The main objective of the research was to study the economic viability of West Virginia Fiber Reinforced Polymer (FRP) bridge decks. Life‐cycle cost of those bridge decks were estimated for conducting such analysis. Three main differences that distinguish the way the life‐cycle cost of FRP deck was estimated are: (1) the manufacturing cost of a FRP bridge deck was estimated using learning curve theory; (2) cost savings in support structures when FRP is chosen as opposed to the alternative bridge deck was modeled; and (3) the service life was estimated based on factor method to minimize the subjectivity of the estimates. The three case studies for West Virginia FRP deck projects show that based on the estimated life‐cycle cost, FRP decks are financially viable under certain conditions
