When the Queensborough_Bridge opened in 1960, there wasn't any serious consideration for future capacity. The QB should have had 2 wide shoulders and 2 wide emergency lanes. Then, by the 1980s 2 bus lanes could have been opened. Then, by around 2000 the QB could have had 3 lanes each way, plus 1 bus lane each way.
https://en.wikipedia.org/wiki/Queensborough_Bridge Unfortunatly in 2026, the QB remains as a 4 lane funnel. Just 2 lanes each way as its another classic BC bottleneck-chokepoint, by design. There is enough space east of the bridge for a new northbound bridge to be built.
New_Westminster has always been a small city, because it never absorbed what would become the Tri-Cities. Thus, a narrow QB fits in with such a little provincial backwater. However, as part of the BC Lower_Mainland its part of a region with over 3 million people. This puts NW in the position of being a regional hub city.

Bike+bridges aren't a problem in many Australian cities and around the world. However, as usual, its more difficult to get such things done in backwards BC.
