False. The reason why Shoesmith Bridge is a problem is that traffic queuing is backing up onto it from Hill Street Intersection for northbound traffic. To a lesser extent southbound traffic is backing up from the single lane south at Woodcocks Road traffic signals.
As a rule of thumb if you stop traffic at traffic signals, you need two lanes of queues for each lane of through traffic. Most of SH1 is 2 lane thus there should be 2 lanes of queues at the signals each way.
True. It is a constriction for the waves of traffic at Whitaker Road traffic lights trying to merge, but it is not a cause of the congestion at Hill Street.
