1月18日，位于临洮县连儿湾乡的定临高速簸箕湾隧道出口彩旗招展，鞭炮齐鸣，由中铁七局三分部承建的簸箕湾隧道右线贯通仪式在现场举行。
该项目以高标准、高质量、高效率阶段性胜利，同时也为定临高速的顺利通车奠定了坚实基础。
据了解，簸箕湾隧道右线全长2113m。洞身围岩以黄土、泥岩、泥质砂岩夹层为主，设计均为五级围岩，隧道最大埋深约200m。定西段洞口位于黄土冲沟右侧山坡，黄土滑坡后缘处，临洮端洞口位于凹型山坡坡脚，崩塌堆积体上方，施工安全风险高、难度大，自开工建设以来，经过500个工作日的顽强拼搏，中铁七局三分部及时解决堵点卡点问题，多方合力推进，在确保安全、质量的前提下，实现隧道贯通，为确保全线通车提供了有效保障。
