The original crossing of the Niulan River was part of the 2-lane Zhaodai highway that was completed in 2008. Several years later an upgrade turned the older highway into the southbound lanes of a fully divided part of the 4-lane G85 expressway that goes from Kunming, Yunnan in the south to Chongqing city in the north. The Niulanjiang River flows northwest until it empties into the famous Yangtze River on the border of Sichuan province.

The older crossing is approximately 15 meters lower then its 2016 counterpart. The main span is also smaller at 170 meters versus 190 meters on the Northbound structure.

Breaking with the traditional twin tower piers of most Chinese beam bridges, each of the two main piers of the Niu Lan rise as one solid, continuous box. One end of the bridge terminates into a tunnel.

The upgraded G85 expressway includes several other high beam bridges north of Zhaotong including the 209 meter high Xiongjiagou Bridge.

位于中国云南东北部地区,牛栏江流向北方直到在四川省边境处汇入长江。作为从昆明到昭通的新建2车道高速公路上的最高的桥梁,高耸的牛栏江混凝土梁桥,在昆明以北大概150英里(241公里)处的V型河谷之上跨越了165米。

和中国绝大多数梁桥拥有传统的一组高耸桥墩,牛栏江大桥的两个主墩都是连接着一个实心的连续箱梁。大桥的一端与隧道直接相连。

牛栏江大桥是中国西部省份云南在2003年至2009年之间建成通车的四座特大连续刚构桥之一。其他三座在高度上也类似,但仅有红河大桥是四车道。
