Traffic congestion

I often come across a traffic congestion when coming back to Downtown from the airport. I think the largest reason for the jam is bottlenecks. As you know Greater Vancouver is divided by rivers or creeks and we need to cross a bridge or pass a tunnel in order to move from here to there. Those special points often change into bottlenecks because they have only limited lanes and cannot hold too much traffic. Furthermore, in rainy days, there often occurs traffic accidents. Traffic accidents at one of the bottlenecks leads to the worst case scenario. The traffic sometimes stops completely for hours. I don't know the best solution for this traffic congestion but it is no doubt that the infrastructures of Vancouver cannot hold the increasing cars any more.
