Start Date: Spring 2021 | End Date: Mid 2025

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.

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. 

To report incidents or issues on the network, please call the A465 control room on 0800 865 4650. The line is available 24/7.
