Officially, there isn't suppose to be a backwards BC agenda. However, the Skybridge between NW & Surrey and the North_Arm_Bridge between Vancouver & Richmond, were designed too narrow. Unfortunatly, both of these SkyTrain+bridges weren't designed to have 2 bus lanes, or even HOV lanes. Key people knew that the SkyTrain wasn't going to be running 24hrs a day. Thus, there would have to be late-night busses when the trains shut down for the night. The 4 lane Pattullo+Bridge and the 4 lane Oak+Street+Bridge don't have enough space for 2 bus lanes, not even 1, let alone any HOV lanes. Therefore, if there is any traffic disruption on such narrow bridges, a bus will be blocked.
Both the Skybridge and The North Arm (Train) Bridge should have at least had a provision for 2 bike lanes & 2 sidewalks. But BC continually lacks having a proper transportation infrastructure vision.
It's amazing that there wasn't enough interested people to make sure that the Skybridge between NW & Surrey would have at least 1 bike lane & 1 sidewalk. It has neither, because the public was expected to just take their bikes on a single sidewalk that is narrower than some people's bathtubs on the old, inept Pattullo Bridge.
