It should be noted that the materials to be implemented in our bridge design would be steel for the piers, pre-cast reinforced concrete elements for the bridge and steel tension cables connecting the piers to the bridge (see pictures of Day 4).
It is well known that steel is a material that performs especially well in tension therefore the decision to use that as tension cables. The thinking behind the use of concrete for our walkway, was that the bridge would be under a heavy traffic flow, as many University students will be using this bridge as a safer way to traverse either side of Lewes road to connect the Moulscoomb campus of the University of Brighton. With such heavy demand, it was decided a dense and solid material for our bridge was needed and reinforced concrete became our material of choice.
