Construction of AirportlinkM7 commenced in November 2008 and
involved a number of significant aspects including;
- two tunnel boring machines (TBMs) at 12.48 metres in
diameter and 195 metres long, almost the length of the MCG
- 17 roadheaders
- 125,000 tonnes of reinforced steel
- 807,000m3 of concrete
- at it's peak, the project employed 4,500 people
The TBMs were custom made for the project and were the largest
to ever operate in Australia.
AirportlinkM7 was constructed in conjunction with the Northern
Busway (Windsor to Kedron) and Airport Roundabout Upgrade, both of
which were handed over to the State Government for operation.
Design and construction of this integrated transport solution,
within the densely populated environment of inner-city Brisbane and
the northern suburbs, represented one of the most challenging
engineering feats in Queensland's history and included 25
bridges, 15 kilometres of tunnelling and over
7kilometres of new road.
