The development and application of precast, prestressed concrete bridges is different in various countries. The United States, Canada, Japan, and many European countries routinely use precast, prestressed concrete bridges, while other countries do not yet have this technology. Although South Korea has used precast concrete bridges since 1965, complete information on this method of construction has not been available to South Korean engineers. Precast, prestressed concrete box-beam bridges present many advantages over traditional bridge construction, such as easier and faster construction, minimized fieldwork, and lower cost. This paper introduces recent research into the development and application of precast, prestressed concrete box-beam bridges in South Korea, the first of which was constructed in 2005. Static and dynamic field tests were conducted on this new bridge before it opened to traffic, allowing for the study of the behavior mechanisms and assessment of its structural performance under various service loads.
