In a week or so, you might see something unusual on the Alaskan Way Viaduct that has nothing to do with tunneling: The city announced this afternoon that “a major film production” will shoot in Seattle for six days between May 19th and 26th, including filming that will lead to “rolling slowdowns” on the Viaduct. The announcement explains, “Traffic is never completely stopped, but there will be brief periods where it will be slowed to follow the production as it moves along the Viaduct. Production will take place intermittently outside of peak driving hours, between 9:00 AM and 3:00 PM on May 19, 2016 – May 26, 2016.” Scenes also will be filmed in Pioneer Square. The city’s announcement doesn’t identify the film; Office of Film and Music spokesperson Joe Mirabella says, “The City’s longstanding policy is to keep the name of the project confidential until after filming is complete.” (We’ve looked around a bit but haven’t found an obvious match yet.)

P.S. Our archives show a mention of similar filming back in 2010.
