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

Stanley Embankment (The Cob)

Highlight (Segment) • Cycleway

The Embankment crosses the Cymyran Strait, connecting Ynys Cybi (Holy Island) with Ynys Môn (Anglesey). Use the cycle path to get a good view of the tidal water flowing (often, blasting!) through the sluice between the so-called "inland sea" of the Cymyran Strait and the open sea of Beddmanarch Bay.
