The M5 Legacy Way (formerly Northern Link Tunnel) is the fourth of five components of Brisbane City Council's TransApex Project. The project involves two bored tunnels carrying two motorway grade lanes of traffic in each direction from the Western Freeway in Toowong to the Inner City Bypass at Kelvin Grove. The tunnels will be tolled for approximately 45 years[1][2] and will be approximately 4.6 kilometres (2.9 mi) long.[3]

The Environmental Impact Statement was released for public comment in September 2008 and approved in April 2010. Construction commenced in April 2011 with plans to open the tunnel to traffic in late 2014. It is expected to carry 34,200 vehicles a day when it opens and reduce travel time between the Centenary Bridge and the Inner City Bypass by 70%.[2]

The project will be funded through council borrowings, together with a state and federal government contribution.

Tender process[edit]

Three consortia were shortlisted and invited to submit proposals in December 2009:[4]

The tenders for the design, construction, operation and maintenance of the tunnels for up to 20 years[5] were submitted on 12 May 2010,[6] however on 5 July the BCC announced that the Leightons Baulderstone Razel joint venture bid would not be considered.

On 20 September 2010, Lord Mayor Campbell Newman announced that the winner of the tender process was Transcity.[7] The project is being delivered by Transcity, a joint venture between Brisbane-based BMD Constructions,[8] Italian tunnelling specialists Ghella,[9] and Acciona Infrastructure, a Spanish civil engineering, construction and infrastructure conglomerate. Acciona Infrastructure is the lead partner of the Transcity Joint Venture who are responsible for the design, construction, operate and 10 year maintenance.[10]

Name change[edit]

In November 2010 the Brisbane City Council has revealed that the Northern Link will be named Legacy Way in honour of the men and women serving in the Australian Defence Force. One cent of every toll (equating to $5.5 million over the lifetime of the road) will go to Legacy Australia, an Australian volunteer organisation caring for the families of deceased and incapacitated veterans, including the families of fallen Australian Defence Force personnel.[11][12]

Tunnel design[edit]


Legacy Way will comprise two 4.6 km (2.9 mi) long parallel tunnels that will pass underneath Toowong, Auchenflower, Milton, Paddington, Red Hill and Kelvin Grove. Some design features include 36 underground cross passages, spaced every 120 m, a longitudinal ventilation system, fire protection and safety management systems and free-flow tolling.[13]


In April 2012 Brisbane City Council Lord Mayor Graham Quirk was quoted as stating that the former Labor state government had failed to support during the design phase of the project a busway connection linking Legacy Way's eastern end with the Northern Busway. Despite a change in state government, the minister responsible for the Department of Transport and Main Roads, Scott Emerson, could not justify a busway connection at a cost of AUD 30 million. Although the inclusion of a busway connection represented only 0.25% of the project's overall cost, the LNP state government were at the time focused on reducing the Queensland government debt.[14]

In November 2013 The Queensland Minister for Transport and Main Roads announced a plan to connect buses from the Underground Bus and Train Tunnel project with Legacy Way.[15]

In April 2014 Queensland Premier Campbell Newman confirmed a plan to shorten the travel time of Brisbane Transport's western suburbs bus routes by connecting Legacy Way with the Bus and Train (BaT) Tunnel project. By 2020 re-routed bus services will save 15 minutes per journey. Design options involving ramps or bridges linking both tunnels were being considered.[16]

Ventilation shaft[edit]

There will be two ventilation shafts. The western shaft will be located in the Brisbane Botanic Gardens, Mount Coot-tha with the station underground. The eastern shaft will be located near the ICB, Kelvin Grove, and will partially be built into an existing hill.[17]



The initial financial assessment of the impact of the Brisbane River catchment flood in January 2011 threatened to suspend the Legacy Way project. If the project was suspended for six months, as outlined in Section 11.9 of the Legacy Way project deed, Brisbane City Council would have been required to compensate the Transcity consortium AUD220 million.[18] Brisbane City Council confirmed the flood would not delay the project.[19]

Boring was expected to commence in June 2012 but was delayed due to changes in legislation relating to tunnelling. Transcity is contracted to close the project by end of February 2015. For every day the project is late, a penalty of AUD250,000 is incurred. Transcity were reportedly negotiating with Brisbane City Council a date extension to close the project by.[20][21]

Tunnel boring[edit]

Two Herrenknecht Double Shield tunnel boring machines (TBMs) bored from the Mt Coot-Tha roundabout, Toowong, toward the Inner City Bypass (ICB), Kelvin Grove. The TBMs were named Annabell and Joyce, as a tribute to Legacy Australia. Annabell is named after Annabell MacKinney, the daughter of the late Lance Corporal Jared MacKinney who was killed in action in the war in Afghanistan in 2010. Joyce is named after Joyce Tweddell, a nurse during World War II who showed immense courage after being held as a prisoner of war in Sumatra for 3 years before returning home and going on to become Queensland's chief radiographer at the Royal Brisbane and Women's Hospital.[22]


Joyce TBM concluded the boring of the eastbound tunnel on the 24th of April, 2013, taking 7 months to reach breakthrough.[23] Annabell TBM concluded boring of the westbound tunnel at 10:47am on the 13th of June, 2013, taking 10 months to reach breakthrough.[24] Both TBMs bored in the same direction.

Spoil created from the excavation earthworks is being deposited at the Mount Coot-tha Quarry. An 870 m long conveyor tunnel transports excavated material from the western tunnel entrance to the quarry.[25][26]

Tunnel operator[edit]

On 16 July 2013 it was reported that Queensland Motorways Holding Pty Ltd (QMH) had acquired a 50 year lease to toll, operate and maintain Legacy Way from Brisbane City Council. The following July, Queensland Motorways was acquired by a Transurban consortium, which will manage and operate the tunnel upon its opening.

The majority of the toll revenue will go to Transurban with Brisbane City Council expecting to receive between $1.08 billion and $1.58 billion by 2020.[27]

On 18 September 2013 an informal review conducted by the ACCC concluded that the acquisition would not result in a substantial lessening of competition in any of the relevant markets.[28]

Toll price[edit]

On 10 April 2014 it was reported that the toll for Legacy Way will be announced in 2015 and will be set by Queensland Motorways. The Lord Mayor of Brisbane, Graham Quirk, speculated that the toll will be about $5.00 each way for cars. The Queensland government's Department of Transport and Main Roads confirmed that a $5 toll was last approved by the Department in 2011 and is adjusted to the CPI at the start of each fiscal year commencing 1 July.[29]
