Frank Bird, emergency planning officer for the Agency in the West Midlands, said everything was being done to try and alleviate congestion, but such a large event would inevitably lead to some delays.“We are working with police and the NEC to do all we can to minimise disruption and delays, but there is only so much we can do when extra traffic is expected to converge on the area for the event.“The fair gets underway on Sunday and we expect that and Monday to be the busiest, especially during the morning and evening peak times. We will open the hard shoulder on the M42 for longer than normal each day until Thursday to enable extra capacity, but queues are expected.“If you can possibly avoid this area then please do, but if you need to catch a flight please plan carefully and allow longer for your journey.”It is anticipated that 3pm until 7pm each day will be particularly busy around M42 junction 6 until the event ends on Thursday.
