Wusong River Bridge section opens after reconstruction

Part of a reconstruction project on the Wusong River Bridge was completed yesterday to improve traffic on the G1503 expressway and connections between Shanghai and neighboring Jiangsu Province.

The western deck of the new bridge opened to traffic yesterday afternoon after more than a year of demolition and reconstruction without disrupting the busy traffic over the river, known as the upstream of the Suzhou Creek, according to Shanghai Tunnel Engineering Co Road and Bridge Group, the city’s major road and bridge builder.

The project is part of the waterway treatment campaign approved by the State Council to improve flood prevention, the ecological environment and transport capacity of the Taihu Lake Stream. The campaign has been listed as a key interprovincial water project for the integrated development of the Yangtze River Delta region.

The cross-river bridge is part of the G1503 beltway around the city in suburban Qingpu District. It connects Anhe Road in Qingpu and Huaqiao in Kunshan, Jiangsu.

The old bridge was built in 2004 as the major channel between Shanghai and Jiangsu. More than 4,400 vehicles use the bridge per hour during rush hour, numbers the old bridge is hardly able to handle.

Only vessels lighter than 300 tons can sail beneath the 5-meter-tall old bridge, restricting water transport along the river, the group said.

Demolition began in May last year with half of the bridge deck remaining open to traffic. Ships were also allowed to sail during the project, it said.

The new bridge, said to be the longest and widest steel box girder bridge in Shanghai, spans 1,573 meters over the river. The bridge was assembled on site with 18 steel and concrete boxes to reduce the effect on traffic and the environment.

The reconstruction project was completed in 13 months, five months ahead of schedule. The main span of the bridge has been increased to 138 meters from 66 meters, while the height was elevated to 7 meters from 5.

The eastern part of the bridge will have been renovated by January 2022 and the new bridge will wholly open by June 2022, the group said.
