Of course there still seems to be no plan to build a bus and bike bridge next to the Arthur+Laing+Bridge.
Unfortunatly, the embarrassment that is the Canada+Line wasn't designed to eventually have 10 car trains, not even 5. It's stations can only accommodate a ridiculous 2.5 car train, some day. Thus, any bridge to and near the airport should be augmented with a bus and bike bridge. Especially since the C Line isn't open 24 hours. Apparently, it's better to just cram everything into the ridiculously narrow 4 lane bridges.
