国家高速公路网银(川)百(色)线湫坡头(陕甘界)至旬邑高速公路今天开工

2017-09-28 16:07:50   

央广网西安9月28日消息(记者刘涛)28日,陕西省交通厅召开新闻发布会,宣布国家高速公路网银(川)百(色)线(G69)湫坡头(陕甘界)至旬邑高速公路今天开工建设,陕甘宁革命老区交通基础设施进一步完善。

陕西省交通厅新闻发言人、副厅长薛生高介绍,湫坡头(陕甘界)至旬邑高速公路是国家高速公路网银(川)百(色)线(G69)的组成部分,也是陕西省“2367”高速公路网规划的重要路段。项目路线起点位于陕甘交界支党河特大桥北侧,接甘肃省拟建的银(川)百(色)国家高速公路甘肃段,经陕西省咸阳市旬邑县湫坡头、北崖头、坪坊、南宫4镇(村),止于旬邑县赤道乡西南,接已建成的银百高速公路旬邑至咸阳段。

该路线全长24.878公里(其中甘肃境内0.606公里)。全线采用双向四车道高速公路标准,其中,起点至主线收费站约7.573公里,设计速度80公里/小时,路基整体式宽度25.5米;主线收费站至终点约17.305公里,设计速度100公里/小时,路基整体式宽度26米。桥涵设计汽车荷载等级为公路Ⅰ级。全线设置湫坡头、赤道互通式立交2处,陕甘界省界主线收费站、匝道收费站各1处,旬邑服务区1处。概算总投资25.2亿元,建设工期4年。

薛生高表示,截至目前,湫坡头(陕甘界)至旬邑高速公路项目工可研、初步设计已经批复,该项目工程建设采用设计施工总承包模式建设,设计及施工招标工作已经完成,已经具备开工条件。该项目由陕西省交通建设集团公司负责建设管理,咸阳市人民政府负责该项目的征地拆迁和环境保障工作。

由于湫坡头(陕甘界)至旬邑高速公路位于黄土沟壑地区,地势总体北高南低,区内不良地质主要为黄土滑坡、崩塌及湿陷性黄土。本项目控制性工程是支党河特大桥和梁渠沟大桥,其中支党河特大桥全长1756米,最大桥高181米,最大墩高170米,主桥跨径为85+4*160+85米;梁渠沟大桥主桥跨径为75+2*140+75,采用波型钢腹板预应力混凝土连续刚构建设,在全国同类型大跨径桥梁中位居前列。

薛生高表示,该项目地处陕甘宁革命老区,人文景观、旅游、煤炭资源丰富,发展潜力巨大。但受地形条件限制,沿线经济发展相对滞后,急需加强交通基础设施建设,加快区域扶贫开发。湫坡头(陕甘界)至旬邑高速公路的开工建设,是陕西交通运输系统以实际行动,贯彻落实“五新”战略、奋力追赶超越的具体实践。湫坡头(陕甘界)至旬邑高速公路建设项目的实施,对于深入贯彻实施西部大开发和“一带一路”倡议,完善国家和区域高速公路网,改善区域交通条件,促进沿线优势资源开发,促进陕甘两省经济社会交流和六盘山集中连片贫困地区脱贫攻坚,加快陕甘宁革命老区经济社会协调发展等具有重要的现实意义。
