Thomas Telford was a renowned Scottish civil engineer whose Menai Suspension Bridge, completed in 1826, was a pioneering feat of engineering and at the time had the longest span in the world. The bridge significantly advanced suspension bridge technology and connected London to Holyhead, facilitating crucial over-sea travel to Ireland.
