In combination with the design example of Pudong International Airport's north passageway---the A20 interchange bridge, this paper analyzed and researched the relevant key technologies. It can be seen that the key technologies adopted in the A20 interchange bridge are of advanced technology and practical value in China, they are as follows: the overall interchange plan of“whole turbine type plus rhombus combination”, the ramp inlet and outlet plan of“merged entry and exit by two grades of split-flow and inter-flow”, the soft subsoil treatment measure of T-shaped bidirectional soil-cement mixing piles, the drainage asphalt pavement of“OGFC drainage pavement plus waterproof synchronized gravel seal coat”, the butterfly-like curved continuous box girder with big cantilever, the bridge landscape design with“golden section” concept, and so on.
