The first one is http://en.wikipedia.org/wiki/Brooklyn_Bridge, this site has gelped me gather information on The Brooklyn Bridge which is the bridge I am researching on for my chosen bridge.

The second one is http://www.howstuffworks.com , this site has helped me reasearch and teach me how to build a suspension bridge which i am building. It has also has information suspension bridges and many other bridges.

People involved

Bridges are usually designed by engineers who draw up all the plans along with an architect. When it is time build it they will start both ends and work ther way across until it meets.
