 * Suspension Bridge **** of Menai **


 * Today's biggest suspènsion bridge was built using ancient technology **

They wanted to solve the connection between London (England) and Dublin (Ireland) Menai strait at Wales was an obstacle for people travelling to Ireland in the 19th Century The designer was Thomas Telford, a 36 years old Civil engineer which had a very good reputation in Britain. He was give that huge job to improve main couching route between Britain and Ireland. In the video there’s no info about the date in which it was built. And it was constructed in Britain Telford first wanted to construct an arch bridge but he would have to use scaffolding to support the arch while building. And that would block the movement of ships and planners don’t accept it. Then he went back to basics to the rope bridges, considering the suspension principles. But then, another point to consider arises, securing the chains at each end. They secure the chains deep into a rock, caving an 80m long tunnel. At the end of the tunnel they position strong iron frames and secured it using bars of metal.
