The A465 will be changed to 2 lanes in each direction from Glanbaiden junction at Gilwern to Brynmawr roundabout.
For more information about this project, please see Welsh Government links on at the bottom of the page, for information on traffic management see details below.
This work is taking place on an 8km section of the A465 road, between Brynmawr and Gilwern. The existing A465 was built in the 1960s and a traffic study identified the need to improve the road by:
- making the road safer, especially around junctions and areas with poor visibility
- improving traffic flow and making it safer to overtake.
