description
The Dazhi Bridge is an unusual, asymmetrical suspension bridge. With a span of 500 m, it only has a classic concrete pylon on the north bank of the river, where - unlike pillars in the middle of the river bed - scouring is avoided. The two suspension cables that run over him are attached to the ground in anchor blocks about 80 m behind him . The function of the other pylon is taken over by anchor blocks on a mountain ledge approx. 90 m south of the bridge, with a concrete block on a ledge approximately halfway preventing the suspension cables from resting on the mountain.
The carriageway girder is therefore significantly shorter than the span at around 420 m. It is 4.5 m wide and therefore only leads one lane over the river. It is designed as a lattice girder for stiffening. The roadway consists of slightly profiled sheet steel. Some inclined ropes are stretched between the pylon or the mountain ledge and the roadway to stiffen the road girder.
The bridge and connects the national road G 318 with the provincial road S 202 ( Shengdao 202 ). The next possibility to cross is about 250 meters further west, the New Dazi Bridge (the S 202 is now passed over it). The building is also considered a tourist attraction; not least because of the eye-catching decoration with colorful Tibetan prayer flags , which are also offered by dealers on site (at the entrance to the G 318).
