In this paper it is shown that recent progress in stochastic modeling and optimization in combination with advanced computer systems has now made it possible to improve the design and the maintenance strategies for infrastructure systems. The paper concentrates on highway networks and single large bridges. United States has perhaps the largest highway networks in the world with more than 6 million kilometers of roadway and more than 0.5 million highway bridges; see [2]. About 40% of these bridges are considered deficient and more than $50 billion is estimated needed to correct the deficiencies; see [12]. The percentage of substandard bridges deemed to require urgent actions in other countries such as Prance (15%) and UK (20%) is also high; see [3].
