Either a new bus, HOV & train bridge has to be built, or a new much wider Iron Bridge is essential.
https://en.wikipedia.org/wiki/Samuel-De_Champlain_Bridge A nice 8 lane bridge with 2 train tracks was possible in Montreal, because its far away from the stunted infrastructure agenda of Vancouver & the backwater BC mentality. Any new Iron Bridge should be at least as wide as the New_Champlain_Bridge_in_Montreal.
Of course people from Vancouver are allowed to visit Montreal, but the backward BC mentality just isn't allowed to take over Quebec, Ontario or Alberta.
