Speed cameras have been installed near the Sheppey Crossing - but are not being used to penalise drivers.

Highways England fitted the average speed devices at either end of the bridge last week.

However, the government agency said that at this stage they are only being used to monitor traffic flow.

A spokesman said data collected from the cameras was not being used to issue fines or tickets of any kind to motorists - something it has no power to do.

He added: “Safety is our top priority and our objective is to ensure safe and reliable journeys for the 30,000 drivers who use the A249 every day.

“We have listened to feedback from drivers and installed average speed cameras to better monitor the reduced speed limit.”

But in an email to MP Gordon Henderson yesterday, Highways England state they can be used by police to take action against speeding drivers.

District commander, Chief Inspector Tony Henley, also previously confirmed there would be speed limit enforcement on the bridge in the future, but added it would not be his officers doing it.

Mr Henderson said: “If you are going to have a speed limit - and I’m not convinced we need it - but if you’ve got one, it has to be enforced or it’s pointless having it in the first place.

“The only way you can enforce the limit is with average speed cameras, so I’m glad Highways have installed them and it’s up to police to decide to use them.”

It is thought average speed cameras are being used instead of regular ones because of legislation outlining the type of signage and distance between signs for the enforcement of temporary speed limits.

Because of its design, the Sheppey Crossing cannot have any signs or other devices installed on it.
