Bridge material selection is the most important decision for a bridge designer in terms of long-term consequences. As new materials enter the market for bridge applications, a thorough understanding of a highway official's perception of the materials will allow manufacturers to better accommodate their needs. Perceptions of major bridge materials by three distinct groups of decision makers were studied within five geographic regions in the United States. Prestressed concrete, steel, timber, and reinforced concrete were the materials compared. Bridge materials were compared on perceived performance as well as eight other preselected attributes. Important factors in the bridge decision process were identified. Comparisons were made on decision making group and geographic region. Overall, the highest perceived performance was earned by prestressed concrete followed by reinforced concrete, steel, and timber. Perceptional maps provide insight for those manufacturers hoping to improve their perceived performance. Areas of future research for bridge materials were identified.
