Victorian engineers were the first to build bridges across wide, deep natural gorges and treacherous waters like the Menai Strait.
Today we build bridges across far greater distances and can see off even greater engineering challenges. Yet the principles remain the same.
So at ICE we are celebrating the very best of bridge building with a major exhibition that spans three centuries of bridge engineering achievements.
A visit to the ICE Bridge Engineering exhibition is free and includes interactive and virtual reality displays, films - and the world's longest ever bridge span made entirely from LEGO.
