−	Zangmu Railway Bridge is the showcase bridge structure on the high speed line between Lhasa and Linzhi in mountainous Tibet. The main arch span of 430 meters ~~will rank~~ among the 15 longest arch spans in the world. Among railway-only arch spans, Zangmu will rank fourth only behind the Nujiang, Beipanjiang Qinglong and Xijiang Railway Bridges. Among CFST (Concrete Filled Steel Tubular) bridges, Zangmu is the largest ever used for a railway span. Once the arch is closed, concrete is pumped into the main arch rib tubes from the bottom up. Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the entire structure.	+	Zangmu Yarlung Zangbo Railway Bridge is the showcase bridge structure on the high speed line between Lhasa and Linzhi in mountainous Tibet. The main arch span of 430 meters ranks among the 15 longest arch spans in the world. Among railway-only arch spans, Zangmu will rank fourth only behind the Nujiang, Beipanjiang Qinglong and Xijiang Railway Bridges. Among CFST (Concrete Filled Steel Tubular) bridges, Zangmu is the largest ever used for a railway span. Once the arch is closed, concrete is pumped into the main arch rib tubes from the bottom up. Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the entire structure. Due to the high altitude, the possibility of non-compacting concrete within the arch tubes was rectified by the use of a non-shrinkage mix that would be more stable.
		+
		+	The main span of 430 meters has a 3.84 to 1 rise ratio with truss sections having heights between 7.2 and 13.2 meters. Unique to this concrete filled steel tube bridge, the tubes have diameters that vary between 1.6 and 1.8 meters. This is also the first major arch bridge in China to have only weathered steel with no paint.

	Since the main span of Zangmu is wedged between two steep mountain slopes, the arch sections will be lowered into place via one of the longest span highlines ever used for the construction of a bridge with a distance between cable anchorages of approximately 940 meters. The Yarlung Tsangpo River is the longest and largest waterway in Tibet, eventually feeding into the famous Brahaputra River and is often named the Tsangpo-Brahaputra when referring to the whole 2,900 kilometer long river. The Zangmu Railway Bridge crossing is over a reservoir created from a downstream dam and the height estimate of 90 meters is to the old river level.
