I’ve just travelled along the A25 from Reigate to Dorking and there are new average speed cameras from the roundabout on the A25 from the B2032 Station Rd into Dorking 40MPH, used to be mostly 50’s. Also poles but no cameras yet from Buckland past the Shell garage to the roundabout as above.
A24 south of Dorking now also has a stretch with average speed cameras. Limit is still 50 as it was before but it is mighty tedious to ride/drive on.
