A4080 road

The A4080 is a British A road which is located on the Island of Anglesey, Wales. It follows a very roundabout route from the A5 road at Llanfairpwllgwyngyll via Newborough and Rhosneigr back to the A55 and the A5 about 9 miles south of Holyhead. In all the road is about 17 miles long.
The A4080 branches off the A5 at Llanfairpwllgwyngyll, bridges the main railway line and heads south. At first it runs parallel with the Menai Strait but then moves further inland passing through the village of Brynsiencyn, where there are some sharp bends, and curving round the village of Dwyran. Another sharp bends leads to a straight section of road which passes the Anglesey Model Village. This section ends in a roundabout from which the last exit turns northwestwards and soon reaches Newborough where the B4221 branches off to the right. Passing through Newborough Forest and past Malltraeth Sands, the A4080 crosses the Afon Cefni at Malltraeth.
