Built between 1819 and 1826, the Menai Bridge was the major structure on Britain's strategically important Holyhead Road connecting London with Holyhead and by sea to Ireland. Designed by Thomas Telford, the bridge's main span was 579 feet from tower to tower, the longest that had ever been attempted at this time. He used four sets wrought-iron eyebars to suspend the deck. These were made by William Hazledine at his Upton forge near Shrewsbury. Each bar was carefully tested in his Coleham shops before being pinned together and lifted into place.
Telford, Thomas

Traversing the Great Glen of the Scottish Highlands for 60 miles the Caledonian Canal connects the North Sea by Beauly and Moray Firth on the east coast with the Irish Sea by Lochs Linnhe and Eil on the west. Thirty eight miles of the canal pass through freshwater lochs Douchfour, Ness, Oich and Lochy with the remaining 22 miles formed by earth cutting. Initially 28 locks, and later 29, were required to reach the summit elevation of 106 feet at Loch Oich.

The Gota Canal is the biggest infrastructure project ever built in Sweden. The canal was dug by hand with shovels made of wood. It took over 22 years of 12-hour days - an estimated 12 million man-days of labor - to complete the project.

This elegant cast iron arch bridge designed by Scotland's famous Thomas Telford was built from 1812 to 1814. It is the earliest surviving example of a portable lattice-braced standard type that Telford developed for use at wide and deep water crossing sites unsuitable for masonry spans. At least 10 of these bridge types were erected throughout Britain between 1814 and 1829.

When a new road bridge was constructed alongside it, plans were made to demolish the Conwy Suspension Bridge. There was a national outcry and, since 1958, the bridge has been in the care of the National Trust and closed to vehicular traffic.
