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. 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. 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. There are two ventilation shafts. The western shaft is located in the Brisbane Botanic Gardens, Mount Coot-tha with the station underground. The eastern shaft is located near the ICB, Kelvin Grove, and will partially be built into an existing hill. 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. Joyce TBM concluded the boring of the eastbound tunnel on 24 April 2013, taking 7 months to reach breakthrough. Annabell TBM concluded boring of the westbound tunnel at 10:47 am on 13 June 2013, taking 10 months to reach breakthrough. Both TBMs bored in the same direction.

An 870 m long conveyor tunnel transports excavated material from the western tunnel entrance to the quarry.
