A Strategy for Upgrading Bridge Infrastructure Network
MetadataShow full item record
Bridges are important links in the road network. Over the years, bridges have been designed to various standards as they were built in different periods. The road infrastructure grew as the country developed and the population spread out. The technology also has significantly developed resulting in better understanding of bridge structures and their behaviour. As funds availability is tightened, road authorities are facing challenges related to the implementation of optimal bridge management programs based on lifecycle cost, remaining life and bridge capacity considerations. In this context, this paper presents the Australian experience in managing bridges, and proposes a strategy to upgrade bridges on sub-networks in a proactive way in anticipation of new operational loads or legal limits being imposed. The paper also provides an example illustrating the applicability of proposed strategy.
