Metro Tunnel

Expression of interest

The Rail Infrastructure Alliance (RIA) will include works at the eastern and western tunnel entrances and exits (portals) including cut and cover tunneling, decline structures and the reconfiguration and realignment of existing lines to connect the new Metro Tunnel rail tracks to the existing surface network. RIA will also deliver associated tunnel, track and signalling works along the Sunbury and Dandenong lines to support the reconfiguration of the rail network to support day one operations of the Metro Tunnel.

An expression of interest for the RIA contract has been released and will close in mid-September 2017. The contract is expected to be awarded in the second half of 2018. The capital value for the RIA package is around $1 billion.
