Abstract:

Australia has one of the most extensive road networks in the world with some 37,000 bridges. The bridges have relatively short spans by comparison with other continents.

Bridge engineering has undergone a significant evolution in the past decade. New developments have led to reduction in costs, improvements in safety and lower environmental impact. The development of the prestressed concrete Super T-beam system has made the greatest impact capturing a large market share in a short time. Advances in the design and construction of steel bridges have also made these more competitive. Perhaps the most significant innovation is the “pier-redundant” bridge, a concept with unmatched safety in the event of pier collapse. These developments have potential application in the USA and around the world.
