Notes

The bridge was originally designed to be a suspension bridge where cables would have supported the tubes and passed through the holes in the pylon tops. The tubes turned out to be stiff enough and the cables were left out. The bridge was considerably damaged by fire in 1970 and has since be rebuilt as an arch bridge, although the original piers remain intact. It now carries the A55 expressway in addition to the main railway line from London to Holyhead ferry port as previously.
