The Melbourne Metro Tunnel is one of the largest public transport projects undertaken in Australia.

The Melbourne Metro Tunnel consists of five new stations and twin nine-kilometre cross-city railway tunnels connecting the south-eastern and north-western suburbs. Boral is supplying construction materials for the manufacture of 56,000 precast concrete segments to line the project's twin nine-kilometre tunnels. Boral’s innovation and technical teams from across the country have been developing solutions for the technically complex elements of this project. 

Boral's highly specified concrete is being supplied to meet the project's stringent fire resistance requirements via a purpose-built mobile batch plant at our Deer Park site in western Melbourne.

This project is expected to increase the capacity of the Melbourne railway network by an additional 39,000 passengers during each peak travelling period per day. It is expected to be finished by 2025.
