317国道是东西走向还是南北走向？英文双语对照

317国道是东西走向的国道。

317国道(或“国道317线”、“G317线”)是中国的一条国道，也称为川藏公路北线，318国道支线，起点为四川成都，到西藏那曲，里程为2030千米，在十三五时期，延长终点为西藏阿里地区噶尔县。

国道317线起于成都，止于那曲，是西藏公路主骨架网“ 三纵两横六通道”中北横线的组成部分。据相关负责人介绍，昌都至那曲段，全程764公里，是川藏公路的备用路。

1951年5月，十八军53师157团等部队开始按照上级的要求，在达马拉山（即达玛拉山）上修筑公路，这条路就是举世闻名的川藏公路的一段。

那时没有现代化的施工机械，只能靠手挖肩扛；工具也很简单，只有钎、镐、筐、扁担、钻等。

川藏公路大大促进了西藏经济的发展和人民生活的改善，改变了西藏长期封闭的状况，对西藏经济建设和国防建设都具有极其重要的作用。

妥昌（妥坝－－昌都）公路全长118公里（最初为121公里），是国道317线即川藏公路北线的一段重要路段，是一条重要的交通运输大动脉和国防公路。

受20世纪50年代初对公路通车要求紧迫和施工条件差等诸多因素制约，该路段纵坡大，坡距长，为事故多发地段，正常行驶需一天时间，雨雪季节，时常发生塌方或积雪，对行车安全带来严重影响。

昌都县妥坝乡到昌都地区驻地，有翻越达马拉山的121公里的盘山公路，需要一天时间而且路途风险大，一直使用了50多年，一直是四川到昌都的一条主干道，也是村民们进出山的必经之路。

然而，随着社会的发展、时代的进步，这条又高又险又难走的路，越来越跟不上发展的需要。

公路改建工程由国家交通部批准建设，路线全长110.94公里，项目投资5.5亿元，建设总工期为3年。工程完工后，经317线国道从昌都至成都的车辆将避开山高路险的达玛拉山。

改建后的妥昌公路除昌都镇2公里的过境公路按二级标准改建外，其余路段按山岭重丘区三级公路标准改建，路基宽度为7.5米，路面宽度为6米，路面结构为沥青砼路面。

改建后的妥昌公路为110.94公里，行车时间可减少三分之二。2002年，全长111公里的妥（坝）昌（都）柏油公路开始修建，2006年竣工并投入使用。

三大改建:“十二五”期间，国道317线路中有三个重点路段需进行改建，主要包括珠角拉山隧道及连接线新建段、斜拉山至巴青段、类乌齐至丁青段。该改建工程计划年内开工，未来将全面改造成黑色化路面。

昌都至类乌齐段，全程105公里，此段路程开始有柏油路；类乌齐至丁青共148公里，从类乌齐出发先缓后急，斜拉山至巴青段，路线所经大部分地区依山傍水，个别路段横坡陡峻，沿线地质灾害较多，特别是丁青前后，地质灾害尤为集中。

自治区交通运输厅相关负责人介绍，昌都地区珠角拉山隧道及连接线新建工程，全长8.842102公里，总投资88640万元。改造后的公路按照三级公路标准建设，路面为沥青混凝土路面，路基宽度7.5米，设计速度30公里/小时。

国道317线斜拉山至巴青段公路改建工程全长103.252公里，按三级公路标准设计，设计行车速度30公里/小时，路基宽度7.5米，采用沥青混凝土路面。

国道317线类乌齐至丁青段公路改建工程全长151.75公里，其中主线长143.65公里，按三级公路标准设计，设计行车速度30公里/小时，全线采用沥青混凝土路面。

“国道317线中这三段重点改造建设路段，计划年内开工建设。

“十二五”期间，国道317线计划改造建设路段共长386公里。这些路段进行改造建设后，未来将全面实现黑色化路面。

国道317线与国道318线路相比，路程将缩短很多，但路况都属于三级公路标准，相差不大。

2019年9月26日，位于西藏自治区昌都市的国道317线珠角拉山隧道通车，将行车路程缩短19.6公里，时间缩短近1小时。珠角拉山隧道及接线工程，是“十三五”时期西藏自治区确定的重点公路交通建设项目之一。隧道长4605米，还有1座长108米的大桥，桥隧按公路二级设计。
