Roads, Bridges & Structures
We have delivered roads, bridges and structures across the country, ranging from remote locations for resource customers to the delivery of major networks that have changed the face of our urban environments. These networks have increased the productivity of the nation by easing traffic congestions.
Our experience ranges from the delivery of new local highways to the major widening of existing strategic routes via traditional and new managed motorway routes. We are Austroads nationally accredited to R5 for road works and B4 for bridge works, which are the highest levels possible.
Applying our advanced design and construction approach has been crucial when delivering some of Australia’s most complex road projects including the nation’s largest – the $4.8 billion Airport Link in Brisbane. Other examples of major transport links that we have delivered to help cities grow and connect include South Road Superway in South Australia, EastLink in Victoria Pacific Highway - Devils Pulpit in New South Wales. and the Great Northern Highway in WA.
We manage logistics, including land acquisition programs, traffic management strategies, earthworks, road works and complex structures. We also have extensive knowledge of concrete pavement construction and slip-forming paving techniques. Our material engineering teams are proficient in materials processing and committed to maximising the use of recycled materials and secondary materials wherever possible. John Holland has an extensive fleet of vehicles and plant to undertake the works.
Through genuine consultation and community engagement, our team has built a reputation for addressing community priorities and achieving best-practice environmental and social outcomes on major road projects across Australia.
BRIDGES & STRUCTURES
The design and construction of the South Road Superway is one of Australia’s longest elevated roads and considered to be South Australia’s most complex engineering road construction project. The elevated roadway is a significant structure that enhances the surrounding environment. It features long spans, fluid pier shapes, integrated landscaping, parapets, lighting and gantries, all contributing to an outstanding urban design solution fully integrated with the structural design.
The strengthening of Melbourne's iconic West Gate Bridge has significantly enhanced the structure's longevity. It features the largest application of carbon fibre to a bridge structure in the world. This project is one of the most complex, high-risk engineering design and construction projects undertaken in Australia. Construction innovations included the development of Australia’s first bridge-specific design standard and loading standard. The project also incorporated a world-first calibration method for structural modelling, using dynamic modelling and field accelerometer readings.
We carefully take into account ground conditions, structural components, pre-casting and prefabrication, traffic, and environmental and safety requirements during the design phase, to develop specific construction methodologies that minimise impact to the environment and locals whilst deriving cost savings and facilitating early asset utilisation.
