Stanley Embankment

The embankment was designed by, and its construction overseen by, Thomas Telford and was named after the Stanley family who were significant benefactors to the area.

[1] The embankment to Holy Island was constructed using rock and materials excavated from a site on the Anglesey side.

[4] In the 1840s, the embankment was chosen to carry the North Wales Main Line to the Port of Holyhead,rather than build an entirely new crossing.

To allay concerns that passing trains might startle horse drawn traffic using the embankment, a tall stone dividing wall was built between the road and the railway.

The new crossing, which carries the modern A55 dual carriageway, was built parallel to the Stanley Embankment, following its north–south alignment.
