Legacy Way is Australia’s most recent major, urban tunnel project. Legacy Way is a tolled, 4.6km road tunnel that connects Brisbane’s western and inner northern suburbs via the Western Freeway at Toowong and the Inner City Bypass (ICB) at Kelvin Grove. It involves 2 bored twin 12.4m diameter tunnels carrying 2 motorway lanes each; 37 underground cross-passages at 120m interval each with fire life safety protection and management systems; a longitudinal ventilation system; and free-flow electronic tolling. Legacy Way is part of a package of works. It is the fourth of five projects which together form Council’s TransApex ring road, a system of roads, tunnels and bridges designed to reduce inner city congestion and improve cross city connectivity. Transcity, a JV between BMD Construction, Ghella SpA and Acciona Infraestructuras, was awarded the contract for the design and construction of the Brisbane Legacy Way.
Project construction has involved: world record breaking performance for tunnel excavation by two 12.4m diameter double shield Tunnel Boring Machines (TBMs); 38,700 pre-cast concrete segments to line the tunnel walls and over 1,200 concrete piles; underground conveyor tunnel to transport one million cubic metres of spoil to the Mt Coot-tha Quarry; Surface work completed offline reducing construction impacts on motorists; Over 185,000m² of asphalt laid across the whole project; and four hectare expansion of the Brisbane Botanic Gardens, Mt Coot tha.
