AUSTRALIA: MELBOURNE ROAD TUNNEL Major tunnelling works have been in preparation for the North East Link in Melbourne, one of the longest road tunnels in Victoria, Australia. The tunnels will be bored by two 15.6m-diameter


Herrenknecht TBMs, driving from Watsonia south towards Bulleen. Last year a sight for locals was the cutterheads being lowered into place at the launch for the TBMs are among the biggest used in the southern hemisphere. Fully assembled, the machines are 90m long and


weigh more than 4,000 tonnes. They will install 44,000 segments along the 6.5km-long twin tube tunnels, driving up to 45m below ground. The TBMs are designed to advance at approximately 10m per day Tunnelling is scheduled to be completed in 2026 for


the road link to be open to traffic in 2028. The twin tube, three-lane tunnels will connect the M80 Ring Road to the Eastern Freeway.
