Westgate Tunnel Project Also Has Bridges
As most Melbournian’s would know, the Westgate Tunnel Project is not all underground. There are massive on-ramps, off-ramps, bridges and overpasses that start at the West Gate freeway, run through Yarraville, and wrap up in West Melbourne. Have you ever wondered how these massive pieces of bridge are placed into position with such precision? Well, Flotek played a part – read on.
Purpose:
The Westgate Tunnel Project aims to provide a crucial alternative to the Westgate Bridge. We know that on the Westgate freeway, a single incident can bring traffic to a stand-still. This new alternative route will create better connections between the west and the city, reducing traffic congestion and travel times on what is Melbourne’s busiest freeway. Not to mention taking thousands of trucks off residential streets.
Cost:
The project has a total estimated cost of around AUD 11 billion, making it one of the largest infrastructure projects in Victoria.
Tunnel Length:
The main tunnel of the project spans approximately 9 kilometres, including 5 kilometres of twin tunnels.
Construction Challenges:
Building the tunnel required overcoming significant challenges, including working under existing road infrastructure.
Engineering Feat:
The tunnel boring machines (TBMs) used in the project are among the largest ever used in Australia, with diametres of about 15.6 metres.
Bridges and Overpasses
Enerpac and Flotek were engaged by WTP to help manage and place the bridges and overpasses in the project. Flotek provided approximately 400 Enerpac jacks, 30 pump units, and a series of Enerpac hydraulic synchronised hoists to help lift and position the massive bridge girders. Check out the photos below.
The hydraulic synchronised hoists are the best solution when you’re dealing with such massive weights. This work was carried out mostly around Footscray Rd and Whitehall St with Flotek staff on hand to assist with the operation of the jacks and synchronised hoists.
Community Benefits:
The project has created thousands of jobs during construction and provides long-term economic benefits by improving transportation efficiency.
The project also introduced new walking and cycling paths, as well as open space in Melbourne’s west, making it an even better place to live, work, and play.
Completion Timeline:
The project is scheduled for completion in 2025, with various stages of construction already finished.
Integration with Other Infrastructure:
The Westgate Tunnel will connect to other major roads and infrastructure, including the CityLink freeway, enhancing Melbourne’s overall transport network.
