A public consultation exercise on options for improving the capacity of the M4 corridor around Newport opened on 5 March It lacks continuous hard shoulders, has closely spaced junctions with sub-standard slip road visibility and narrows to a restricted two lane section through the Brynglas Tunnels. Heavy congestion occurs along this stretch and either side of it at peak hours.

There have been calls to close the slip roads at Junction 40 and 41 at Port Talbot to improve traffic flow. The motorway has only two lanes on this stretch and is a major traffic congestion blackspot.

Junctions 40 and 41 at Port Talbot have very short slip roads which have not been modernised. In future, it is hoped to extend the M4 to Carmarthen, but this depends on finance.
