History

The Yangluo Bridge was the fourth bridge constructed over the Yangtze in

. The first was the Wuhan Yangtze River Bridge, known locally as the ''First Bridge'', built in 1957. This remained the only land link across the river for the next four decades and it became increasingly congested as the city grew. To alleviate the crowding on the bridge and promote further development in the city, Wuhan's government began an ambitious program in the early 1990s to upgrade the city's infrastructure by building new bridges and expressways around the city.

The bridge's deck is made of prefabricated concrete sections with an epoxy asphalt roadbed. It includes a 3-metre (9.8 ft) thick steel brace structure with girders at 14 metre intervals under the main deck to stiffen the bridge against the wind. The two main cables that support the deck are in diameter and each consists of 19,558 5.35 mm steel wires arranged in 154 strands. The portion of the cables over the shorter northern approach span include an additional eight strands to withstand the greater force exerted on them because of the smaller ratio in relation to the length of the main span. The north and south support towers for the main cables are and tall respectively and constructed of
