厉害了!1000公里的北京“大七环”今天合龙了(图)

2016-12-06 19:09:56   长安街知事

“博友们,去首都机场,想走六环,现在堵车吗?”“除了北京六环,还有哪条路能到承德?我在石家庄,在线等!”……在微博上、论坛里,不少网友曾发出过这样的“呼救”。不过这一切都将成为历史。

长安街知事APP昨日从河北省交通厅获悉,起自北京市密云区、终至河北省涿州市的密涿高速公路当天正式贯通。这条呈“C”字型环绕北京城区的高速公路,与周边的7条高速互通,让北京两座机场直接连线,将成为首都东南方向的交通大动脉。

更重要的是,密涿高速的建成,标志着长约1000公里的首都地区环线高速公路替代路线全线贯通——它犹如一条项链,环绕整个北京,将承德、廊坊、固安、张家口、崇礼等节点城市一一串联起来,进一步完善首都地区公路网,推动京津冀地区高速公路形成了新的格局。

起自北京市密云区,终至河北省涿州市,密涿高速公路途经平谷、三河、香河、廊坊、固安,呈“C”字型包围着北京城区,自北向南与京平、京秦、京哈、京津、京沪、京台、廊涿7条高速实现互通。该路线全长约50.2公里,采用双向六车道标准,自2013年6月起开工建设。

长久以来,作为华北地区的交通要地,北京是我国西北部地区物资出海,东北部地区与中南、西南部地区物资交流的重要枢纽之一。同时,河北南部、东部与北部联系,也均需穿过北京。数量庞大的过境车辆对北京造成巨大交通压力的同时,也给首都造成了严重的空气污染。

据测算,2007年北京市的对外及过境交通量年均约50万辆/日,预测到2020年这一数据将达90万辆/日左右,特别是大货车造成的空气污染更为严重,大大增加了空气中PM2.5的含量。而且,北京路网现状以放射线为主,如遇大型国际活动和应急突发事件,没有疏导绕行路线可选。原规划的对外10条普通国道放射线和7条发射线及1条南北纵线国家高速公路,都要通过北京六环路进行调节和疏导,既不便捷又不经济。
