WebQianshanhe River Bridge ( Fig. 2.10 D): The Qianshanhe River Bridge is a three-span continuous box girder bridge with main girders consisting of a single-box cross-section. It is 340 m in overall length, 160 m in maximum span, and 15.75 m in width, 9.5 m in height at the pier top and 4.0 m at mid-span. WebVehicle impact loads under the bridges are not considered in the de sign of bridge superstructures and piers. Many bridges built more than 20-30 years ago have inade quate circulation clearances causing the safety and circulation problems of old bridges. In addition to bridge damage, vehicle/bridge collisions may result in
