The dualling of A465 Heads of the Valleys road project in South Wales will go ahead after European funding worth almost £82M was granted yesterday.
After securing the funding, the Welsh Government will now give contractor Carillion the go-ahead to begin construction along the Brynmawr to Tredegar section of the A465.
The European Regional Development Fund grant is in addition to a £40M grant from the Welsh Government announced in the 2013-14 budget.
The scheme will include a number of measures aimed at reducing congestion, improving visibility and reducing accidents.
The schemes include realigning 4.7km of the route and upgrading 3.1km of the existing three-lane route to make a dual carriageway, 4km of extra cycle routes and a rest area with extended parking, tourist information and viewpoints towards nearby national parks the Valleys Regional Park and Brecon Beacons.
Carillion will be supported by consultants Arup and TACP who will provide engineering and environmental services.
Construction is due to begin next and due for completion in 2015.
