The Sydney Metro – Western Sydney Airport project has reached new heights with the completion of the 3.2-kilometres of bridge linking the Warragamba viaduct to the future Luddenham Station.
The new 23-kilometre metro line will mean it’ll take passengers five minutes to travel from the airport to Bradfield, approximately 15 minutes from the airport to St Marys and approximately 20 minutes from Bradfield to St Marys where passengers can connect to the rest of Sydney’s rail network.
The impressive viaduct structure is a critical part of the metro alignment between Orchard Hills and Luddenham and has been constructed to take metro services over key locations including the Warragamba pipelines, Blaxland Creek, and Luddenham Road.
This viaduct will be part of a mix of underground tunnels, ground level railway and elevated railway.
“This project will also deliver major economic stimulus for Western Sydney, supporting more than 14,000 jobs,” Premier Chris Minns said.
“There’s more to do, but it’s great to see the progress being made on this world class infrastructure project, which will benefit our great city for generations to come.”
A total of 1,101 precast concrete segments were used to construct the viaduct, with each segment measuring 10.85 metres wide, up to 3.2 metres long and 2.4 metres high, and weighs up to 65 tonnes, with more than 52,000 tonnes of concrete used to cast the segments.
Supporting the impressive structure are 84 piers, each weighing between 80 and 160 tonnes and towering up to 15.3 metres high. The piers were made using 96,250 tonnes of concrete.
To build the viaduct, more than 2,500 people worked over 16 months with huge machinery to manoeuvre the heavy segments.
“With huge milestones ticked off both below and above ground, we can now start to prepare for tracklaying,” Transport Minister Jo Haylen said.
“This above-ground megastructure is a true engineering feat, built safely and with precision to ensure passengers have fast and reliable journeys in Sydney’s Greater West.
“As we reach this important stage, we are closer than ever to delivering a modern, reliable, and efficient metro system that will drive growth and support the region’s long-term development.
“Once open, Western Sydney Airport line will service the new international airport and connect communities between St Marys and Bradfield to wider Sydney, with the capacity to carry 7,740 passengers an hour in each direction on their new metro service.”
