The South Wales Trunk Road Agent (SWTRA) is charged with operating, maintaining and improving Wales' motorways and major A roads on behalf of the Welsh Government. We're working hard to improve driver safety and reduce congestion on this busy section of the M4.

What we've done so far
Since December 2019 we've increased our Traffic Officer recruitment by 60%. This will enable us to improve our response times and extend patrols on the A48 and A4810 in Newport. We're currently commissioning additional Traffic Officer vehicles so that we can roll out provision in these areas whilst working in dual vehicle convoy. This allows us to conform to social distancing rules whilst continuing to deliver the service.
Improving lane guidance & road surface on
M4 Westbound J25 Caerleon to J25A Usk River
Approximately 120,000 vehicles travel this busy stretch of the M4 each day. This project is crucial to improve driver safety, traffic flows and road users' experience.
In addition to renewing the carriageway surface, we will be providing additional lane destination markings to promote lane discipline. Advanced road markings in combination with the current signs will help to prevent late lane changes and will mean that road users will be given as much notice as possible to use the correct lanes.
For more information on the benefits of the scheme see video below.

What we'll do next
We've begun work to replace the existing variable speed limit with an average speed control of 50mph around junction 24 to 28 of the M4 and are currently following the legal requirements to put this in pace. Typically this process takes around 6 months and therefore should be completed by December 2020.
Once the new Traffic Officer vehicles are ready and traffic flows begin to return to normal levels we'll extend the Traffic Officer patrols to A48 and A4810 in Newport.
We'll update this page with the latest developments as well as our social media channels @TrafficWalesS.
Work to carry out essential carriageway maintenance works including resurfacing and lane markings to a 1km section of the M4 westbound carriageway between J25 Caerleon exit slip road and J25A Usk River exit slip road will commence on the 29/06/2020 for 10 nights (Mon-Fri).
