Will the A455 be brought back from the dead or is this going to be given the inglorious honour of a 4 digit A-road?
I would prefer A455 - it's got to be something snappy otherwise people may be discouraged from using it.
I favour an partial solution which hasn't been discussed much. This is to close some of the motorway's slip roads through Newport - jcn 25 & 26. having 3 junction in little over 1/2 a mile is not needed.
Dear God no! People are always suggesting closing junctions as a solution to congestion. It may reduce congestion slightly on the motorway but it would increase it tremendously on city surface streets. There are half a million people in Monmouthshire. How would they access the motorway if all the junctions were closed?
I have lived in Newport
why not close some? .. and make the main access to Newport centre & suburbs via the new link road? FWIW I've always thought Newports road network to be bonkers, just full of rat runs and so many alternatives to getting on the M4 yet so many dead ends and such a mish mash of D2's fly-overs, suspension bridge, underpasses etc
So the Llanwern road will make a difference with that there even though the road from jcn 24 is good.
Except as I've already pointed out it dumps you onto the SDR with its roundabouts, traffic lights and 30 limits!
But the M4's limt is only 20mph higher...though your point about the roundabout is valid, it needs to be freeflow.
