A465 Heads of the Valleys Road Improvement Scheme

TMS have recently started to undertake Stage 3 Post Construction Road Safety Audits on the A465 Heads of the Valleys Road at Merthyr Tydfil, Wales. The scheme will see the dualling of Sections 5 and 6 (Dowlais Top to Hirwaun) of the A465 which will improve capacity and journey times through the Valleys, improve overtaking opportunities and improve overall road safety benefits.

To facilitate the dualling, the scheme will also include some major bridge structures and grade separated junctions. It is expected that the scheme will be completed and open in mid-2025.

TMS will be providing Stage 3 Road Safety Audits in the short term for the side road improvement schemes which are necessary to facilitate construction of the mainline.  TMS will then be involved in auditing onto the mainline itself when works are complete.
