Of course when Vancouver & the greater urban region became obsessed with keeping the roads & bridges narrow, it was as if there wasn't a proper concept of express bus lanes & rapid bus lanes.

The 1959 George_Massey_Tunnel should have opened with 3 lanes each way. Plus, 2 wide emergency lanes. Then over the course of its first 2 decades, it could have become a 6 lane crossing with 2 bus & HOV lanes.
By the 1980s, the inept 4 lane George_Massey_Tunnel should have had a parallel higher & wider bus & HOV tunnel consisting of at least another 4 lanes & at least 2 emergency lanes. Thus making it more capable as an eventual replacement to the old tunnel. Then by around 2000, there should have been a bike, truck & train bridge or tunnel as well.
A George_Massey_Tunnel#Replacement by 2030? The first phase of this really should have been started by the 1980s. Of course the new tunnel with 8 lanes & 2 bike lanes, won't have 2 emergency lanes & there won't be 2 truck lanes. Plus, in accordance with a perpetual congestive planning mentality, there is no provision for an extension of the Canada Line with its inept 2 car trains.
The new tunnel should have had 3 general lanes each way, plus 1 bus lane & 1 truck lane each way. Plus, 2 wide emergency lanes which could eventually be repurpose for a north & southbound rail rapid transit corridor.
That's because someday the Canada Line can not only have 2.5 car trains, but an actual 5 car train consisting of five 20m coaches. Selective_door_operation technology would make this possible. Of course it would have simply been much better to have designed all the stations to already be at least 100m, instead of the inept 50m. Unfortunately, backward BC thinking keeps getting in the way.

Keeping the old tunnel as a freight corridor between Delta & Richmond would be of tremendous benefit. Delta has the Roberts_Bank_Superport & the Tsawwassen_ferry_terminal.
Richmond has the Vancouver_International_Airport & the inept Canada_Line.
Despite budget limits at the time, the Canada_Line should have been designed to eventually have 5 car trains & ultimately, 10 car trains. It should have been envisioned as a high capacity rail link between downtown Vancouver, YVR, Richmond & Delta. With an ultimate connection between the Tsawwassen_ferry_terminal and the Horseshoe_Bay_ferry_terminal.
For some reason Vancouver & BC never seemed to really take off in the 1980s like Calgary, Seattle & Perth. Indeed, while Vancouver seemed to continue on its sleepwalking path after Expo_86, Brisbane really started to boom after its World_Expo_88.
Unlike SW BC, the Brisbane Airport & seaport are much closer to each other.
https://upload.wikimedia.org Being from Vancouver, its difficult to grasp how Brisbane was ever allowed to permit such nice long trains. This is something to be very proud of, as it can move a lot of people in both directions. https://en.wikipedia.org/wiki/International_Airport_railway_station,_Brisbane This opened in 2001 & Vancouver's inept version had to be ready by 2010 with just 2 car trains. Yet, Brisbane designed their to be high capacity capable as soon as it open for service. From a backwater BC perspective, it's amazing how Queensland is able to think on such a grand scale & to properly allocate the necessary funds. Who knows where so much of the funds went in BC? That's because not enough of it seems to have gone into the infrastructure.

https://en.wikipedia.org/wiki/Sir_Leo_Hielscher_Bridges This has the potential to still have 4 lanes each way. Plus, 1 bus or HOV lane & 1 truck lane each way.
