The A465 will be changed to 2 lanes in each direction from Dowlais Top to Hirwaun.
For more information about this project, please see Welsh Government links on the right, for information on traffic management see details below.
Overnight closures of the A465 between Cefn Coed and Dowlais.
On each of these dates the road will be closed at 20:00 and re-open at 06:00 the following morning:
Monday 5 June 2023
Thursday 8 June 2023
For all other traffic wishing to travel between Rhigos and Merthyr Tydfil, the diversion will be via the A4059/A470 following the green route.
We apologise for any inconvenience these works may cause.
To complete these complex and long term roadworks, the contractor will sometimes need to:
- reduce the road from 3 lanes to 2.
- close sections of the road overnight or over weekends
- use traffic lights to control traffic flow during the works.
The speed limit has been changed to 40mph to protect the safety of road workers on site and the public. This will be enforced in the same way as the existing speed limit using average speed cameras.
Free recovery will be available for vehicles breaking down in the roadworks area.
The Welsh Government appointed Future Valleys Construction as their partner to help deliver the project. The South Wales Trunk Road Agent is not responsible for the maintenance on this section of the road.
Follow @TrafficWalesS on Twitter for the latest traffic management measures on this road. Enquiries about the works will be directed to the Future Valleys team.
