PBOT wants to make Portland’s Northwest District safer and more convenient for walking, biking, and taking public transit. To do it right, we need your feedback! Please review this project concept and tell us what you think.
Project Description
Full pavement reconstruction from Lovejoy to Vaughn (including concrete bus pads), curb extensions with marked crosswalks at Marshall, Overton, Quimby, Pettygrove, and Savier, and a signal rebuild at Thurman. Address sidewalk accessibility issue at Raleigh signal. Adjust location of Thurman/23rd bus shelter to move it out of the pedestrian through zone. Upgrade signal and add protected left turns from 23rd to Thurman to address transit delay and improve safety.
Project Goal(s)
- Improve the pedestrian realm by upgrading and providing new curb extensions thoughout the corridor.
Key Consideration(s)
- Some on-street parking spaces might be impacted to provide space for new crossing improvements.

Protected Left Turn Signal Phase
Map
At “T” intersections, there is an opportunity to provide longer curb extensions with more greenery along the length of the intersection. This prioritizes pedestrians, provides a nicer place to be, and lowers traffic speeds by narrowing the roadway temporarily. 23rd & Marshall is one example in NW Portland where this kind of design treatment could be deployed.
By adding a protected signal phase, vehicles turning left are given a dedicated time to make the otherwise difficult left turn. The signal phase would be coordinated with the pedestrian walk signal to eliminate ‘permissive’ left turns and reduce/eliminate conflicts between people walking and people driving.
