(Nov. 7, 2025) The Portland Bureau of Transportation (PBOT) advises the traveling public that a flood protection wall assembly exercise will require lane closures on North Marine Drive just east of North Portland Road on Wednesday, Nov. 12 from 8 to 10:30 a.m.
Marine Drive, an important route for freight in North Portland, will be reduced to one lane in each direction during the exercise. It may also require some brief, periodic closures of all lanes to allow crews to move cranes or other large equipment across the roadway.
The public is advised to expect delays, travel cautiously, observe all lane closures and directions by flaggers, and use alternate routes if possible.
Local access to residences and businesses will be provided.
This work is weather-dependent, and the schedule may change.
PBOT is the City of Portland's lead on response to a variety of emergencies, including floods. The floodwall exercise, conducted annually, allows crews to refresh their skills and test equipment that would be needed to protect public safety and property in the event a Columbia River flood.
