The project was one of the largest components of the major ongoing capital works program upgrading one of Queensland’s busiest roads.
The 11km project was a combination of brownfield and greenfield work, including three bridges, 8.7km of new road alignment and construction of approach embankments. The works involved 200,000m3 of fill, 140,000 tonnes of cement treated base, 180,000 tonnes of asphalt, stormwater reticulation, installation of 18km of concrete barrier, street lighting and Intelligent Transport System services.
Key project elements included:
- Complex management of multi-lane carriageways and grade separated interchanges at the newly constructed on and off ramps
- The project team achieved the Queensland record for highest average asphalt productivity over the project, and met all quality requirements
- Establishment of an onsite batch plant that took traffic movements off the Highway, thereby improving safety and traffic flow for motorists.
- All bridges required deep piling to 18 metres. One bridge, constructed over live traffic, was a super-T with driven precast piles. The remaining two bridges consisted of driven precast concrete piles and cast insitu decks.
The project was completed one month ahead of program and to budget.
