Councillors for that area & the surrounding areas, should be doing more/joining forces, to lobby the necessary bigwigs & organisations.
As was said above, it really should be dual carriageway to Shrewsbury as it’s the major route into the midlands and beyond. You only have be traveling south around rush hour to see the traffic built back all the way to Ruabon, purely due to volume of traffic because it’s narrowed down from dual to single lane, same can be said from the other direction I’ve no doubt.
Now the high bridge(s) are there, there’s no chance of it becoming one due to the cost involved, but it just shows up the false economy involved with original planning!
