Vancouver Island fixed link
The Vancouver Island fixed link is any of various proposals to construct a fixed link by bridges, tunnels, and/or causeways across the Strait of Georgia, which connects Vancouver Island to the Lower Mainland of British Columbia. The strait has a minimum width of approximately 19 km between Galiano Island and the Tsawwassen Ferry Terminal, but a connection would need to be 26-29 km long to avoid entering US territory.
