CLEM7 Tunnel

Project Overview

The CLEM7 Tunnel is part of Brisbane’s Transport Plan, and the first critical component of the Lord Mayors TransApex vision that aims to reduce deficiencies in Brisbane’s urban road network.

The CLEM7 links five existing major motorways and arterial roads on the north and south sides of the Brisbane River. The 6.8 kilometre tollway includes twin, 2–lane 4.8 kilometre tunnels.

The Project also includes a state of the art fully electronic tolling system and unique urban design and landscaping concepts that complement the subtropical lifestyle and liveability of Brisbane.


Construction commenced in 2006 shortly after Financial Close, with the LBBJV targeting an aggressive completion date. The tunnel was opened in March 2010, some 7 months earlier than the contracted date. The early completion target was facilitated by early design works that commenced shortly after announcement of RCM as the preferred bidder, which enabled the early ordering of the tunnel boring machines.

Operations and Maintenance

Brisbane Motorway Services (a Leighton Contractors/Lend Lease Joint Venture) is the Operations and Maintenance (O&M) contractor for the CLEM7. Their obligations are to operate, maintain and repair all civil, structural, mechanical, electrical and roadside tolling services for the Clem Jones Tunnel until the handover at the end of the Concession Period.  Leighton Contractors holds a 50% stake in BMS.


The CLEM7 is one of Australia’s safest tunnels. A range of safety features and systems operate in the tunnel to provide the safest driving environment possible.

  • Traffic Management
  • Cross-passages
  • Fire and Safety Equipment

Safety is our number one priority. We provide a safe and fulfilling work environment for our people. Our Safety Essentials program is our commitment to safety, our minimum and non-negotiable requirements that must be met to help keep our people and workplaces safe. Our team continually reviews world best practice in safety procedures and equipment to increase safety of staff and the community.


Toll collection for the CLEM7 is managed by FLOW tolling, Brisbane’s newest and most economical toll provider. Tolls are collected through a fully electronic tolling system that identifies motorists using the tunnel via an electronic tag fitted inside their vehicle or by taking a photograph of their number plate.

CLEM7 is the first section of the new M7 motorway in Brisbane. The M7 is due to be completed in 2012 following the construction of the 6.7km Airport Link tunnel, which will provide a direct connection from the CLEM7 to the Airport and the growing northern suburbs.
