A £139 million Gwynedd bypass is set to open to the public later this week.

The Welsh Government has confirmed this afternoon that the 9.8km A487 Caernarfon and Bontnewydd bypass, which has cost £139 million, will open to traffic on Friday.

Work on the project started in June 2019 and continued throughout the pandemic

The announcement was made on Twitter on the Welsh Government Transport’s official page saying: “The Welsh Government has confirmed this afternoon that the A487 Caernarfon and Bontnewydd bypass will open to traffic on Friday morning, 18 February.

“The road has been completed ahead of time, with work continuing safely throughout the pandemic.”

The new bypass aims to make it easier to travel between Llyn Peninsula, Porthmadog, Bangor and the A55, reduce noise and air pollution for people who live along the A487, make it safer for people to travel between towns, make it easier for heavy goods vehicles to travel in the area and make it safer to travel between Caernarfon, Bontnewydd by walking and cycling.

The bypass will run from the Goat roundabout at the A499/A487 junction in Dinas towards the Plas Menai roundabout in Y Felinheli.
