It's unlikely that the BSB will ever be restored or completed, because of the Vancouverization mentality.

The city was too cheap to build a nice, wide bike-bridge next to the BSB.

Thus, instead of removing 2 lanes, the BSB could have still had 6 lanes, which 2 lanes could have been for buses. Then a lower deck for 2 streetcar tracks.

A 6 lane bridge with 2 streetcar tracks & a parallel bike-bridge, is just too advanced of a crossing for backwards vancouver.
