It was first called, the Deas Island Tunnel and then the George_Massey_Tunnel. Perhaps the new tunnel will be given a different name. This narrow tunnel has been a serious chokepoint for several decades. Apparently, there wasn't any proper big city planning, despite there being a ferry terminal & the Delta Port facilities.

Even the new tunnel will be symbolic or indicative of not having a train between the Delta ferry terminal and YVR. The new tunnel or crossing should have been built in 2 phases.
First, the two 4 lane sections for general traffic & buses. Then, as port & truck traffic increases, a train & truck tunnel or bridge should be built.
