The bow has a peak height of 100 m above the water level.
For the construction of the steel sheet two temporary piers were built of steel at the ends of the bridge, where then the sheet cantilevering element by element was hung back. Only when the arch was completed, this Hilfsabspannung was reduced.

Feasibility Study was in May 2000 and in August before the final design., the " Shanghai Construction (Group) General Co. " the contract to build the bridge was granted. the Lupu Bridge is the first major bridge across the Huangpu, the in -house Shanghai City was built. funding was acquired by private consortia, the city pays only a fixed annual sum, so that the bridge is toll-free navigable.
