Each year, thousands of visitors come from all over the world to experience the wonder that is a B.C. salmon run.

This summer, we won't even have to leave the city to see this natural phenomenon.

Beginning June 23rd and running until late September, 5 nights a week, digital imagery of migrating Pacific salmon will be projected on the undersurface of the kilometre long Cambie Bridge. The installation "brings the heart of the BC river right into the heart of the city", as the media release puts it.

Viewing is from Coopers' Park / Marinaside Crescent at the north end of the bridge, for a standing capacity of 800 people. It's free and family friendly, and there is an accessibility viewing area.

'Uninterrupted' runs Tuesday - Saturday (except during Celebration of Light fireworks) and starts at 10pm and then, beginning August 15, at 9pm. Each projection lasts 25 minutes, with original score (no narration).

A companion website at uninterrupted will extend the experience by connecting site visitors with stories of people working to restore salmon habitat, places to see salmon in the wild, and ways to get involved.

Vancouver filmmaker, Nettie Wild, was inspired to do the project by a visit to the Adams River during a peak salmon run. Joining Nettie on the project are producers Betsy Carson and Rae Hull, who have earned international accolades for their innovative work in media.
