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.
Hirwaun to Cefn Coed 02/09/22 - 05/09/22
A full weekend road closure of the A465 between Hirwaun and Cefn Coed starting at 20:00 on Friday, with the road re-opening at 06:00 on Monday.
The weekend road closure is required to undertake work that cannot be safely completed whilst the road is open or under traffic management.
Nant Hir and Baverstock 05/09/22 onwards
From Monday 5 September A465 traffic at these locations will be diverted onto new sections of temporary road.
A new temporary roundabout will also be installed to provide access to the Nant-moel Reservoir.
This will allow the team to begin construction of the new dual carriageway A465 in this location.
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.
