The Alex_Fraser_Bridge should have opened with 8 lanes with enough width to eventually have 10 lanes. Plus, 2 wide bike lanes and 2 footpaths. A wide emergency lane or wide shoulder that could have eventually become 2 bus lanes.
https://en.wikipedia.org/wiki/Alex_Fraser_Bridge So, instead of an ultimate design of 10 lanes with 2 emergency lanes and a provision for a lower deck, everything was squeezed into only 2 lanes each way. There wasn't even enough planning logic to have a wide shoulder or wide emergency lane on each side in the first phase of construction. It was an instant classic 4 lane BC bottleneck-chokepoint.
Fortunately, there was at least a provision for it to eventually accommodate 6 lanes and ultimately, a 7th lane was squeezed in. Its still a far cry from being 12 lanes wide or having a lower deck.
The British_Columbia_Highway_91 should have been properly been built as an effective bypass to the joke that is the 4 lane George_Massey_Tunnel chokepoint. The H-91 and the Alex_Fraser_Bridge should have had 4 lanes each way, plus a bus lane each way. Especially, since there is no train along that corridor and there still isn't enough government interest to have a train next to the George_Massey_Tunnel-Replacement. While the new tunnel will have a bus lane each way, there is no provision for a train tunnel or bridge. This isn't just another case of BC planning shortsightedness, its indicative of the BC Mind Virus.
The BCMV isn't supposed to be real, but something like it always seems to show up whenever there is a chance to build some proper big city size infrastructure.
