O P Just out of interest, can you remember if you stopped at the traffic signals under the flyover ?
I've come down there and been on a green and sailed through with buses etc and it could be easy to miss the signs. Just thinking that sitting there on a red would give time to look across into the new road.
The signs are perfectly legal and the roundals on the floor don't even have to be there as a speed limit sign has to have a red circle on it and be specific sizes etc. They are there to make drivers more aware.
Everyone is human and I think we can all take some advice from this thread and prevent us going too fast.
