Ringway Road and Ringway Road West near Manchester Airport are partly 40, and partly 50. A couple of years ago, due to some work at the airport requiring traffic to be diverted, they slapped a temporary 30 limit on the 50 stretch, and part of the 40 stretch, and put in a mini roundabout. The original limits were restored a few months ago, and new signs were erected at the point where 40 changes to 50. On both sides the speed limit posted was 30.
It was like that for months before anybody did anything about it. BTW didn't that make both speed limits NSL, as the signage was incorrect?
As fr Brunstrom's lot, they had it coming to them. I speak as one done for doing 35 in a 30 on Anglesey a few years ago.
