ACCIONA, together with its partners Plenary Group and Cintra Infraestructuras, has inaugurated the final section of the Toowomba Second Range Crossing project in the Australian state of Queensland. The motorway is now completely open to traffic and has received an associated investment of AUD1.6 billion (around US$1.1 billion).
In July 2015, the Nexus consortium comprising ACCIONA, Plenary and Cintra was selected for the design, construction, financing, operation and maintenance of the Toowoomba crossing, the largest road project in the state of Queensland. The financial close took place in August of the same year. ACCIONA and Ferrovial Agroman were in charge of the design and construction. Broadspectrum will be in charge of its operation and maintenance. The concession covers 25 years.
The Toowoomba Second Range Crossing is an alternative crossing of the Toowoomba Range for all classes of heavy and super heavy vehicles to improve freight efficiency and driver safety, relieve pressure on Toowoomba’s roads, and enhance liveability for residents of the city and its near neighbour Withcott in the Lockyer Valley.
The Toowoomba Second Range Crossing is 41 kilometers long and will improve the region’s traffic flow by reducing heavy vehicle circulation in the city center. The first section of the Toowoomba bypass was opened in December 2018.
The Toowoomba Crossing stretches across the Great Dividing Range, which runs roughly parallel to the country's east coast for 3,700 kilometers. Users of the Second Range Crossing will cover the 500-meter difference in altitude between connection roads on slopes with gradients of no more than 6.5%, avoiding the steeper 10% level deviations and the 18 traffic lights of the existing road, which crossed the city. This infrastructure will make it possible to reduce the traveling time of heavy vehicles on the East-West corridor by around 40 minutes.
Among its technical highlights is an 800-meter viaduct over a railway line, and a mountain cutting that, by avoiding the alternative of a tunnel, will allow the circulation of heavy vehicles or those transporting hazardous cargo.
