      The bridge adopts the construction form of "bridge, island and tunnel in one"; the whole section of the bridge presents S-shaped curve, and the axial direction and flow direction of the bridge pier are roughly equal, which can not only alleviate the driver's driving fatigue, but also reduce the resistance of the bridge pier The water rate can also improve the beauty of the building. The designed service life of the bridge is 120 years, which can withstand 8-magnitude earthquake, 16-magnitude typhoon, 300000 ton impact and 300 year flood tide at the Pearl River mouth.
