CLEM 7 Tunnel

Brisbane, Australia

Client: RiverCity Motorway Pty Ltd

Parsons Brinckerhoff Role: Design

CLEM 7 Tunnel
The Clem Jones Tunnel takes the M7 motorway under the Brisbane River and links five major Brisbane roads. Completed in March, 2010, seven months ahead of schedule, the 3-mile-long (5-kilometer-long) CLEM7 Tunnel is named for Brisbane’s longest-serving Lord Mayor. At a cost of AU$3 billion, it is one of the largest infrastructure projects ever completed in Queensland.

The CLEM7 forms the first part of Brisbane’s new M7 motorway, to be completed in 2012. The new M7 will provide a much-needed motorway link between Brisbane’s northern and southern suburbs, and will improve access to the city’s airport.

The RiverCity Motorway consortium contracted the design and construction of the tunnel to the Leighton Contractors and Baulderstone Bilfinger Berger Joint Venture (LBB JV). Parsons Brinckerhoff, in joint venture, was lead designer to LBB JV.

The CLEM7 Tunnel, which consists of two tunnels with two lanes each, was constructed using hard-rock double-shield tunnel boring machines that were among the largest TBMs ever used in Australia. “Using TBMs of that size presented several challenges in the logistics of setting up, launching and retrieving machines of that scale, as well as providing ventilation for the construction workers and spoil handling as the boring took place,” says Charlie Jewkes, General Manager, Geotechnical, Tunnels and Geospatial, in Parsons Brinckerhoff’s Brisbane office.
