Formatted Abstract/Summary
Sustainable infrastructure requires that it is managed to have maximum total benefit, i.e. now and in
the future, and to all stakeholders. If the benefit of intervention strategies to be compared can be
considered the same, then sustainable infrastructure is infrastructure that is managed to have minimum
total cost, i.e. the minimum negative economic, environmental and social impacts.

The main challenge, with respect to bridges, is to determine the most sustainable intervention
strategies adequately taking into consideration the impact on humans of bridge performance, and
changes in bridge performance. This is particularly challenging with bridges when compared to other
types of infrastructure due to the wide variety of elements and materials, long service lives, and
normally long periods between interventions. Some costs and impacts depend on actions that are
applied to elements directly (such as concrete repair, energy of repair material manufacture), while
other costs and impacts vary indirectly with elements (such as traffic control, user costs, noise,
emissions). A methodology is proposed in this paper that overcomes these challenges and provides a
measure of the long term sustainability view. To demonstrate the proposed methodology, the most
sustainable intervention strategy for a steel bridge is determined.
