(Sept. 30, 2020) Starting Monday, Oct. 5, a new phase of construction begins on SW Naito Parkway as the Portland Bureau of Transportation (PBOT) continues work on the SW Naito Parkway Improvement Project, funded by Fixing Our Streets. 

Portlanders can expect delays when traveling on SW Naito Parkway. Beginning the week of Oct. 5, people driving can expect both southbound lanes of SW Naito to be closed from Harrison to Madison streets. Two-way access on SW Naito Parkway will be maintained by temporarily converting one of the two northbound lanes to a southbound lane. Intersections will remain open at SW Columbia, Clay, Market, and Harrison streets. These changes will allow crews to safely perform necessary demolition, trenching, and construction along the westside of Naito Parkway. This phase is expected to last through early 2021.

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. PBOT greatly appreciates the patience and understanding of nearby residents and businesses.

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

The 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 Street, and a full pedestrian signal at SW Jefferson with connections to Tom McCall Waterfront Park. In partnership with Multnomah County, PBOT will also be installing a new traffic signal on the Hawthorne Bridge onramp to improve traffic operations for vehicles approaching from SW Naito Parkway.

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