Drivers who use the airport tunnel in northeast Calgary should be aware of closures over the next few days to accommodate a movie shoot. The westbound lanes were closed at 5 a.m. Monday and will stay closed until Wednesday at 5 a.m., then the entire tunnel will be shut down until Thursday at 9 p.m. Officials haven't said which production is causing the shutdown, but the HBO series The Last of Us has been filming around southern Alberta in recent weeks. The six-lane airport tunnel connects Barlow Trail to 36th Street N.E.
