Construction of the first of three accoustic sheds in Melbourne city centre signals the start of 24 hours a day, seven days a week tunnelling on the Metro Tunnel.
The 20m high, 70m long shed fully encloses the shaft above the future State Library Station on Franklin Street to reduce the impact of noise and dust from the project.
Two further sheds are planned to enclose shaft sites at A’Beckett Street, which is expected to be completed in mid-2018, and City Square.
“Inside this massive shed excavation is underway to build the new State Library Station,” said Victorian government premier Daniel Andrews. “That’s good news for passengers, and for Victorian workers and industries.”
“We’re building the turn-up-and-go train network Melbourne needs – where trains come so often you can throw away the timetable.”
The new tunnel will untangle the City Loop and create space for more trains to and from the city’s suburbs. The project involves driving 9km of new twin bore tunnel and construction of five new stations.
