(May 28, 2021) The eastbound Hawthorne Bridge bridge ramp from northbound Naito Parkway will remain closed as crews for the Portland Bureau of Transportation’s (PBOT) SW Naito Parkway Improvement Project complete improvements and install new traffic signal equipment on the bridge.

In partnership with Multnomah County, PBOT is installing a new traffic signal on the northbound SW Naito Parkway to eastbound Hawthorne Bridge onramp. The new signal will make it easier for vehicles to get on the bridge from SW Naito Parkway. It will also make crossing the ramp safer and more predictable for pedestrians and people on bikes.

Through June 14, the eastbound Hawthorne Bridge ramp from northbound Naito Parkway is CLOSED to all users. Follow the detour signs to SW Clay or Jefferson streets, take a right on SW 2nd Avenue, and right on SW Madison Street to travel eastbound across the Hawthorne Bridge. People biking and pedestrians should also follow the detour signs to the bridge sidewalks and will be directed to use a temporary connection on the south bridge deck

During this time, there will also be single lane closures as needed outside of peak hours on the Hawthorne Bridge. Construction on the SW Naito Parkway Improvement Project is expected to be complete this fall.

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 weather dependent and subject to change.

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.

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 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 streets. A second project on SW Naito Parkway, Better Naito Forever, is also continuing construction and is expected to be complete by the end of 2021. Learn more about Better Naito Forever online.

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. Watch a video fly-through of the final project design.

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.
