It is proposing to upgrade 18 km of the A465 trunk road between Hirwaun and Dowlais Top under a design, construct, operate and maintain non-profit distribution contract model.
If the A465 dualling is given the final go-ahead by the Welsh Government next year, it would take three years to construct, commencing in late 2019 with completion in 2022.
This is the final section of a 40 km improvement to the A465, spanning from Hirwaun in the west to Abergavenny in the East.
The Welsh Government has appointed engineering consultant Jacobs to develop the design, produce an environmental impact assessment and take the scheme through the statutory process and seek the powers to build the road.
Dowlais and Hirwaun project
The A465 will be upgraded from 3-lane single carriageway to dual 2-lane carriageway. This includes 2.2 km off-line new road construction from Hirwaun to Trewaun and six full movement grade-separated junctions located at Hirwaun, Croesbychan, Baverstock, A470, Prince Charles Hospital, and Dowlais.
The successful consortium will deliver over 100 structures, including four large viaducts, 35 widened or constructed bridges and retaining walls and culverts.
The operation and maintenance network will comprise the new A465 trunk road between Dowlais and Hirwaun although inclusion of the operation and maintenance of the A465 trunk road between Abergavenny and Dowlais is also being considered.
Details of the exercise including how economic operators can participate and relevant deadlines will be set out in the market engagement briefing.
