ATS QLD – M4-M5 Link Tunnels Project Update
April 8, 2020 @ 5:30 pm - 7:00 pm AEST
The M4-M5 Link Tunnels project is the final and most critical component of WestConnex, featuring twin tunnels between the New M4 at Haberfield and the New M5 at St Peters. Each tunnel will be approximately 7.5 kilometres long and will be able to accommodate up to four lanes of traffic in each direction.
This results in the excavation of tunnels of unprecedented size in Australia, with main line tunnel spans up to 23m in width and Y-junction caverns up to 34m.
A demanding construction programme adds to this scale complexity and to meet these challenges, the project will have up to 27 roadheaders operating from three different construction sites at its peak construction.
Our speakers will present the current progress of the project and some of the challenges associated with both the design and construction of these tunnels as well as some of the innovations adopted with respect to spaceproofing, ground support and planning.
