“A soaring box-arch bridge with a record span, clean impressive lines and innovative use of the side spans of the arch and the deck to resist the thrust of the main arch.”
Lupu Bridge, 2008 IABSE Outstanding Structure Award Winner
The Lupu Bridge is a through arch bridge over the Huangpu River in Shanghai, China, connecting the city’s Luwan and Pudong districts. It was envisioned to ease congestion between the rapidly developing areas in southern Puxi, as well as to help cope with the traffic expected for Shanghai World Expo 2010. The main bridge structure is 750m long including the two side spans of 100m each, and a main span of 550 metres (1,804 ft) over the Huangpu River, totalling 3,900m (12,795 ft) including approach spans. Located adjacent to the Shanghai World Expo 2010 site, it was the architectural centerpiece of the expo, forming part of the western boundary of the expo site.
Construction began in October 2000 using a cantilever method and temporary cable-stays. Over 35,000 tonnes of steel were used in construction. The bridge’s arch was joined on October 7, 2002. When the bridge was completed, it became the world’s longest arch bridge, surpassing the then title holder, the New River Gorge Bridge in Fayetteville, West Virginia by 32 metres (105 ft). An inauguration ceremony was held on June 27, 2003, featuring a group of runners, including Yao Ming, who were the first to cross the bridge. The bridge opened to vehicular traffic the next day.
In 2009, Lupu Bridge lost its title of the world’s longest arch bridge to the Chaotianmen Bridge in Chongqing. The longest span of the Chaotianmen Bridge was only 2 metres (7 ft) longer, at 552 metres (1,811 ft).
