The Humen Pearl River Bridge (simplified Chinese: 虎门大桥; traditional Chinese: 虎門大橋; pinyin: Hǔmén Dàqiáo; literally: Tiger Gate Huge Bridge or the Grand Tiger Gate Bridge) is a bridge over the Pearl River in Guangdong Province, southern China. It consists of two main spans - a suspension bridge section and a segmental concrete section. It connects the Nansha District of Guangzhou to Humen Town of Dongguan. Completed in 1997, the suspension bridge has a main span of 888 meters, and the segmental concrete section's main span of 270m is one of the longest such spans in the world.

Economic significance

The Humen Bridge across the Bocca Tigris, the mouth of the Pearl River and the strait that separates Shiziyang channel in the north and Lingdingyang channel in the south, is an important link in the expressway network of Guangdong Province in southern China, connecting the Shenzhen and Zhuhai Economic Zones, as well as the rest of the coastal region, with Hong Kong and Macau.

Features

View from the deck of the Humen Pearl River Bridge

The 3618-m-long bridge is divided into five sections: the east approach, the suspension bridge section, the middle approach, the segmental concrete section, and the west approach.

Geological conditions at the bridge site are relatively good, with bedrock overlaid by thin soil layers, although conditions differ on each side of the river. Hurricanes are common occurrences, so the design wind speed at the bridge deck level was established at 61 m/s.
