On Thursday 21 April 2016, Deputy Project Director and ICE Member, Ian Stuart led a group of civil engineers and civil engineering university students on a short tour of the Sydney Metro Northwest skytrain construction project.

Together with Australia's longest railway tunnels, the 4km long skytrain viaduct - now under construction by Salini-Impregilo, comprises Sydney Metro Northwest.

The $8.3 billion infrastructure investment includes eight new metro stations, 4000 commuter car parking spaces and a train every four minutes during peak times.

As well as the 4km of 9m high viaduct between Bella Vista and Rouse Hill with its 112 piers and spans of 39m, the contract includes Australia's first cable stayed railway bridge which will be built on a curve. The 270 metre long bridge will be supported by 32 cables and two towers up to 45 metres high.

The bridge consists of 84 individual concrete segments lifted using a 700 tonne launching gantry. It will be constructed on a continuous '24/7' programme.

After an introductory presentation and health and safety induction at the project site office, the group visited two major sites, at Kellyville Station and the cable stayed bridge.
