4th Nanjing Yangtze Bridge

Übersicht

Project description

The Fourth Nanjing Yangtze Bridge crosses the Yangtze River near the city of Nanjing in eastern China. The Yangtze is crossed by a number of major suspension bridges near Nanjing, where it has a great width despite being over 300 km from the coast.

Having previously supplied modular expansion joints for the Second Nanjing Bridge in 2000 (20-gap joints), and the Third Nanjing Bridge in 2005 (13-gap joints), mageba, and the TENSA-MODULAR joint in particular, already had a strong record of proven performance in the region.

The main structure is a three-span continuous suspension bridge with a main span of 1,418 m.

mageba scope

To facilitate the enormous longitudinal deck movements of 1,920 mm at both ends of the cable supported structure, mageba supplied four TENSA-MODULAR expansion joints of type LR19 (each with 19 individual gaps between surface beams).

Each joint has a length of 16 m, and two joints placed end to end span the movement gap at each end of the structure, one for each carriageway.

The joints were manufactured in mageba’s Shanghai factory, just 250 km from the bridge.
