The Straßenbrückenzug consisting of the suspension bridge with a length of 2.7 kilometers and the subsequent access bridges on both sides, has a total length of 5.3 kilometers. It connects to four lanes in China and the islands Jintang Cezi the archipelago Zhoushan in the East China Sea.

Construction

The main bridge is a suspension bridge with a total length of 2713 m. The central hole has a main span of 1650 m. A special feature of the bridge is its asymmetrical design in the side panels. In the northern field with 578 m length of the road depends, as usual, on the supporting cables. In contrast, the track support is at the 485 m long southern field that is already on the island Jintang, supported on pillars. The 36 m wide, aerodynamically designed roadway carrier has two steel box-girder cross-sections of 3.26 m in height, which are arranged in a clear distance of 6.0 m and connected by cross beams. The pylons have a height of 211 m and are based on each of 24 bored piles of 2.8m diameter. They are made of reinforced concrete and are connected by three cross bar rigidly to each other in the transverse direction. The support cables hold up to 87 cm in diameter. The clearance height for ships at high tide is 49.5 m with a clear passage width of 630 m.
