The Pattullo Bridge saga in BC
The old Pattullo_Bridge was built with a narrow sidewalk on only one side & a road deck that can barely hold 4 narrow lanes. It's all part of the narrow mindedness of the BC mentality.

"The new Pattullo Bridge is on track for completion in 2024, but business leaders in Surrey are calling for six lanes to be open to vehicle traffic on day one, instead of four as currently planned." https://globalnews.ca/news/9489375/pattullo-replacement-six-lanes-debate

https://604now.com/like-cross-pattullo-bridge-1937 Why build a wide bride that also has 2 wide sidewalks when the bare minimum can be done instead? Then try to build an inadequate replacement bridge with only 4 lanes, no bus & HOV lanes & no emergency lanes. That's the BC way in the 1930s & the 2020s. At least it will have a couple of bike lanes.

Wide+bridges, twinning or duplication can allow for express bus lanes and more HOV_lanes in general.

https://www2.gov.bc.ca/assets/gov/driving-and-transportation/reports-and-reference/reports-and-studies/frontier_to_freeway.pdf It was quite a thing for BC to have waggon roads & then eventually some were doubel width. Unfortunately, even today, there is a mentality to just have 1 or 2 lanes each way. Yet, such thoroughfares will be marked as a major route when it's not much wider than a country road.

Multimodal Bridges and Tunnels
There used to be a time, especially in the mid 20th century, when several bridges were built with narrow sidewalks, or none at all. Forget about emergency lanes & especially not allowing for bus & bike lanes. Just have the crossing get all plugged up, so you are still punished, even if you use public transit.

https://www.bloomberg.com/news/articles/2014-08-19/why-portland-is-building-a-multi-modal-bridge-that-bans-cars This is one of the best bridges of its type in the world. The Interstate bridges in downtown Portland,_Oregon have no bike and pedestrian access. However, the Tilikum_Crossing was intended to be a nice counterbalance. https://en.wikipedia.org/wiki/Tilikum_Crossing#Design
https://en.wikipedia.org/wiki/Providence_Bridge_Pedal
Vancouver, BC could have really benefited from something like the Tilikum_Crossing_in_Portland. However, no such streetcar or tram-train bridge exists in Vancouver, BC. Fortunately, Portland & Seattle were able to revive some of their old streetcar lines. Cities like New Orleans, Philadelphia, Boston, Toronto, SF & Melbourne retained some of their streetcar or tramlines, unlike Vancouver.

The George_Massey_Tunnel in BC, Canada is a sad joke. It wasn't designed to accommodate 2 bus & bike lanes. No footpaths & no emergency lanes. It is a fine example of BC bottleneck planning. The Louis-Hippolyte_Lafontaine_Bridge-Tunnel in Montreal, is slightly a little better.
https://www.highway99tunnel.ca While this new tunnel will have 2 bus - HOV lanes & a bike path, there is no provision for a train connecting the airport to the ferry terminal. https://www.delta-optimist.com/local-news/interurban-rail-not-on-the-horizon-for-delta-6448841 This means that eventually some day, a new train tunnel or bridge will have to be built to provide a rail link between the Tsawwassen_ferry_terminal and the Vancouver_International_Airport.
Some day, when enough sensible people can implement proper big city regional planning, a train could run from Waterfront_station_(Vancouver) to the Park_Royal_Shopping_Centre and onto the Horseshoe_Bay_ferry_terminal. Unfortunately, backward & slow-moving Vancouver is only just starting to think about having its own version of a North_Shore_railway_line.

Whether its for environmental reasons or just for overall efficiency, transportation corridors that are designed for various modes of of transit, can effectively move more people.
