今年9月,我国大陆兴建最早的高速公路——沈大公路全线通车。这条高速公路将辽东半岛工业城市群与沿海地区更加紧密地连在了一起。有了它,辽东半岛的对外开放就象飞机有了跑道,从此可以振翅高飞。 在这条高速公路的两端,分别是辽宁省最大的工业城市沈阳和大连,中间还有一个营口。这三个城市分别拥有辽宁省仅有的三个对外开放示范区,人口 In September this year, the earliest expressway in our country was built - the opening of Shen-Da Highway opened to traffic. This highway connects the Liaodong Peninsula industrial city cluster and the coastal areas more closely together. With it, the opening of the Liaodong Peninsula is like an airplane with a runway, from which you can fly high. At both ends of this highway are Shenyang and Dalian, the largest industrial cities in Liaoning Province, with Yingkou in the middle. These three cities each have the only three demonstration zones and population in Liaoning Province
