The NSBT will:
* address existing and predicted future congestion levels in and around the city
* remove a significant amount of vehicles from the existing surface roads in the city
* complete a CBD bypass and inner city ring road system
* deliver a better network for pedestrians, cyclists and public transport
* free up road space to enable opportunities for public transport and other modes of transport along the NSBT corridor
* save motorists up to 15 minutes on a cross-city trip and reduce the peak-hour travel time across the City
* enable motorists to avoid 18 sets of traffic lights
* improve air quality in the city by reducing surface traffic
* enable regeneration of urban centres in Woolloongabba, Bowen Hills and Kangaroo Point
* employ more than 1,200 people at the peak of construction
* allow the people of Brisbane and Queensland to invest in the road through a public share offer
* include state of the art electronic tolling, interoperable with other Australian electronic toll roads
* create new standards in tolling customer service, particularly in convenience, flexibility and transparency.

WORLD’S BIGGEST HARD-ROCK TUNNELLING MACHINE HEADING TO BRISBANE 3 MONTHS EARLY
The world’s biggest hard-rock tunnelling machine is set to start work on Brisbane’s North-South Bypass Tunnel three months ahead of schedule, following its early manufacture in Germany. Parts of the $A50 million machine have already started arriving in Brisbane where it will be reassembled
on-site and commence tunnelling in December 2007, well ahead of the original
construction program of March 2008.
RiverCity Motorway Chief Executive Officer, Flan Cleary, said the early manufacture and delivery of the 4000-tonne tunnel boring machine was another key milestone for the project. It follows the commencement of roadheader excavation in February 2007, two months ahead of schedule.
“With a 12.4 metre diameter cutting head, equivalent to a 4-storey building, and a body that is 250 metres long these machines truly are tunnelling juggernauts,” Mr Cleary said. “Each machine weighs as much as 2,350 family cars. The task ahead of them is just as enormous when you consider that we will be excavating enough rock to fill the Brisbane Cricket Ground (the
Gabba) nine times over.” Approximately 3.5 million tonnes of rock will be removed to construct Brisbane’s first major road tunnel.
Two hard-rock, double-shield tunnel boring machines will complete up to 70 percent of all excavation, with seven roadheaders being used for the remaining works. Mr Cleary said the manufacture of the second tunnel boring machine was currently three months ahead of schedule, with plans for this machine to commence excavation in March 2008. Each machine will start on the north side of the Brisbane River at Bowen Hills and travel south, finishing at Woolloongabba. Mr Cleary said the German manufacturer of the tunnel boring machines, Herrenknecht, had been designing and manufacturing the tunnel boring machines since August 2006.
“The machines are being purpose-built to meet the specific requirements of the project and the geological conditions along the North-South Bypass Tunnel route,” he said. “By selecting double-shield machines we are able to excavate rock and place the concrete tunnel lining at the same time. This means the tunnelling operation is both efficient and safe.” A team of 21 people per shift will operate each tunnel boring machine 24-hours per day, Each machine is expected to advance up to 20 metres per day.
The North-South Bypass Tunnel is part of Lord Mayor Campbell Newman’s long-term plan to improve Brisbane’s transport network by providing new river crossings and connecting existing motorways and major arterial roads.

That is one big tunnel (for Australian standards) and I agree with Mants on its roof design. I'm actually surprised its only 2 lanes in width, because considering SEQ population growth, there would be a substantial increase in traffic congestion, which would undoubtedly place the NSBT under pressure upon its opening.
Yeah... the loosing bid was a design for 3 lanes for only 20 million more! an extra 20 million is nothing compared to the 2 billion cost of it. I actually hoped for a 2 lane 2 rail tunnel... but that never happened.
