A Portland Bureau of Transportation flood protection wall assembly exercise will require lane closures on North Marine Drive just east of North Portland Road 8-10:30 a.m. Wednesday, Nov. 12. Marine Drive will be reduced to one lane in each direction during the exercise. Officials may also require some brief, periodic closures of all lanes to allow crews to move cranes or other large equipment across the roadway. Portland city officials conduct flood wall exercises annually. During the event, crews aim to refresh their skills and test equipment that would be needed to protect public safety and property in the event a Columbia River flood. Drivers in the area are 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. Current weather forecasts show rain developing later in the afternoon Wednesday.
