Annabel will excavate the westbound tunnel. Tunnelling was expected to begin in June 2012, but ran behind schedule due to changes in legislation regarding tunnelling, the company stated. Transcity incurred a AUS 250,000 (USD 259,400) penalty each day it ran late.
The second TBM, Joyce, which is being assembled on site, will start excavation of the eastbound tunnel later this year. It will take approximately 18 months for the TBMs to complete the journey from the western worksite at Toowong to the eastern worksite at Kelvin Grove.
The company is currently in negotiations with council to extend that date.
Legacy Way is a 4.6 km road tunnel that will connect the Western Freeway at Toowong with the Inner City Bypass at Kelvin Grove. Once open in 2015, Legacy Way will reduce peak hour travel times between the Centenary Bridge and the Inner City Bypass by 44 per cent.
