The Chushul Chakzam (Tibetan: ཆུ་ཤུལ་ལྕགས་ཟམ), or simply Chakzam which literally means "iron bridge" in Standard Tibetan, was a suspension bridge that spanned the Yarlung Tsangpo river in modern-day Qüxü County near Lhasa, Tibet.

[5] By the 1860s, the bridge was in a state of disrepair that a ferry was in operation slightly upstream offering safer passage.

[1] By 1904, the river had overflown the north bank leaving the northern bridgehead on an island, thus rendering the bridge functionally ineffective.

[7] During the Qing expedition to Tibet of 1910, the 13th Dalai Lama decided to seek refuge in India.

His general Tsarong fought a skirmish against the Chinese here, holding their advances allowing the Dalai Lama to safely arrive in India.
