This paper presents a practical approach for prioritization of bridge maintenance within a given bridge network. The maintenance\nprioritization is formulated as a multiobjective optimization problem where the simultaneous satisfaction of several conflicting\nobjectives includes minimization of maintenance costs, maximization of bridge deck condition, and minimization of traffic\ndisruption and associated user costs. The prevalence of user cost during maintenance period is twofold; the first case refers to the\nperiod of dry season where normally the traffic flow is diverted to alternative routes usually resurfaced to regain traffic access. The\nsecond prevalence refers to the absence of alternative routes which is often the case in the least developed countries; in this case the\nuser cost referred to results fromthe waiting time while the traffic flow is put on hold awaiting accomplishment of the maintenance\nactivity. This paper deals with the second scenario of traffic closure in the absence of alternative diversion routes which in essence\nresults in extreme user cost. The paper shows that themultiobjective optimization approach remains valid for extreme cases of user\ncosts in the absence of detour roads as often is the scenario in countries with extreme poor road infrastructure
