What we're doing

  • moving utilities
  • building a bridge over the Afon Cynon and Vale of Neath railway line
  • building an underpass at Court Farm
  • building a new bridge over the A465 at Pentwyn Cynon
  • laying new road

We will build new structures to allow the A465 to pass over the Afon Cynon, Court Farm access and Vale of Neath railway.

The structures and road will be built in two halves starting with the westbound section of road.

When all traffic is moved onto the westbound section of road, we will build the eastbound structures and road.

Pentwyn Cynon bridge will be built over the new road for Non-Motorised Users (NMUs).

  • cleared the site and vegetation
  • stripped topsoil between Court Farm and Vale of Neath

  • summer 2022 to autumn 2022: we will build the Court Farm underpass
  • summer 2022 to autumn 2022: we will build the Vale of Neath bridge
  • 2022: we will build the embankment, install drainage barriers, fencing and lighting, and laying the surface of the new road.
