The Point to Point speed cameras are already on the M4 in sydney between the cumberland Highway overpass and the bridge that goes over church street. They arent very easy to spot though, on the cumberalnd highway overpass, they are almost tucked up under the advertisement sign on the bridge, as you approach look up, your on camera . they look like the digital cameras in the bottom pic of the below link. The second set of cameras is on the existing safe-t-cam and variable speed limit sign framework just on the beginning of the bridge over church street. As the site mentions the cameras are only on the eastbound route. Theyve been very tricky about installing these cameras and hiding them, and legally they need not add extra signage drawing attention to them as they use the speed camera warning signs for the cumberland overpass speed cameras to cover their asses (hence only eastbound). They really didnt want anyone knowing what they were up to till its too late, as the website states they will be activated ~june 2005.
