Council Officers have been checking and observing the situation with the Church Road bridge traffic signals. There is no fault on the sensors. They are still of the view that the problems have occurred when heavy traffic is accompanied by a vehicle crossing on red. The sensor then reacts by going into "safe mode" which reduces the the green time on the following cycles.
If after monitoring the situation this evening they believe the problem will continue they will be switching the signals to manual during peak periods on Monday.
