Engineering And Design
PBOT plans to change NE Alameda Street from NE Sandy Boulevard to NE 56th Avenue to one-way westbound-only for auto traffic. The change will remove the NE Alameda St signal phase from the complex 5-leg intersection at NE Sandy Blvd, giving more “green time” to NE Sandy Blvd and NE 57th Ave.
Installation in 2022

What's happening now?
UPDATED: PBOT Maintenance Operations staff completed work on NE Alameda between 56th and 57th in mid-Saturday, 2022.
Site observations by staff are taking place weekly.
About the project
- PBOT will improve traffic circulation and signal timing at a complex intersection. It will remove the NE Alameda St signal phase from the 5-leg interchange.
- It will give more “green time” to NE Sandy and NE 57th avenues, reducing delay to TriMet bus lines 12 and 71.
- It will improve traffic operations on NE Sandy and NE 57th Ave.
- It will reduce cut-through traffic on the NE Alameda Neighborhood Greenway.
- No changes will be made to the bicycle and pedestrian signal phase at NE Alameda.
What will the pilot look like?
- Low cost, non-permanent materials to allow for adjustments.
- Before and after vehicle volume collection to monitor traffic changes on other streets.
Traffic Impact and Analysis
PBOT collected data at 8 locations during the fall and winter of 2021 and 2022 to understand how neighborhood traffic is operating (see map and information, below). Approximately six to twelve months after implementation, another round of data collection will take place using the data collected previously as the baseline. The last 10 years of traffic data collected by PBOT can be found on our publicly available webmap
What else do we know?
- We know slow and unreliable transit perpetuates inequities and disproportionately burdens low-income households and communities of color, and impedes access to jobs, school, health care, services and daily needs.
- We know residents are concerned about vehicle volume impacts on other neighborhood streets in the project area. Roughly six months after the pilot project installation, PBOT will collect vehicle data in the area, and impact mitigation strategies may be developed as needed.
