Con­struc­tion starts this year on new Syd­ney Metro tun­nels

“The scale of this project will ri­val any megapro­ject across the globe”

Con­struc­tion starts this year on new Syd­ney Metro tun­nels which will run un­der Syd­ney Har­bour and the CBD, with the green light now given for the project to pro­ceed.

New South Wales (NSW) Min­is­ter for Trans­port and In­fra­struc­ture An­drew Con­stance wel­comed plan­ning ap­proval for the sec­ond stage of Syd­ney Metro, which starts at Chatswood and trav­els be­neath Syd­ney Har­bour, through the CBD to Sy­den­ham and on to Bankstown.

The ap­proval is for the Chatswood to Sy­den­ham sec­tion of the project.

“The scale of this project will ri­val any megapro­ject across the globe, and to­day marks the start of even more grunt work,” Con­stance says.

“This is an un­prece­dented boost to rail ca­pac­ity for our great city.”

Con­struc­tion sites will be es­tab­lished in Syd­ney’s CBD this year.

By the end of 2018, the first of five tun­nel bor­ing ma­chines will be in the ground carv­ing out new twin tun­nels.

Syd­ney Metro will have ul­ti­mate ca­pac­ity of a new metro train ev­ery two min­utes in each di­rec­tion un­der the Syd­ney CBD and 31 metro sta­tions from Rouse Hill to Bankstown – a 66km new rail­way for to­mor­row’s Syd­ney.

NSW Plan­ning Min­is­ter Rob Stokes says the go-ahead for the project en­sured Syd­ney is be­ing pre­pared for the fu­ture.

“This project has been ap­proved and sub­jected to some of the high­est sus­tain­abil­ity pro­vi­sions in the world.”

Among the con­di­tions im­posed with the ap­proval is that green­house emis­sions by elec­tric­ity con­sumed by the op­er­a­tion must be fully off­set.

Two con­sor­tia are com­pet­ing to build the new twin tun­nels, with the con­tract ex­pected to be awarded around the mid­dle of this year.

More than 300 sub­mis­sions were re­ceived dur­ing six weeks of pub­lic con­sul­ta­tion last year on the en­vi­ron­men­tal im­pact state­ment for the Chatswood to Sy­den­ham sec­tion.

Pub­lic feed­back has helped re­fine the de­liv­ery of Syd­ney Metro, with lo­cal in­put driv­ing changes that in­clude us­ing barges on Syd­ney Har­bour to move tun­nel­bor­ing ma­chine parts from the north of the har­bour, and to take crushed rock from the Baranga­roo Sta­tion site, re­duc­ing im­pacts on roads and traf­fic.

A fu­ture un­der­ground pedes­trian link from Martin Place Sta­tion to O’Con­nell Street will be safe­guarded, fur­ther im­prov­ing pedes­trian ac­cess, and any rock-break­ing work that uses heavy con­struc­tion equip­ment will only take place dur­ing stan­dard con­struc­tion hours – with the ex­cep­tion of Cen­tral Sta­tion. This will sig­nif­i­cantly re­duce po­ten­tial noise im­pacts for the com­mu­nity.

The plan­ning process for the con­ver­sion and up­grade of the Bankstown line to Metro stan­dards will start this year.
