青海花石峡至久治高速公路是西北地区第一条绿色循环低碳公路,平均海拔4000米以上,高原高寒条件下施工难度极大。银河总站官网二公局承建4个标段约30公里施工任务,其中久治三号隧道是大武至久治段海拔最高、洞身最长的隧道。

Qinghai Huashixia-Jiuzhi Expressway is the first green low-carbon highway in northwest China, with an average elevation of more than 4000m. It is very difficult to construct under the condition of alpine plateau. CCCC Second Highway Engineering Co., Ltd. undertook 4 sections, including about 30km, and Jiuzhi No.3 Tunnel is the longest tunnel in Dawu-Jiuzhi section, with the highest elevation.
