The joint stamp issue by Chinese and Turkish posts is dedicated to famous bridges of the both countries: the Yichang Yangtze Highway Bridge in China and the Bosphorus Bridge in Istanbul, Turkey.
The Yichang Yangtze Highway Bridge is a suspension bridge that crosses the Yangtze River some 20 km downstream from the center city of Yichang, China. The bridge was essentially designed to be extremely similar in appearance to the Golden Gate Bridge in San Francisco, USA. The construction of the bridge started on February 19, 1998 and it was open for traffic on September 19, 2001. It was a main span of 960 meters. As of 2012 m it is among the 30 longest suspension bridges, based on the length of the main span.
The Bosphorus Bridge is one of the two bridges in Istanbul, Turkey, spanning the Bosphorus strait and thus connecting Europe and Asia. It is a gravity anchored suspension bridge with steel towers and inclined hangers. The aerodynamic deck hangs on zigzag steel cables. It is 1,560 long with a deck width of 33.40 m and the total height of the towers 165 m. The Bosphorus Bridge had the 4th longest suspension bridge span in the world when it was completed in 1973, and the longest outside the United States. At present, it is the 19th longest suspension bridge span in the world.
