Clem 7 Tunnel, Brisbane, Queensland.
Tonight Matt and I, headed to the Clem 7 Tunnel (whilst it's free for the next 3 weeks!) to shoot a series of long exposures in the tunnel.
We developed an elaborate in-car tripod rig, did a few laps around the block to ensure the 5D was secure and so we could achieve a smooth exposure with little vibrations. Matt drove and I set-up the various compositions we had planned to try.
We did approximately 7 trips through the entire tunnel and exiting at every possible exit on the North and South Bound routes.
We came away with some keepers. Here's a link to Matts photo
On entry to the tunnel we noticed the neon sign asking us to tune our radios in (which we found to be 103.7FM) to receive the following broadcast on congestion within the tunnel.
Here is a link to our YouTube video of the broadcast:
- Canon 5D Mk II.
- ISO 100, f4, 0.8 seconds, 17mm.
- Canon 17-40 f/4 L Lens.
- Elaborate Tripod Rig.
- Saturation and Contrast in Photoshop 6.0 and Lightroom 2.2.
About The Clem 7 Tunnel
The M7 Clem Jones Tunnel (CLEM7), known during its development as the North-South Bypass Tunnel (NSBT), is a AUD$3.2 billion toll road built under the Brisbane River, which crosses between the suburbs of Woolloongabba and Bowen Hills in Brisbane, Australia. The CLEM7 Community Open Day, a public open day which included a tunnel run and walk was held on 28 February 2010. The tunnel was progressively opened to traffic from late on the 15th March 2010 until just after midnight on the 16th. It was completely open - all lanes, both directions - by 12.02am.
The tunnel was originally proposed by then Labor Lord Mayor Jim Soorley in 2001, and was incorporated into the Liberal Party candidate Campbell Newman's five tunnel vision, called TransApex in 2002. In December 2007, Brisbane City Council decided to name the tunnel the Clem Jones Tunnel in honour of the former lord mayor. On July 16 2008, the Government of Queensland announced that the tunnel will be known as the M7 Motorway. The M7 name will also be assigned to the Airport Link.
The project is Brisbane’s first privately financed inner city toll road. The road is the city's largest road infrastructure project and one of Queensland's largest infrastructure projects. With tunnel length of 4.8 km it will be the longest road tunnel in the country until the planned 6.7 km Airport Link tunnel is complete.
Construction bids were provided by a tender process in which Rivercity Motorways was selected over the Brisconnections consortium. The project commenced in September 2006, with tunneling using two very large boring machines completing digging by May 2009. The tunnel will be tolled via an electronic tolling system. The tunnel design includes extensive safety systems, a traffic control centre and speed cameras. The price of the toll has been criticised as too expensive and the ventilation stacks as too intrusive.
Construction commenced in September 2006. At the start of the project it was the longest road tunnel being built in the country. 3.5 million tonnes of excavated rock was removed from the tunnel by conveyor, stored in silos and taken away by truck. During a typical weekday period more than 25 trucks per hour have been hauling removed soil and rock along Kingsford Smith Drive to an area near the Brisbane Airport.
During construction all 1700 staff working on the project and all site visitors, who are inside the tunnel, could be located at any time using an RFID tagging system that transmits a person's location wirelessly. The system was designed to monitor site access and asset location as well as to improve safety and efficiency in what is a high profile and potentially hazardous worksite.
Difficult drilling conditions, due to the very hard Brisbane Tuff rock that is found under inner Brisbane, were encountered and overcome. Both purpose-built, double-shield boring machines began on the northern end, with the first arriving in Brisbane in July 2007 and cutting commencing in December after testing was conducted. At the time, the tunneling machines were the biggest in the world, weighing 4 000 tonnes and each being 250 m in length. Each machine cost AUD$50 million to build. The boring machines were built by the German firm Herrenknecht and can dig up to 20 m per day. When finished the boring machines will have placed 37 000 precast linings. Smaller roadheader machines began from the southern end in February 2007.
