I know we've discussed this at length before, but I can remember many examples of signalised junctions in NSL areas going back to the mid-60s.
As long as that? Really? I knew that there were some, especially in the Manchester area, but I had no idea they went back that far.
I'm pretty categorical that in London and the south there were none before about 1985 - and there aren't very many now.
There's one
here at a skew bridge in the Thames Valley (well, not a junction, but anyway). There have definitely been lights there since the early 80s, and I reckon they must have been there for quite a while before that (there would have been no other way of crossing the bridge, since it wasn't wide enough for two cars, and you couldn't see what was coming). There's been a bridge there for a very long time (a replacement was fitted recently, which is actually two lanes wide, but they kept the lights for safety reasons due to the alignment).
It's in an NSL, but since people have to slow right down for the bridge anyway, you don't get the problems that you normally would.
There are also long-time NSL lights on
this bridge a few miles north on the same road. Again, you have to slow down for the bridge anyway (because it's humped), although not by as much. (Incidentally those lights are pretty pointless because you can see exactly what's coming.)
Presumably there are many more examples of NSL lights where the road narrows temporarily for a bridge. So you can't always say that lights in speed limits above 40mph are bad, although I agree that they are where you could (on green) safely go through the junction at the speed limit.
And besides, anyone who's worried about lights on NSL roads should relax: soon there won't be any NSL roads left to put lights on.
