The reef, which spans about 1,800 square metres, at the Lynn Creek Estuary in North Vancouver, was completed earlier this month in a partnership between Neptune Terminals and the University of B.C.

Matt Simmons, execution planning lead for Neptune, said four barges worth of rocks — about 4,000 tonnes — travelled by barge and tug from Sumas Mountain in Abbotsford to the terminal for the reef, which is intended to create a more complex habitat for marine life down in the reaches of the estuary.
