The Steel_Bridge and the Washington_Avenue_Bridge, if only such bridges were allowed in Greater_Vancouver...
The Steel-Bridge is old, yet adequately functioning as a multi-model crossing.
Upper: 2 outer lanes for general traffic, 2 inner lanes solely for MAX Light Rail, and sidewalks on both sides
Lower: Union Pacific Railroad (incl. Amtrak toward Eugene) and walkway.

"The bridge has two decks, with the lower deck designated for motor vehicle traffic and light rail trains and the upper deck used for pedestrians and bicycles (lanes specifically for bikes are on the north side)." https://en.wikipedia.org/wiki/Washington_Avenue_Bridge_(Minneapolis)
Unfortunately, the Skybridge between NW & Surrey, has no bus & bike lanes. Thus, its another fine example of backward BC planning. https://en.wikipedia.org/wiki/Skybridge_(TransLink)
Even though the SkyTrain wasn't intended to run 24hrs, no adequate future capacity provisions were included into the design of the SkyBridge. Ideally, the bridge should have had at least 3 tracks on 1 deck. Plus, 2 bus & bike lanes on another deck, with 2 lanes for emergency vehicles that would all be open 24-7.
Apparently, it was better to funnel everything into the inept Pattullo_Bridge. A narrow 4 lane joke of a crossing with only 1 narrow sidewalk. Its so nice that the Sydney-Harbour-Bridge has 2 pathways. Surrey is set to become the largest city in BC. Thus, Surrey & NW should have had several bridges like Portland_OR by now.
In the 1930s, NSW already had a sense of Sydney being a substantial state capital on the Pacific for quite a while. In contrast, NW, BC emphasized its status of a former backwater provincial capital & perpetuated its small-minded city mentality.
Thus, the Sydney_Harbour_Bridge was originally built with six lanes, 4 sets of tracks & two sidewalks. Where as the Pattullo_Bridge was a fine example of backwater BC thinking & planning. Unlike the impressive Sydney_Harbour_Bridge, there is no comparable high level bridge in BC which is capable of carrying double deck passenger trains. Of course it should be noted that NSW has seen itself as a mighty state on the Pacific for quite a long time. Thus, the 1930s Sydney_Harbour_Bridge remains so far ahead of anything in backwater provincial BC.
https://en.wikipedia.org/wiki/Sydney_Harbour_Bridge_cycleway Unlike the BC aproach, NSW didn't have to remove any traffic lanes. Ultimately, Vancouver will have traffic lanes removed from 3 of its bridges, because the city refuses to build anything like the magnificent Tilikum_Crossing in Portland, OR. Vancouver was one of the first cities to get rid of its streetcars & will likely be one of the last to ever bring them back. Well fortunately, there was nothing like the BC mentality to stop the Portland_Streetcar_or_the_Tilikum_Bridge.
The tram-train MAX_and_bus_on_Tilikum_the_Crossing. If only backward Vancouver, BC would allow such a fine transit bridge, then there would be less congestion on the existing narrow bridges. Indeed, Greater Vancouver refuses to build a series of bus-bridges, even though that would relieve some of the regional congestion.
Unlike in the largest urban area in BC, Portland,_OR was able to build many more bridges.
https://www.pattullobridgereplacement.ca Of course the bridge wasn't built with the provision for a lower deck similar to what's on the Tilikum Bridge. https://www.pattullobridgereplacement.ca/about/projectoverview It wasn't allowed to have 8 lanes like the Anzac_Bridge_in_Sydney. So no bus & HOV lanes, just have everything crammed into a 4 lane bottleneck. No emergency lanes, it will open with only 2 lanes each way, but with the potential to become a 6 lane bridge, some day. So, just like the Skybridge, it won't have 2 dedicated bus lanes.
Unlike the Skybridge in NW, at least the North-Arm-Bridge to Richmond has 1 bike lane, but there should have been 2 as well as 2 bus lanes & even 2 emergency vehicle lanes on the North_Arm_Bridge. Since the North_Arm_Bridge doesn't have 24hr train service & no bus lanes, late-night buses only have the 4 lane bottlenecks that are the Oak_Street_Bridge, Knight_Street_Bridge & the Queensborough_Bridge. Of course there are no emergency vehicle lanes, because even they should be subjected to the overall congestion of the region.
The Sydney_Harbour_Bridge, the Anzac_Bridge & the Tilikum_Crossing were all possible, simply because they aren't subjected to anything like the restrictions impose in Greater_Vancouver or BC in general. The BC part of Canada is trapped in some kind of a stagnation loop or a series of restrictions to stiefel or thwart infrastructure upgrades & progress. However, so many other cities around the world just aren't subjected to anything like the BC approach to things.
