Nuomi Bridge
Nuomi Bridge, alternatively the Nuomishih Bridge or the Beigangxi Stone Bridge, is a masonry arch bridge in Guoxing, Nantou County, Taiwan. Completed in 1940, the bridge spans the Beigang River, one of the headwaters of the Dadu River, near Beigang Village. The bridge is known for its use of sticky rice mortar and is a protected monument in Nantou County.
History
Before the Nuomi Bridge was built, a simple wooden bridge existed near the site. During Japan's rule over Taiwan, the Imperial Japanese Army Air Service wished to shorten the transportation time between its two airfields in Tōsei and Hori, so a road was built transversing through the mountainous terrain. The Japanese chose to replace the wooden bridge with a masonry bridge, and as a part of the military's infrastructure, special care was taken with the quality of the construction. Since the bridge was located in an isolated area, local laborers and materials were used: the stone was taken from the nearby hills southwest of Beigang Village, while the mortar was created using a traditional method by combining lime, glutinous rice, and brown sugar. Construction was completed in 1940, and after its completion, the bridge became an important transportation link in the region.Nuomi Bridge once carried Provincial Highway 21 until 1987, when a new bridge for cars was built immediately downstream to the west. In 1994, the bridge was protected as a county-level monument for its historic value. However, the new bridge restricted the river's streamflow, which resulted in a flood during Typhoon Mindulle in 2004 destroying the bridge's deck. A new deck was completed 2008, only to be destroyed again during Typhoon Morakot in 2009. Therefore, the downstream bridge was rebuilt in 2014, this time with consideration to streamflow, and Nuomi Bridge was repaired and reopened to the public in 2019.
