Of course Vancouver won't build anything like the Boorloo_Bridge for bikes & pedestrians. Apparently, it's much better to take a lane away from the Cambie Bridge.
Fortunately, the backward Vancouver mentality never made it over to Perth. Otherwise, the The_Third_Causeway bridge would have had 1 or 2 lanes removed.
With 6 lanes, The_Causeway_in_Victoria_Park, Perth provides a nice 6 lane crossing. Unlike backward Vancouver the Causeway in Perth was allowed to have 3 lanes each way. The key component is that the 3rd lane each way is for busses. In contrast, absurd Vancouver won't allow for a proper bus & bike bridge network to be built, because it would rather keep its bridges as narrow & congested as possible.
Apparently, Vancouver has no plans to build something like the Boorloo_Bridge or the Esplanade+Riel+Footbridge next to the Cambie & Burrard Bridges. Thus, the Cambie has lost a lane & the Burrard has lost 2 lanes. Had both bridges been allowed to retain 6 lanes, they both could have provided 2 bus lanes.
The Cushing+Bridge is a 4 lane bridge in Calgary. Thus, like the Oak Bridge & Knight Bridge in Vancouver, there was no room for 2 bus lanes on them. Unlike, backward Vancouver, Calgary was able to build a 2 lane bus bridge right next to its Cushing Bridge.
Fortunately, the horrible transportation planning mentality of Vancouver was never adopted in Perth & Calgary. Either you have a wide enough bridge for busses, or you build bus & bike bridges to help the existing bridges.
The Norwood+Bridge in Winnipeg provides at least 6 lanes, so a couple of bus lanes isn't a problem.
Singapore built its Helix_Bridge instead of removing lanes from the other bridges.
