Taihu Bridge, Transportation bridge in Wuzhong District, China.

Taihu Bridge is a road crossing over Lake Tai that connects the Xukou region with Xishan Island through three distinct sections. The structure spans 4,308 meters and serves as a major transportation route across the water.

Construction of the Taihu Bridge began on 27 October 1992 and the full crossing opened on 25 October 1994, with the third span joined first on 30 June 1994. Wu County led the project, which cost 115 million yuan, of which 59.84 million came from public donations and 10 million from Xishan residents and island work units. The bridge replaced ferry access to Xishan Island, which had only been linked by ferry to Dongshan from 1983.

The bridge's name was written in 1992 by then Premier Li Peng during a visit to Suzhou. After it opened, leaders including Jiang Zemin and Zhu Rongji came to inspect it, and in September 1996 Singapore's Lee Kuan Yew toured the bridge and Xishan Island. In October 2000, seven pilots flew aircraft through the span of Bridge No. 1 during a world aerobatic competition.

Since 2017 the newer parallel span carries traffic onto Xishan Island while the 1994 bridge handles the return direction, so drivers keep to the marked lanes. The crossing runs from Xukou past Changsha and Yeshan islands to Xishan; the 3.3 km Yuyangshan tunnel feeds the Xukou end. The deck is exposed to wind and rain, and the 2017 bus collision on span 1 shows why care is needed.

In October 2000, seven pilots flew aircraft through the navigation opening of Bridge No. 1 during a world aerobatic competition on Lake Tai, including Hungary's Besenyei and Lithuania's Kairys. The bridge's three sections have different clearances: Bridge No. 2 stands 22.5 metres above the water, while Bridges No. 1 and No. 3 reach 10.5 metres.
