Shuanghong Iron Bridge in Baoshan City

Chinese Name:保山市芒宽双虹桥
English Name: Shuanghong Iron Bridge in Baoshan City

The Shuanghong Iron Bridge (双虹桥), located in Mangkuan Township (芒宽乡), Longyang District (隆阳区), Baoshan City (保山市), Yunnan Province (云南省), is a historically significant iron chain suspension bridge that spans the Nu River (怒江). Built in 1789 during the Qianlong Era (乾隆年间) of the Qing Dynasty (清朝), this bridge has served as a key crossing point for both locals and travelers for centuries, offering insight into the region’s rich history and cultural exchanges along the Southwest Silk Road (南方丝绸之路).

The bridge remains a major historical landmark and was declared a provincial cultural relics protection unit in 1993 by the Yunnan Provincial People’s Government (云南省人民政府).

History and Construction

Origins

The Shuanghong Iron Bridge was originally named Feiliang Bridge (飞梁桥) or Feiqiao (飞桥) and was built in 1789 by Chen Xiaosheng (陈孝昇), the prefect of Yongchang (永昌), as part of a larger effort to improve travel and trade across the Nu River. The construction was funded through donations and labor from local residents. It was originally constructed as a wooden suspension bridge but was later upgraded to an iron chain suspension bridge due to its importance as a transportation route.

Reconstruction and Military Significance

In 1859, the bridge was destroyed during a period of military conflict. However, it was rebuilt in 1923, during the Republic of China (民国时期), with significant improvements to its structure. The bridge was further rebuilt in 1933 and again in 1942, when it played an important role during the Second Sino-Japanese War.

In 1942, with the Western Yunnan region facing a Japanese invasion, Chinese forces temporarily removed the bridge’s surface and constructed a military defense post on the eastern bank to block the advancing enemy. The bridge was later repaired in 1944, just in time for the Chinese Expeditionary Force (中国远征军) to use it as a major crossing point during their counteroffensive against Japanese forces in Western Yunnan. This helped secure the Gaoligong Mountain region and led to the eventual defeat of the Japanese in Tengchong (腾冲).

Structure and Design

Physical Dimensions

The Shuanghong Iron Bridge spans a total of 162.5 meters across the Nu River, with a width of 2.8 meters. The bridge is divided into two sections: the east span which crosses the main flow of the river, measuring 67 meters and standing 14 meters above the water; and the west span which crosses a side stream, measuring 38 meters and standing 12 meters above the water.

The bridge is a suspension bridge made of iron chains, with 15 iron chains supporting the east span and 12 iron chains supporting the west span. The structure also includes two stone towers (关楼) at either end and a Wind and Rain Pavilion (风雨亭) in the center, offering shelter to travelers crossing the bridge.

Bridge Design Features

The bridge is designed with a combination of stone and iron. The bridge piers are anchored on island reefs in the middle of the river. These stone piers were specifically chosen for their durability and natural positioning, which allowed for minimal interference with the river’s flow.

The East Tower (东关楼) is made of earth and wood, while the remaining towers and pavilions have been reconstructed after damage over the years.

Cultural Significance

The Name and Legend

The Shuanghong Iron Bridge gets its name from its distinctive appearance, resembling two rainbows arching across the Nu River. According to local legend, when the bridge was first completed, two monkeys from the eastern bank crossed the bridge hand in hand before the official ceremony, thus giving rise to the bridge's alternate name, Double Monkey Bridge (双猴桥).

A popular legend surrounding the bridge tells the story of its construction. When workers began constructing the bridge’s piers, they mysteriously disappeared each night. The foreman, unable to find a solution, stayed up one night and witnessed an old woman appearing at the construction site. She revealed a more suitable location for building the bridge, and the workers subsequently moved the construction to this new site. Local lore suggests that this woman was the Dragon King (龙王) of the Nu River.
