A giant new prestressed concrete beam bridge, the Zhuchanghe River bridge crosses an extremely deep, V-shaped valley near Sanbanqiaozhen on the amazing new G60 expressway that connects Guiyang and Kunming in Guizhou province. Unlike most of of China's tall beam bridges where the piers are either closed or split from the bottom to the top, Zhuchanghe has piers that are closed until the halfway point where they transition to the traditional double shaft configuration. The Hutiaohe and Houzihe Bridges in Guzihou province also have this pier design. The Zhuchanghe Bridge plan follows a continuous arc that gives the span the unique distinction of being the world's second highest curving bridge after the Millau Viaduct in France.

这座巨大的预应力混凝土梁桥，朱昌河大桥跨越了贵州省盘县附近的一个极深的V型峡谷，位于连接贵阳和昆明的镇胜高速公路之上。与中国绝大多数的高耸梁桥不同的是，其他桥梁的桥墩多为整体式桥墩或者的双薄壁桥墩，而朱长河大桥的桥墩下半部是整体形式、而上半部分为双薄壁桥墩的形式。贵州省只有在该桥附近的虎跳河大桥也采用这样的设计方式。大桥的平面线形是一个连续的曲线，是的该桥成为了法国米约高桥之后的世界第二高度的设计独特的曲线高桥。
