https://en.wikipedia.org/wiki/North_Arm_Bridge This is supposed to be a vital modern connection between Vancouver, YVR and Richmond. Yet since 2009, only 2 car joke trains go over it and there is only 1 combined bike and foot path.
This strange bridge wasn't designed to have 2 express bus lanes, even though the YVR train service isn't open 24 hours. Even more strange is that there aren't 2 bike lanes and 2 sidewalks. Its all just crammed into one narrow path on the west side of the North Arm Bridge.
The Knight+Street+Bridge, Oak+Street+Bridge and Arthur+Laing+Bridge, are all 4 lane chokepoints. These bridges are so narrow, there isn't enough space to have 2 bus lanes on them. An express bus-bridge should have been built next to all 3 bridges.
https://structurae.net/en/structures/north-arm-bridge This bridge really should have had 2 express lanes or 2 BRT lanes, but Greater Vancouver doesn't seem to be that interested in having a proper regional BRT network, despite no 24 hour train service..
