This paper introduces the design of a reinforced concrete slant-legged rigid frame bridge built in a county town. The bridge shape and structural project were selected considering factors such as hydrology, environment, art expression and construction technology. The design software MIDAS Civil 2006 was applied to build the numerical model for analyzing the static and dynamic properties of the bridge structure. The results show that the loading performances of the bridge satisfy the specifications of current Chinese design codes. The bridge was constructed and had been operating since Oct. 2008. Now, it becomes a landscape of the county town.
