The work will provide a permanent solution on this stretch of road which has had traffic management in place since an emergency closure in October 2023, when a retaining wall which supported the road partially collapsed.
Detailed design work on the permanent solution is now complete and work can begin.
It will improve the resilience of the A470 and ensure a similar emergency closure, and the disruption that brings, is less likely to happen.
The works to repair the retaining wall above the adjacent Afon Laen will mean the stretch of road will be closed 24hrs per day throughout this period, however roads engineers are working to reduce the duration of the work as far as possible.
Following this closure period, 2-way traffic lights will be reinstalled at the site to complete construction activities.
All traffic management will be removed from the site by 14 February 2025.
The work is taking place during a quieter period on the road, including the half term holiday.
This work is essential in order to ensure the road can remain open in the years to come.
We understand this will cause disruption in the short term while the work is under way, and we thank drivers for their patience. It is vital this work is carried out at this time for the future resilience of the road.
Further details of the roadworks and diversion route are available on the Traffic Wales website.
