Take the tram to go, the way to the broadcast will be introduced, the Liede Bridge main bridge is a single tower double cable space self-anchored suspension bridge, the total length of 480 meters. The bridge shell-like three-dimensional curved tower body shape is unique, ranking second in the world and first in the country. The construction process of the Pearl River Bay "three-dimensional curved water-cleared concrete cable tower is very difficult; the construction process of the steel stiffening beam top push is relatively new; the construction process of the asymmetric space self-anchoring cable system is complicated. With the completion of the installation of the asymmetric main cable in the whole bridge and the fine tuning of the cable tension and cable force All completed, marking the three major technical difficulties of the Liede Bridge have been overcome.
