Lupu Bridge, like a beautiful rainbow, spans the banks of Pujiang, adding a new landscape and symbol to Shanghai. The bridge also set a record of 10 as "the best in the world".

Lupu Bridge is the largest steel arch bridge in the world and the second longest steel arch bridge in the world. It is also the world's first large-scale arch bridge completely connected by welding industry. The total length of on-site welds (except the bolted connection of the closure interface) exceeds 40,000 meters, which is close to the total length of Shanghai Inner Ring Elevated Road.

Lupu Bridge adopts river-crossing design mode. Its main span is 550m in diameter, 9m in section and 5m in width. It can be considered as the largest steel arch bridge in the world. The main bridge has six lanes. Under the bridge, 70,000-ton ships can pass. The blueprint of Lupu Bridge is cable-stayed bridge and suspension bridge. The main design is mainly welded steel frame structure with a total investment of more than 2 billion yuan.

Lupu Bridge, the first arch in the world, has the same sightseeing function as Sydney Bay Bridge in Australia. Lupu Bridge will install a sightseeing platform at the top of the arch rib like a huge bow. It not only makes the sightseeing height higher, but also requires tourists to walk more than 300 steps along the arch rib "slope", which increases the sightseeing interest and sports.
