Wildlife friendly design of road structures

Many road projects cross watercourses and wildlife corridors that are important for the survival of native wildlife. Insensitive construction of the road structures that cross such watercourses and wildlife corridors can sever both fish and fauna passage. Thus a considerable variety of our unique native wildlife, especially kangaroos, wombats, koalas, platypuses and cassowaries, are killed annually on Australian roads. In addition to these wildlife mortalities, road user fatalities occur annually when motorists lose control of their vehicles after hitting or swerving to avoid wildlife obstructing the carriageway. The authors present the key issues affecting 'wildlife friendly' design of road structures - particularly for Australian conditions. They elucidate economic and practical design concepts to address those issues and conclude that it is reasonable to provide for wildlife passage in the design and construction of road projects. However they emphasize that 'wildlife friendly' design of road structures cannot substitute for poor road planning. (a) For the covering entry of this conference, please see ITRD abstract no.
