Feiyunjiang Bridge, Road bridge in Ruian, China.

Feiyunjiang Bridge, also called Rui'an Bridge, is a cable-stayed bridge over the Feiyun River, linking Dongshan Subdistrict on the north bank with Feiyun Subdistrict on the south. Its single main pylon rises 162.11 metres above the pile cap and is shaped like a vase; the main span is 470 metres, and the deck is 36.8 metres wide.

Construction of the bridge, first called Feiyunjiang Third Bridge, began on 30 April 2003 as part of the upgrade of National Highway 104 in Zhejiang. Its main tower was topped out in September 2005 and the main span closed in January 2008. It opened to traffic on 13 January 2009 and passed final acceptance in December 2015. On 24 August 2008 the Rui'an place-names committee formally named it Rui'an Bridge.

The bridge was first named Feiyunjiang Third Bridge and officially became Rui'an Bridge on 24 August 2008. Its four Chinese characters were traced from a manuscript by the Qing-dynasty Rui'an scholar Sun Yirang, held at the Yuhai Library.

The bridge carries China National Highway 104 traffic on six lanes, three in each direction, between Dongshan Subdistrict on the north bank and Feiyun Subdistrict on the south bank. It forms a control section of Wenzhou's coastal avenue, so drivers heading along that route cross here.

The bridge's name was cast from rubbings of calligraphy by Qing-dynasty Rui'an scholar Sun Yirang, taken from manuscripts kept at the Yuhai Library. The upper crossbeam of the pylon has three oval holes, a nod to the bridge's former name, Feiyun River Third Bridge.
