The winter of 1866/1867‚ which was one of the worst

and I decided to construct a simulation of the Sydney Harbor Bridge located in Sydney‚ Australia. Our bridge‚ opened in 1923‚ is a steel arch bridge that is connected at the helm by two towers.

This prevents the bridge from collapsing in on itself and permits the eighteen centimeters of size change during a normal day. On our bridge model‚ we changed the idea of it being held up by these two
