The Yingxiu-Wenchuan Expressway is located in extremely stricken area of the “5 · 12”Wenchuan earthquake. Based on investigation for seismic disasters of bridges in Wenchuan earthquake stricken area and in combination with design of bridges on Yingxiu-Wenchuan Expressway, this paper introduces how to select bridge locations and determine bridge type schemes in high-intensity seismic areas and proposes new major seismic prevention and disaster mitigation measures including structure for preventing bridge collapse and seismic reduction and isolation techniques, etc. These measures have achieved good application effects in practical projects and can be popularized in expressway projects of the same type.
