Balfour Beatty and Dawnus Construction have each signed early contractor involvement (ECI) deals worth over £90M with the Welsh Government to carry out major road construction works.
Balfour Beatty will build the 9.8km A487 Caernarfon to Bontnewydd Bypass in North Wales after beating competition from four other contractors with a bid of £65.5M. Under the contract Balfour Beatty will provide design, environmental and construction services.
The bypass will start at the A499/A487 Goat roundabout and end at the existing A487 Plas Menai roundabout. The route will form a western bypass to Llanwnda, Dinas and Bontnewydd before crossing the existing A487 to pass south of Caernarfon Quarry. It will then cross the River Seiont, passing south of the Cibyn Industrial Estate to a junction with the A4086. Finally, the route will cross the B4386 before connecting with the Plas Menai Roundabout.
Work is expected to start on site in late 2016 with the project to include 18 structures. Seven of these will be bridges, including a 280m bridge over the River Gwyrfai and a 300m bridge over the River Seiont.
Dawnus Construction has won an ECI contract to build the Eastern Bay Link road in Cardiff, beating off four other contractors with a bid of £27.3M.
The project – between Queens Gate Roundabout and Ocean Way Roundabout in the capital – will involve construction of a dual carriageway to improve access to Cardiff Bay and the Cardiff Central Enterprise Zone. It will require construction of a high skew bridge to accommodate the current layout of an existing dockland access road, two level crossings and a railway line to the neighbouring Celsa site.
