Are you aware of the serious traffic problems at Apex Corner N.W.7 since the re-phasing of the traffic lights. The phasing at Mill Hill Circus and Apex Corner have recently been changed and they seem to be out of synchronisation creating mayhem for most of the day. There are constantly long queues of traffic going down to Mill Hill Circus and the roundabout is gridlocked. This occurs at various times during the day including outside of rush hour. Will you have the phasing urgently reviewed?
