https://www.alberta.ca/south-bow-river-bridge Being from backwards Vancouver, its difficult to grasp how Calgary was able to twin the South-Bow-River-Bridge. Not only are there 8 lanes, but at least 2 emergency lanes.
https://en.wikipedia.org/wiki/Stoney_Trail#Lane_count In BC, it was tough enough just to have 2 waggon roads side by side. Then to eventually have a bridge the width of 4 waggon roads or 4 carriageways, was amazing. Fortunately, Calgary has progressed so far beyond the 1800s & the early 20th century.

https://majorprojects.alberta.ca/details/Stoney-Trail-SE-Bow-River-Bridge-Widening-Pedestrian-Bridge/4312 There have been a lot of complaints as to why it took so long to compleate this project. While backwater BC notoriously takes longer to get things done than Alberta usually does, there might have been an issue with the river. Still, after any environmental assessment, the construction project should have gone faster.

A fantastic foot and bike bridge is close by and unlike in Vancouver, lanes were added, not removed. Indeed, the Calgary footbridge and The+Helix+Bridge in Singapore were never used as an excuse to remove any lanes from other bridges. The same for the Jubilee+Bridge.
https://www.highway99tunnel.ca/frt-current-work The environmental assessments while necessary, have pushed this BC infrastructure project to at least 2030. https://www.highway99tunnel.ca/project-overview-frt Several decades ago, another tunnel or bus & bike bridge should have already been built. https://www.highway99tunnel.ca/transit-cycling Unfortunatly, when the first tunnel was built, there was no concept to have 2 bus & 2 bike lanes with 2 protected walkways. No need to have 2 wide emergency lanes with a future clearance to allow for 2 truck lanes, given that this is supposed to be a major seaport region. Just funnel everything into 2 lanes each way, whenever possible.
