Electrician I know told me a few traffic cameras have gone live .He says look out for yellow top on the Grassy Knoll at the Junction of Con Colbert and Johns Road inbound .It has been designated a dangerous Junction since Non 1st .That camera now takes photo of Speeding drivers and Box blockers .Junctions and roads are assessed as Dangerous depending on the amount of accidents or obstructions recorded within a certain distance .If they are designated then extra enforcement will be applies.There is also a new camera on the Long Mile Walkinstown Avenue Junction though I could not see it .
