PROSPERITY^® is responsible for the fabrication and on-site assembly of two-thirds of the arch seats, tail end box girders, columns, arch aid plane sections and bridge deck plane sections of the bridge. The arch seat is the box-shaped structure with the highest quality standard and the greatest processing and manufacturing difficulty among all the compartments of the Lupu Bridge. It is composed of a 50mm thick top plate, bottom plate, back plate, end plate, partition plate, and auxiliary plate made of fine-grained normalized S355N material. The weld grade is 100% ultrasonic testing and 25% radiographic testing.

63.The Beixingtang Bridge is a continuous steel bridge structure system with a total width of 425 meters. The entire bridge is divided into two steel truss girders, the north and the south. A single steel girder is composed of several parts, including the main truss, upper (lower) horizontal and longitudinal links, bridge portal frame, transverse links, and bridge deck system (longitudinal and transverse beams). It is 88 meters in total length, with the center height of the upper and lower chord members of the steel truss girder being 11 meters. The height-span ratio is 1/8, and the center distance between the two main trusses is 21.5 meters, with a width-span ratio of 1/4.09. The upper and lower chord members and end diagonal members of the main truss all adopt box sections, with a section width of 500mm, a height of 720mm, and a maximum plate thickness of 50mm. The main truss adopts a sliding wheel type triangular web member with vertical members, with an interval length of 8 meters. Except for the end inclined web member, the cross-sections of the other web members are all welded H-shaped cross-sections, with a cross-sectional width of 500mm, a height ranging from 420 to 720mm, and a maximum plate thickness of 44mm. Both the upper and lower plane longitudinal connection systems adopt the double X form. The cross-sectional forms of the connection system members are all welded H-shaped cross-sections, with a cross-sectional height of 400mm and cross-sectional widths of 300mm and 400mm. The plate thickness ranges from 12 to 24mm, and all connection forms are insertable connections. Bridge and gantry frames are set in the inclined planes where the diagonal members at both ends of the truss are located, and a transverse connection system is set for every two upper chord nodes. The bridge deck system adopts a longitudinal and transverse beam system. The crossbeams are welded H-shaped sections with a height of 1050mm. The web plates of the crossbeams and the main trusses are connected at the nodes through high-strength bolts. The longitudinal beam is a welded H-shaped cross-section with a height of 500mm. The web of the longitudinal beam and the web of the crossbeam are connected by high-strength bolts. A longitudinal beam is set every 2 meters in the transverse direction of the bridge. A secondary crossbeam is set every 2 meters between sections. All steel plates are made of 14MnNbq, and Angle steel, channel steel and other section steels are made of Q345B.
