The Bridge
Thomas Telford designed and built all types of infrastructure; from churches to castles, canals to harbours, tunnels to roads and bridges. The Menai Bridge was probably Telford’s most acclaimed achievement. It was the first iron suspension bridge of its kind in the world and it established the potential of suspension bridge technology to achieve both long and high spans. Telford designed the central span of the roadway, 176m long and 30m above water level, to be carried by 16 wrought-iron chains, each made of 935 iron bars (since replaced by steel chains).
The bridge was a massive improvement in communication, not only for the people travelling to Ireland via Holyhead, but also for the locals. For the first time, they could cross with their livestock to and from the mainland without fear of perishing in the fast-flowing, dangerous waters of the Menai Strait.
