Nanpu Bridge was put into use in 1991 as the second largest cable bridge in the world. The complexity and advanced level of technology were rare in bridge construction in China. After more than 20 years of use, the Nanpu Bridge experienced some problems such as component wear.
In addition to regular maintenance, the Nanpu Bridge has added a lot of new equipment. 203 sensors throughout the bridge reflect the structure and operational status of the bridge at any time.
Nanpu Bridge has a navigation function. In the 1990s, the Nanpu Bridge installed only five red lights on the outside of the main bridge as a navigation aid. According to the current national standards, a navigation aid sign is built to reduce the risk of the bridge being hit.
In order to prevent the bridge from deformation, the Nanpu Bridge is equipped with a device to relieve the thermal expansion and contraction of the bridge. Because of the uneven settlement of Pudong and Puxi ground and heavy traffic, the device on the west side of the bridge is seriously damaged and will replaced by a new type of a new material expansion device.

The speed limit is 40 kilometres per hour on Nanpu Bridge. The two- meter-wide sidewalks on each side of the main bridge are useful for people to go sightseeing. Visitors can take the elevator to the main bridge to enjoy the beautiful scenery on the Huangpu River. Nanpu Bridge is the earliest bridge across the Huangpu River in Shanghai city.
Shanghai people treat Huangpu River as the mother river which is the source of Shanghai growth and civilization. The great river separated Shanghai into two parts-backward Pudong District and the thriving Puxi District. Many generations in Shanghai dreamt of there being a big bridge linking the two districts.
The idea of building a bridge has become stronger and stronger since the 1920s. In 1975, Songpu Bridge was built. It reduced pressure temporarily it did not solve the problem of busy traffic on the Huangpu River because it was too far from the central city area.
The idea of building another bridge over the Huangpu River became the focus and was put onto the agenda. In August 1986 the state council approved the application to build the Nanpu Bridge project. In 1990, the Chinese government decided to build Pudong District into a major development area, the building of Nanpu Bridge became an even more important project that must be completed.
