What we’re doing
- building a temporary road
- moving utilities
- building new viaducts at Nant Ffrwd and Taf Fawr
- building a bridge
- junction improvements
We will build a new junction to replace the existing one at the A470/A465 roundabout.
The junction will have two roundabouts on the A470 with roads to the A465.
We are going to build a bridge to carry the A465 over the connector road between the 2 roundabouts.
We will build new viaducts to bridge the Nant Ffrwd and Taf Fawr watercourses.
We will move utilities, including overhead high voltage cables, to build the new road.
Current progress
We have:
- cleared vegetation ready for work to start
- moved the overhead high voltage cables
- built access tracks to the bridges
- completed new farm/property access private road to replace an existing section of private road
- built a new temporary A470 road to the north of the roundabout
- completed the main structure for the new bridge to carry the A465 over the A470
- built piers for the new viaduct to carry the A465 carriageway over Taf Fawr
- started building the carriageway deck for the new sliproad that will go over Taf Fawr. This will allow traffic to come off the A470 and join the A465 eastbound.
