All hands on deck as Cairns highway project progresses
Federal Leichhardt MP Warren Entsch said the new inbound bridge, which was expected to be completed by mid-2020, boasted several interesting features.
“The 90 bridge decking units are manufactured with a slight upwards curve that flattens out when placed,” Mr Entsch said.
“This construction technique prevents sagging and ensures a strong, flat foundation for the road.”
Deputy Prime Minister Michael McCormack said the works were a major step forward in the $104.1 million project.
“These huge decking units are the backbone of the superstructure and connect the new inbound bridge from end to end Mr McCormack said.
“The units weigh up to 31 tonnes, measure 24 metres in length and are larger than a humpback whale.
“Two cranes – both weighing more than 200 tonnes – are needed to install the decks, which will be completed mostly at night to minimise disruption to motorists.”
The Cairns Southern Access – Stage 4 project (Kate St to Aumuller St) is jointly funded, with the Australian Government committing $83.3 million and the Queensland Government $20.8 million.
The principal construction contract was awarded to the Georgiou Koppen Joint Venture.
Works include widening this section of the Bruce Highway from four to six lanes to reduce travel times and improve safety.
It is expected to be fully complete by mid-2021, weather permitting.
