International firms are gearing up to start phase two of Sydney’s new metro system, which includes the recent completion of Australia’s longest tunnels. At $15 billion, the 66-kilometer-long metro represents the country’s largest transportation investment so far.
Trains are due to start running on the 36-km north-west phase, between Rouse Hill down to Chatswood, in about two years. The $6.2-billion line includes 15 km of twin tunnels and the country’s longest bridge, the 4-km Skytrain viaduct.
