摘要：
A pre-stressed concrete bridge using longitudinal load members of a single continuous beam including at least two types of concrete, one of which is ultra-high-performance concrete (UHPC) mix with a compressive strength exceeding 20 ksi and tensile strength exceeding 1.5 ksi in a region proximate to the support structure.
