I have just been down the M6 and noticed that there are traffic lights albeit covered, on the sliproads of J's 22 & 23.

I read somewhere last month that someone had a brainwave and suggested holding up the traffic feeding onto the motorway during peak hours - and it looks like it is coming to fruition, but is it a brilliant scheme or will it cause mayhem?

For the traffic already on the motorway, I am sure that there will be a slight benefit but I can see local traffic backing up to and past the roundabouts that feed the slip roads preventing vehicles from travelling over or under the motorway on the ajoining roads
