Not to be confused with Dashengguan Yangtze River Bridge.

The Nanjing Dashengguan Yangtze River Bridge, formerly Third Nanjing Yangtze Bridge, is the first cable-stayed bridge with steel tower stanchions located in Nanjing, China.[1] It is the third crossing of the Yangtze River at Nanjing. The cable-stayed portion is just a part of the 4.7 kilometers of the complete bridge. Constructed in slightly more than two years at a cost of $490 million, this bridge features dual 215 meters towers. The main span measures 648 meters. When it was completed in 2005 it was the third longest cable stayed span in the world.[2] It still ranks among the top 20. The bridge carries the G42 Shanghai–Chengdu Expressway and the G2503 Nanjing Ring Expressway. The bridge has renamed on 20 December 2019.[3]
