1 CLEM JONES TUNNEL PROJECT UPDATE AUGUST 2008 Two kilometres of tunnel has been excavated at Kangaroo Point and tunnel lining work is now under way. BETTER TIMES AHEAD ON CLEM7 Fast facts Road length 6.8 kilometres Tunnel length 4.8 kilometre twin, 2-lane tunnels Rock to be excavated 3.5 million tonnes Tunnel lining segments 38,000 Concrete to construct tunnel 280,000 cubic metres Brisbane motorists can look forward to better times ahead with progress continuing ahead of schedule on Brisbane s first major road tunnel the Clem Jones Tunnel (CLEM7). The project s two massive tunnel boring machines have each advanced more than 1.2 kilometres and are currently digging 50 metres below Brisbane s Fortitude Valley. Tunnelling four kilometres from Bowen Hills to Woolloongabba, Matilda and Florence remain on track to be under the Brisbane River by September Smaller roadheader tunnelling machines working at Kangaroo Point and Woolloongabba have now completed more than 70% of their rock excavation. Above ground, 14 of 18 bridges are substantially built and 30% of road surface works is already complete. clem7.com.au 1

2 About the CLEM7 Clem Jones Tunnel (CLEM7) is Brisbane s first major road tunnel and the first section of the new M7 motorway. Formerly known as the North-South Bypass Tunnel, Brisbane City Council re-named the tunnel to recognise the enormous contribution made by Brisbane s longest serving Lord Mayor, Clem Jones. Clem Jones served as Lord Mayor from 1961 to 1975, overseeing the city s growth from a sleepy country town to a vibrant subtropical city. M7 He was a great advocate of progress and was responsible for Brisbane s first town plan. His achievements include establishing sewerage, water and road networks. Clem Jones passed away in 2007, aged 89. Scheduled to be open in 2010, the tunnel will link to five major roads on the north and south sides of the Brisbane River which together carry 400,000 vehicles every day. The benefits Motorists using the CLEM7 will enjoy faster, safer and more reliable travel as they avoid up to 18 sets of traffic lights and reduce their travel times by up to 30% Reduced stop-start traffic on congested roads will lower fuel costs and reduce wear and tear on vehicles Businesses delivering goods to customers, tradesman trying to get to their next job and taxi drivers will benefit from improved travel times, reduced operating costs and predictable travel CBD M7 M1 The additional river crossing and much needed bypass of the Brisbane CBD will reduce congestion on the traffic network M3 Local communities will benefit from new and upgraded bike and pedestrian paths, and improved local road connections CONTACT US For more information about the project: Call us on Visit the website clem7.com.au Or contactus@nsbt.incite.com.au For investor enquiries please call

3 CONSTRUCTION REACHES TOP GEAR There are now more than 1,500 people working above and below Brisbane streets constructing the CLEM7. Almost five kilometres of tunnel has been excavated by the project s tunnel boring machines and roadheaders. Activity Total advance by tunnel boring machines Progress 2.4 kilometres The project remains on target to complete all bridges at either end of the tunnel by the end of The construction team has been installing noise walls, cycle paths and street lights. Landscaping has also commenced with more than 250,000 trees, shrubs and ground cover plants to be planted prior to the CLEM7 opening.

4 Brisbane tuff not so tough The two massive tunnel boring machines digging the CLEM7 are finding Brisbane Tuff not so tough after eating their way through more than 550,000 tonnes of the City s hard rock. Tunnelling four kilometres from Bowen Hills to Woolloongabba, Matilda and Florence have each advanced more than 1.2 kilometres. Both tunnel boring machines and are now excavating rock and placing tunnel lining more than 50 metres below Brisbane s Fortitude Valley. The tunnel boring machines remain on track to be under the Brisbane River by September The machines are expected to breakthrough at Kangaroo Point in late 2008 and then finish their journey at Woolloongabba by mid To date, more than 19,000 concrete tunnel lining segments have been manufactured, which is more than 50% of the total number to be produced at the project s factory in Eagle Farm. 1 Rock excavated at the tunnel face is removed via an internal conveyor that runs the length of the tunnel. 2 38,000 concrete segments each weighing 8.5 tonnes will be used to fully line the 4.8km twin tunnels. 3 Tunnel boring machine operators use laser guidance systems to direct their journey below Brisbane streets. 4 A mini-tunnel is being constructed below the road surface to carry electrical, telecommunication and other cables. 5 Cross-passages are excavated every 120 metres to provide a connection between the twin tunnel tubes. 6 Each of the two tunnel boring machines is 12.4 metres in diameter, weighs 4000 tonne and is 261 metres long. 4

6 Roadheaders making excellent headway Roadheader tunnelling is well advanced with 70% of the excavation now complete. At Kangaroo Point, 90% of the rock has been excavated on the two kilometre section of tunnel that will create the Shaftson Avenue on and off ramps and sections of the mainline tunnels. With the majority of the excavation now complete, final lining work has commenced including the installation of the waterproofing membrane, lattice girders, shotcrete and cast in-situ concrete tunnel walls. Tunnellers working at the Woolloongabba worksite have excavated 500 metres of tunnel as they dig sections of the northbound and southbound tunnel towards the Pacific Motorway and Ipswich Road. 1 Tunnel lining work has now commenced at Kangaroo Point. 2 Eight roadheaders working at Kangaroo Point and Woolloongabba will excavate 25 percent of the tunnel. 3 Tunnellers at Woolloongabba are excavating south towards the Pacific Motorway and Ipswich Road of the 18 bridges being constructed at either end of the tunnel are now substantially complete. 5 The construction team will install a total of 1,100 bridge deck units. 6 When complete, the 3-level northern interchange will carry more than 100,000 motorists every day. 6

7 Bridges provide smooth tunnel ride Eighteen bridges being constructed at either end of the CLEM7 will provide smooth access for motorists as they enter and exit the tunnel. The first section of the CLEM7 s northern interchange opened to traffic in April Providing a direct link north from the Inner City Bypass to Lutwyche Road, it is the first of 11 bridges that together create one of the largest traffic interchanges in Brisbane. When complete the 3-level northern interchange will cater for more than 100,000 motorists every day. The interchange will also provide a direct connection between the Clem Jones Tunnel and the planned Airport Link tunnel. This will enable motorists to travel from Woolloongabba to the Airport without passing through a single set of traffic lights. At the southern end of the tunnel Woolloongabba residents are now benefiting from a new local bridge and bike path, which were opened by the project at the end of May All 18 bridges will be substantially complete by the end of BRIDGES Total number of bridges 18 Number of bridge beams 350 Super T bridge beams Length of bridge beams 25 kilometres if placed end-to-end Number of bridge deck units 1,100 Biggest bridge beam 39 metres long and weighs 75 tonne 7
