      I think that the situation where the bridge will be placed will have been studied so that things like high winds, or fast flowing water will have been measured and understood so that the bridge design can be made with stronger parts where needed, or using materials which won’t be damaged by the environmental conditions.

      I imagine Roma will be able to give us a good answer on this one though!

      Cathy’s right- we do maths, physics, and make computer models to see how a bridge works in the wind and water, and make sure the steel and concrete is strong enough for all those things.

      Roma’s got this one covered I think!

      I’d like to be back in the Victorian times to see how they managed to build bridges without the use of calculators and computers!

      Hi,
      There are loads of cool pictures of a new bridge begin built near Edinburgh here: http://www.forth-bridges.co.uk/queensferry-crossing.html

      I love begin able to watch the progress as I take the train north. For a while there was a huge hole in the water. It looked very strange!
