Bridges in this category were constructed with cast iron arch ribs.

In some cases they have been strengthened by the addition of concrete or steelwork. In a small number of cases, original iron castings have only survived as decorative features. The category does not include bridges originally built in wrought iron or steel which have iron castings superimposed for decorative reasons.

Most of the bridges listed are still in existence, but a small number of demolished bridges are included if they were of particular historic significance, or if remnants can still be seen.

In some cases the name of the ironfounder is given in the list below, and the relevant entry will have information about their bridges. In particular, see Horseley Ironworks, who were prolific produces of footbridges for canal companies.
