The Lions+Gate+Bridge has been the quintessential, multigenerational symbol of backwards Vancouver planning. While there are a couple of nice bike lanes & sidewalks, the 1 deck bridge is too narrow for an efficient express bus & train crossing. This is a crossing that should be on a grand scale like The Sydney_Harbour_Bridge and Harbour_Tunnel. However, the Vancouver version would focus on the tunnel portion.

By now, there should have been a 6 lane highway tunnel, plus 2 dedicated express bus lanes and at least a double track train tunnel. Then the LG Bridge could remain as a very nice bike & foot crossing. Unlike Vancouver, Sydney, SF, Seattle and Montreal don't use water as an excuse to hold back the cities scale of transportation.
