comment

Connecting Heping District and Hedong District, it is a bridge that not only meets the traffic function but also has landscape effect. The Heping District of the bridge starts from Jiefang North Road, along Baoding Road to Taierzhuang Road, and crosses the Haihe River and the planned Haihe East Road (underground tunnel) in the form of single-tower cable-stayed bridge. One side of Hedong District was affected by the demolition of South Railway Station, and a temporary approach road was temporarily laid to bypass Haihe East Road.

The total length of the bridge is 23 1m, and the total bridge area is 1 1.600 m2, of which the bridge area is 6,778 m2 and the road area is 4,822 m2.

geographical position

Baoding Bridge sinks across Taierzhuang Road on the west bank of Haihe River, lands on Jiefang North Road and connects Baoding Road in Heping District. The east bank passes through the business circle of South Station in Hedong District and ends at Liuwei Road in Hedong District. The main span of the bridge is 1.20 meters, with the roads on both sides of the bridge, the total length is 570 meters. The most striking thing about the whole bridge is the "sail"-shaped main tower at the bridgehead on the west bank, which symbolizes that Tianjin, an international port metropolis, is braving the wind and waves and becoming increasingly prosperous. The main tower is 50 meters high and leans 75 degrees to the west. The shape of the tower is simple. This bridge has no piers in Hanoi, but the deck is "pulled up" by the tension of cables. These stay cables incline downward from the top of the main tower to the center of the bridge deck in the form of sparse cables. Six stay cables are connected to the bridge deck of the main span, and the cable spacing is15m.
