The Yangtze River Crossing may refer to one of three overhead power lines crossing the Yangtze Rivermarker in the People's Republic of Chinamarker.

Jiangyin

One exists at Jiangyinmarker, Jiangsu Provincemarker, Chinamarker. Pylons situated at and at . It is a section of the 500kV-power line from the Yan Cheng power station to the Dou Shan substation in the province of Jiangsumarker. The power line section running over the river has a span width of . It is carried by two tall suspension electricity pylons, each weighing 4,192 tons, and as of April 13, 2004, both are the tallest electricity pylons in the world. The towers even surpass the height of the Eiffel Towermarker, which is (including antenna) in comparison. They are identical lattice towers of square cross section with an area of × 68 m at the base and × 8 m at the top. The pylons are of the Danube type carrying 4 conductors on the lower crossbar, above ground with a length of and two conductors on the upper crossbar. The insulator chains are long. These pylons are both equipped with an elevator which runs in a cylindrical tube in its center, and a spiral staircase circles the elevator shaft outside.

On each side of the river are each main span pylon, followed by two anchor tower; one for each circuit. They anchor pylons are each tall, weigh 110 tons and stand on an area of × .

Construction of the pylons started on November 8, 2002. They were completed on April 13, 2004. On November 18, 2004, the power line went into service.

Nanjing

A dual circuit, 500 kV AC overhead powerline crosses the Yangtze River at Nanjingmarker, Jiangsu Provincemarker, Chinamarker, built in 1992. It uses two tall pylons built of reinforced concrete, which may be the tallest pylons built out of concrete in the world. They are situated at and at and carry 6 conductors in two levels. The span width is .

Wuhu

The HVDC Three Gorges-Changzhou powerline crosses the Yangtze River near Wuhu, Anhui Provincemarker, Chinamarker, at and . The pylons were built in 2003. The crossing consists of two tall pylons built as constructions of tubular steel, which carry two conductors. The span width is . Close to it, there is a 500 kV AC powerline crossing with a span width of on probably taller towers and a 110 kV AC powerline crossing with a span width of . Both AC crossings have 6 conductors.
