Preferred bidders for the Rail Infrastructure Alliance
The $1 billion Rail Infrastructure Alliance (RIA) works package, is the last major contract as part of the Metro Tunnel project.
The RIA works package also includes works on train lines out in the suburbs to maximise the benefits of the Metro Tunnel and take full advantage of the extra capacity it creates.
Public spaces near the eastern tunnel portal, including South Yarra Siding Reserve, Lovers Walk and Osborne Street Reserve, will be rejuvenated as part of these works before being returned to the local community once tunnel entrance works are complete.
Around 1000 people will work on the RIA package. Site preparations ahead of portal construction will commence later this year, with most RIA works expected to be finished in line with the completion of the tunnels and stations, by the end of 2025.
