		+	The Iron Lock Bridge is located at the foot of Ziyun Mountain. It was built in the Ming Dynasty. It has a wooden roof, and iron locks are installed at both ends of the bridge. "The night lock is guarded to separate the spies". In the 21st year of Guangxu in the Qing Dynasty (1895), the Iron Lock Bridge was rebuilt, with a net span of 18 meters, a width of 4 meters, a total length of 20 meters, and a height of 110 meters from the bridge to the bottom of the river. By 1970, it had become a dangerous bridge. The County Transportation Bureau allocated 12,000 yuan to build a stone arch bridge on the original site, with a net span of 28 meters.

−	Historically, the Tiesuo Bridge might be the most important high bridge in all of China. Originally built around 1704 AD as a chain bridge during the Wanli era, it was the first bridge in the world to exceed the Ponte Delle Torri in Spoleto, Italy at 85 meters in height. Tiesuo remained the world's highest bridge for almost a ~~decade~~ until 1793 when the Puente Nueveo Bridge was completed in Ronda, Spain. Wrapping itself around the small peaks that line the Loushui River, the ancient route was one of the only northern access points into the city of Hefeng in Hubei Province.	+	Historically, the Tiesuo Bridge might be the most important high bridge in all of China.

	Although it was probably rebuilt several times since the 1700s, the first recorded rebuild of the chain bridge was in 1895. This may have also been the first time that steel was used in the chains. Then in 1970, the chain bridge was replaced with a 28 meter span stone arch that is 4.5 meters wide and was situated approximately 7 meters above the chain bridge crossing. Finally in 2018 a larger and wider concrete arch was built 10 meters above the 1970 span and exactly 100 meters above the reservoir water. The local road was also widened to handle two lanes of traffic and a visitors center and restaurant are now part of a new tourist area with parking.
