Ramp metering has been introduced on the slip road leading to the M60 (the Manchester outer ring road) from the roundabout at the junction with the M67. At rush hour, the lights come on and dribble one or two cars every thirty seconds onto the M60. However, the queue of traffic then backs up the slip road, and onto the roundabout, completely jamming it. It is illegal to join a clogged roundabout, when the intended exit is obstructed e.g. by a queue of cars. However traffic joining from the A57, from the direction of Manchester, is unaware of the obstruction unless they have been paying very careful attention to traffic reports on local radio stations, which are also marked by diabolically irritating jingles, presenters and music selections.
