Eventually, 2 lanes were removed & the lower deck was never completed. However, Vancouver was unable to prevent Seattle & Portland from reviving some of their streetcar routes.
The problem isn't bike lanes, it's the lack of interest to build a proper regional network of bus & bike bridges. Thus, if a proper bike bridge was built next to the Burrard+Street+Bridge, then 2 of its 6 lanes could have been for buses or at least HOV lanes. The lower deck could have still been for streetcars or tram-trains going between Vancouver & Richmond. The irony of backwards Vancouver is that it was one of the first cities to get rid of its streetcars & will likely be one of the last to bring them back.

Of course the new Richmond-Delta+Tunnel wasn't designed to be part of a rail link between the airport and the ferry terminal. There should have been 2 HOV lanes, as well as 2 bus lanes, but that would be a big-city 10 lane crossing. Instead, just an 8 lane tunnel with no train component. Eventually, a train and HOV bridge or tunnel will have to be built next to it.
At least the first SkyTrain line can now have 5 car trains. However, the 2 car joke of a train still exists between Vancouver & Coquitlam, as well as between Vancouver & Richmond. The Montreal Metro can have 9 car trains and BART in SF can have 10 car trains. Such things are possible because they don't have a congestive BC panning mentality.
