Earlier today, September 23, Bucks Council confirmed that the traffic lights, maintained by National Highways, were not working and that the agency was awaiting parts to restore the lights. National Highways stated: "We identified an issue with one of the traffic light controllers on Sunday morning, which meant some of the lights at the roundabout weren’t working. Comments, attached to reports on FixMyStreet, stated that 'only half the traffic lights are working' at the roundabout, which has junctions with the M40 and A404. A further report said: "Traffic lights on two exits of the roundabout are not working. National Highways has been contacted for comment.
