TBM Grace completes Forrestfield-Airport Link tunnelling journey

18/02/2020


On the 18/02/2020 TBM Grace broke through at Bayswater Station, marking the end of her 8 km journey from Forrestfield to Bayswater after 32 months.

In late July 2017, TBM Grace set off from Forrestfield to Bayswater, building one of two tunnels for the new EUR1.15 bn (AUD1.86 bn) Forrestfield-Airport Link project as part of METRONET.

Half of the 54,000 locally fabricated concrete segments - used to form the walls of the twin tunnels - were installed during Grace's journey, with her route taking her under Perth Airport and the Swan River and through diverse ground conditions.

On the way she passed through Airport Central and Redcliffe Station boxes, large structures in their own right.

TBM Grace will now be dismantled and craned out of the dive structure in preparation for the arrival of TBM Sandy, who is a safe distance behind Grace and is expected to finish tunnelling in May.

Major infrastructure works to build project's three new stations continue

Trains are set to run on the new rail line in the second half of 2021, providing a 20-minute rail link between the eastern foothills, Perth Airport and the Perth central business district.
