AVERAGE speed cameras on the A14 - now acknowledged as the most congested A road in Britain - are not expected to be operational until the end of the month.

The cameras are yet to be handed to police as testing and calibration work is carried out.

The cameras cover the stretch of the A14 between the Spittals interchange and Girton.

According to a national survey of A roads carried out by jointly by Trafficmaster and the RAC foundation, the stretch of the A14 between Huntingdon and Cambridge is a "notorious bottleneck".

The report said there was no one solution to the problem, saying a "package of measures" was needed, including improved public transport.
