stretch of SW Naito Parkway to improve the safety and efficiency for pedestrians and people driving and biking. Among the improvements are traffic signal upgrades and SW Market and Clay streets, a new pedestrian signal midblock between SW Harrison and SW Clay streets, and a full pedestrian signal at SW Jefferson with connections to Tom McCall Waterfront Park.

As the project progresses, it will require future detours. Learn more and sign up to receive the latest construction updates on the SW Naito Parkway Improvement Project - I-405 to SW Jefferson website.

The SW Naito Parkway Improvement Project is funded with $1,600,000 from Fixing Our Streets, with additional funding from Transportation System Development Charges and other sources. Fixing Our Streets funds are also leveraging additional Oregon Department of Transportation funding.

A second project on SW Naito Parkway, Better Naito Forever, is also continuing construction. Work on PBOT's related Better Naito Forever project to the north continues as well, with concrete pours for the new sidewalk and median islands beginning next week. Better Naito Forever is scheduled to be complete this winter.
