Holyhead Holyhead on the old turnpike. The Stanley Embankment, or "The Cob", is an embankment that connects Anglesey and Holy Island. It carries the North Wales Coast Line railway and the A5 road. The embankment was designed and built by Thomas Telford. When the A5 was being constructed between London and the Port of Holyhead, a more direct route was needed. Construction started in 1822 and completed a year later. It gets its formal name after John Stanley, 1st Baron Stanley of Alderley, a significant local benefactor. In 2001, work was completed on the extension of the A55 North Wales Expressway
