Just been sent an email with the following information in it:
During last week, there were SPECS average speed cameras erected on the QE2 “Dartford” Bridge in Essex/Kent. They start just before the bridge and end before the tolls at the end.
If you have driven by and not seen them last week, it’s because they are mounted on a road gantry rather than on the normal yellow or blue poles.
Pictures here: http://btst.co.uk/QE2BridgeCameras/ (from 2 different spotters so that we got all the cameras)
Often there is a big delay between the cameras being put up and actually going live, but our source tells us they are going live this week.
The SPECS area on the other side of the road is also being extended but we understand that the extra cameras haven’t been cabled in yet.
