Bridges

With transport as Australia's second largest source of greenhouse gas pollution [1], there are some more obvious sustainability benefits in the provision green transport infrastructure. Pedestrian and cycle bridges may be thought of inherently 'green' as they provide a missing link to make communities less car dependent and contribute towards reducing traffic and congestion.

Beyond consideration to the active mode of transport on the bridge, there are many principles that can be applied to active transport bridges to improve overall sustainability outcomes.

Through examining two active transport bridge case studies; the Kangaroo Point Green Bridge and the Indooroopilly Riverwalk; this paper explores various social and environmental principles of sustainability and demonstrates how these can be applied on projects on both a macro and micro level to make a positive impact on communities and the planet.

The study demonstrates that sustainability principles can be applied in many ways on active transport bridges and encourages engineers and planners to think outside just achieving code compliance to drive exceptional sustainability outcomes on projects.
