the 7th Ring Road

请看例句：

A 1,000-km expressway linking Beijing and nearby cities in Hebei province was completed on Tuesday. As Beijing already has six ring-roads within the city, the public has been calling the new expressway "the 7th Ring Road".
一条长1000公里、连接北京和河北省多个临近北京的城市的高速公路6日贯通。由于北京市内已有六条环路，公众把这条新高速公路称为"七环"。

起自北京市密云区、终至河北省涿州市的密涿高速公路(Miyun-Zhuozhou Expressway)的建成，标志着"北京大外环"(the Great Beijing Outer Ring Road)正式合环。"北京大外环"俗称"七环"(the 7th Ring Road)，是京津冀交通一体化方案(Beijing-Tianjin-Hebei transportation integration plan)的一部分，目的是通过高铁(high-speed rail)和高速公路(expressway, highway)加强北京和邻省之间的联系。

密涿高速的建成能使北京东南部现有的过境交通(transit traffic)，尤其是货运过境交通(transit traffic of cargo trucks)，逐渐转移至北京外围地区(periphery of Beijing)，对于缓解交通拥堵(ease traffic congestion)有重要意义。此外，密涿高速公路还是一条"机场路"。新机场建成后，这条高速将成为沟通北京两座机场间最便捷的道路(become the most convenient way to get between the two airports in Beijing)。
