WORK to install bridge beams as part of a project to build two viaducts as part of the Caernarfon and Bontnewydd bypass has now been completed. Balfour Beatty Jones Bros Joint Venture is delivering the £135m bypass which is one of the largest infrastructure projects underway in North Wales. The 9.8km bypass will run from the Goat roundabout on the A499-A487 junction to the Plas Menai roundabout around Llanwnda, Dinas, Bontnewydd and Caernarfon. The scheme will deliver improved travel times, reduce congestion and improve air quality on local roads, and lead to more opportunities for active travel. Another key milestone has been reached as surfacing work is now beginning on the bypass near the Cibyn Industrial Estate in Caernarfon.
