Of course with all the extra cost, there still won't be an LRT tube and no HOV lanes. While the new tunnel will be 4 lanes each way, there should have been an extra section for 2 LRT tracks and 2 rapid bus lanes.
A 10 lane version of an Alex_Fraser_Bridge with a provision for LRT, could have been completed a few years ago. However, just because some people didn't want a bridge crossing that part of the river, the plan was scrapped. The result is more cost and delay in what should have been completed a few decades ago.
If ever a proper LRT and rapid bus crossing can be built parallel to the new tunnel, then that 8 lane tunnel could still have 3 general lanes each way, plus the 4th being an HOV lane. A parallel LRT and rapid bus needs to be built between Richmond and Delta so that there can be an efficient connection between YVR and the 2 ferry terminals.
Something like a Tilikum_Crossing between Richmond and Delta should have already been built decades ago, but there just isn't proper transportation planning in backwards BC.
Either an extension of an improved YVR-Canada Line, or and LRT like the C Train or MAX_Train. Since such a train wont be running 24 hours a day, there would need to be a Rapid articulated_bus_crossing as well. Such redundancy is important, especially if there is an occasional problem with the train. A Streetcar_Crossing would also be nice, because the Skytrain, LRT and rapid bus can't go everywhere. Where as express and local buses and streetcars can fill in the gaps.
Of course more bicycle and footpaths can be a great improvement.
