四川：京昆高速广绵扩容项目黑龙滩特大桥合龙|糖心vlog官网
中新网成都8月1日电 (记者 王鹏)8月1日，由蜀道集团投资建设的京昆高速广元至绵阳段扩容项目(简称广绵扩容项目)全线关键控制性工程——黑龙滩特大桥实现双幅合龙，标志着全线8座连续刚构桥梁全部合龙，为项目2026年通车奠定了坚实基础。
黑龙滩特大桥位于广元市剑阁县普安镇，全长945米，主墩最高超80米，施工精度要求高。大桥地处剑门蜀道风景名胜区与翠云廊自然保护区交汇区域，生态保护压力大。施工过程中，项目团队践行生态优先理念，采用设备“油改电”、设截排水沟、同步植草护坡、建设多级沉淀池等措施，最大限度降低对自然环境的影响。
广绵扩容项目概算总投资291.9亿元，截至目前累计完成投资234.5亿元，控制性工程完成98.99%。项目起于广元市周家河，止于绵阳市魏城镇东南侧，全长123.984公里，双向6车道，设计时速120公里，是国家京昆高速的重要组成部分，承担着四川北上出川的重要交通功能。
该项目建成后将有效缓解京昆高速广绵段通行压力，广元至绵阳车程将由原来的2小时缩短至70分钟，对提升区域交通效率、助推成渝地区双城经济圈建设具有重要意义。(完)
