		+	当纳界河大桥在2016年开通时，它就成为了世界上最高的铁路桥。其桥面距离桥下乌江原始水面高达310米。这座钢拱桥是从贵阳到织金、纳雍铁路上最高的桥。
		+	纳界河大桥跨越的这段乌江，在当地又称为三岔河。乌江是贵州最大最著名的河流，同时也是世界上高桥最多的河。这条单轨铁路上除纳界河大桥外还有许多高桥，最高的是跨越武佐河的梁桥（220米高）。

	The Wu River is known as the Sancha River where the Najiehe Railway Bridge crossing is located. By far the largest and most famous river in Guizhou Province, the Wujiang also has more high bridges across its waters then any other river in the world. The single track railway line has several other high bridges along its route, most notably the giant beam span over the Wuzuohe River.

		+	The all steel arch is unique for having two concrete T-beam balanced cantilever spans on either side with a span configuration of 48.85 and 48 meters on piers 56 meters tall. The smaller spans over the arch are 24.7 meters each while most of the approach spans are 32.7 and 24.7 meters.

	The Najiehe Railway arch pieces were lowered into place using a highline with two towers 120 meters tall with a span of 458 meters. The rail level is at elevation 1229 meters and is approximately 259 meters above the full level of a reservoir formed from a downstream dam and approximately 310 meters to the original level of the Sancha (Wujiang) River.
