Four Mile Bridge
Four Mile Bridge (Welsh: Pontrhydybont / Pont-rhydbont / Pontrhypont) is the name given to a bridge and the village surrounding it in Anglesey, Wales. They are so named because the bridge is around four miles by the old road (3 miles "as the crow flies") from Holyhead, the largest town in Anglesey and its surrounding islands. The bridge is one of three connecting the Anglesey mainland to the smaller Holy Island, where Holyhead is located; it was the only land route to Holyhead until the construction of the Stanley Embankment in 1823. It is 120 metres long and carries the B4545 road over the Cymyran Strait.
The village itself is quite small and is split between the two islands, the larger portion being on Holy Island. It is hard to get information on the population of the village as it is split between two communities. It is safe to say, however, that it must be around 500 as the largest part of the village is in the community of Rhoscolyn which has a population of 484, and there is no other settlement of any real size.
