• A cable-stayed bridge, one of the most modern bridges, consists of a continuous
strong beam (girder) with one or more pillars or towers in the middle.
• Cables stretch diagonally between these pillars or towers and the beam
– These cables support the beam
• The cables are anchored in the tower rather than at the end
