What’s happening now?
The project has been completed.
Project Background and Description:
Currently, the T-intersection at NE 122nd Avenue and Marine Drive has a stop sign with a flashing red light for traffic turning onto Marine Drive. Traffic on NE Marine Drive does not have to stop, often causing long backups during peak travel hours for people wanting to turn from 122nd.
The new signal will help drivers on 122nd Avenue to turn onto Marine Drive. It will also include a protected left turn for people turning from westbound Marine Drive onto southbound 122nd Avenue. Additional features include a bike signal to help people on bikes cross Marine Drive from the southeast corner of the intersection, allowing them to connect to the westbound bike lane on Marine Drive. The traffic signal is located on a flood control levee for the Columbia River, so PBOT coordinated with Multnomah County Drainage District and obtained permits from U.S. Army Corps of Engineers.
PBOT will also be installing shoulder and centerline rumble strips from NE 33rd to 185th Avenues. On Marine Drive, 19% of crashes are lane-departure crashes where a person drives out of their travel lane. On average, centerline rumble strips reduce all crash types by 9% and head-on or sideswipe crashes (which are often serious) by 44%. On average, shoulder rumble strips reduce crashes by 36%.
