Some great views here and it mostly gets you out of the prevailing SE wind. Watch out for tractors driven by 16 year old Lewis Hamilton wannabes! Get the tide right and you can ride along the beach at Dulas.

The bridge itself takes the same name as the village it is situated in and is one of three bridges connecting Holy Island and Anglesey. The bridge is approximately four miles (6.5 km) from Holyhead via the old road route, giving it, and the village, its name. A bridge at this location was in existence by 1530, and was the only land route to Holyhead until the construction of the Stanley Embankment in 1823. It is 120 metres (390 ft) long and carries the B4545 road over the Cymyran strait. I think the crossing over the water is about 5km

It’s definitely not 4 miles long, but it is 4 miles from Holyhead (on the old road). Until the 1800s this was the only crossing to Holy Island; now it forms the ‘inland sea’ together with the main crossing on The Cob embankment at the northern end of the Cymran Strait.
