A bridge so narrow that it should have only been a foot & bike crossing by now.
The inept Lions+Gate+Bridge should have had an 8 lane tunnel under it several decades ago.
Georgia_Street through most of the downtown is 6 lanes wide, but as you get closer to Stanley Park, its 7 lanes wide. Thus, an 8 lane First_Narrows tunnel could have easily been constructed.

While the likelihood of Georgia_Street feeding into the Georgia_Viaduct connecting East Vancouver & Burnaby with a freeway is no more, Georgia_Street could still feed into a Stanley Park tunnel.
There would be no need for a freeway through the downtown, as a tunnel would simply provide a high capacity crossing. 3 lanes each way, plus a bus & HOV lane each way & even a provision for rapid rail transit.
The stubborn city chooses to do nothing with the First Narrows. However, at least some serious planning has started for the Second_Narrows upgrade or replacement.
