A VIDEO has been released showing exactly how the new improvements at J28 of the M4 will work once the project has finished.

Construction on the Welsh Government’s massive £4 million M4 J28 Improvement Scheme started in February 2017, and the project is said to be on target for completion in September this year.

On August 8, a through road allowing traffic to flow through a new single direct lane from the M4 J28 eastbound off-slip and the A48 from Cleppa Park, to the A48 towards Newport, was opened.

Next, on August 23, Costain are planning to open up the central drive-through on the Pont Ebbw roundabout, meaning two-way traffic will be able to travel along the A48 between Tredegar Park roundabout and the Southern Distributor Road.

The system of three roundabouts, including the already-finished Bassaleg roundabout, will be linked by intelligent traffic lights, say Costain, which will be able to learn the patterns of traffic flow and adjust accordingly to keep traffic moving.

But Costain have previously warned the system won’t be fully effective until all three roundabout works have been finished and it has had a chance to learn the traffic flow patterns.

Now, the Welsh Government has released a short video, which shows exactly how the improvements will work.
