    Legacy Way Tunnel

    4.6-km tunnels in the city of Brisbane. Australia.

    The contract includes the design, construction, operation and maintenance for 10 years of 2 parallel tunnels measuring 12 metres in diameter and approximately 4.6 km long, linking the Centenar Motorway with the Inner City Bypass.

    The tunnels were constructed with two tunnelling machines, measuring 12.40 m in diameter, with a length of 110 m each. During their construction, world speed records were achieved during the excavation with the tunnelling machines through ACCIONA’s continuous innovation at all stages of the project.

    The Legacy Way motorway has been awarded the following prizes:

    • Brisbane Lord Mayor’s Award for Innovation (2012).
    • International Association of Public Participation, Winner in the Infrastructure category (2014).
    • International road Federation, award for Environmental Excellence (2014).
    • Infrastructure Partnerships Australia Project of the year (2015).
