A landslide occured near Shellbird Island. The highway was closed for several hours. It covered an area of approx 10 metres of horizontial extent down a 6-8 metre embankment on top of which was the CN railway line. It involved an estimated 100 cubic metres of material, and the local stratigraphy showed 2 metres of gravel over a silt/clay-rich unit. It was caused by a build up of water behind the tracks that seeped onto the gravel unit, and failure occured along the contact.
