ANZAC BRIDGE 2011

The ANZAC Bridge is a Sydney icon and an important part of the road network. It is now fifteen years since the ANZAC Bridge opened to traffic and Roads and Maritime Services (formerly Roads and Traffic Authority) has prepared a maintenance program to ensure its effective operation into the future. This 3D animation shows what we're planning for the ANZAC Bridge.

Soft soil engineering on the Ballina bypass

Innovative soft soil treatment

The Ballina region is characterised by complex geotechnical conditions, including deep soft soils in the flood plain areas.

Soft soils have been an important consideration throughout the design and construction phases of the Ballina bypass project.

Innovation in Roads 2011

Innovations in Roads explains several recent innovative techniques used on Roads and Maritime Services (formerly Roads and Traffic Authority) road projects. The techniques featured are:

• CFA piling (Tarcutta bypass)
• Moveable barrier system (Inner West Busway)
• Treatment of underground mines and construction of high bridges (Hunter Expressway)
• Diamond grinding (various road maintenance projects)
• Treatment of soft soils including vacuum consolidation (Ballina bypass)

CFA piling on Tarcutta Bypass

Continuous flight auger (CFA) piling was used by Roads and Maritime Services (formerly Roads and Traffic Authority) on the Tarcutta bypass project. CFA piling cost less than traditional methods, was notionally twice as fast as traditional piling methods, was almost vibration free and only created low levels of noise. This was important for project workers and especially for surrounding residents.

Moveable Barrier Inner West Busway - 2010

Sydney's Inner West Busway project saw Roads and Maritime Services (formerly Roads and Traffic Authority) introduce a brand new road technology to Australia. This technology is called the Quickchange Moveable Barrier System, and it creates a dedicated citybound bus lane in the AM peak traffic period.

Treatment of underground mines and construction of high bridges 2011

The Hunter Expressway project presented many engineering challenges for Roads and Maritime Services (formerly Roads and Traffic Authority), including underground mines. The treatment of these mine voids and the construction of high bridges minimised the projects impact on the the Hunter's natural and cultural environment.

Diamond grinding (various road maintenance projects) 2011

In March 2009 Roads and Maritime Services (formerly Roads and Traffic Authority) conducted a trial of the diamond grinding technology to see if there was a large difference in noise levels after the grinding process. This was the first time this technology was used in Australia.

M5 East filtration plant

The filtration equipment will filter and clean approximately:

• 200 cubic metres of air per second to remove at least 80% of particulates less than 10 microns in diameter from the westbound tunnel.
• 50 cubic metres of air per second to remove at least 90% of nitrogen dioxide.

Alfords Point Bridge duplication construction time-lapse 2007

The Alfords Point Bridge duplication was designed to ensure compatibility with the existing structures and looks similar to the existing bridge. Construction work for the bridge duplication was undertaken by Abigroup.

The project was completed and opened to traffic on 21 August 2008.

Hunter Expressway - Fly-over from east to west

This animation and next animation are created from the 3D model that is based on the road design data for the Hunter Expressway. The 3D model gives an accurate representation of the road design, bridge structures and interchanges of the expressway. The resolution of these animations is reduced to 400x244 for the web. Read More >>
