What is the name of the expressway in front of Heishan Lake?

The expressway in front of Heishan Lake is called G30 Lianhuo Expressway Heishan Lake Toll Station. As an important passage in and out of Jiayuguan, Heishan Lake Toll Station of Jiayuguan G30 Lianhuo Expressway has always had a large traffic volume. In order to alleviate the congestion and slow down the speed, a few days ago, the project of adding an entrance weighing detection lane to Heishanhu Toll Station of Jiayuguan G30 Lianhuo Expressway officially started. Approved by the Provincial Department of Transportation, the project plans to invest 979,000 yuan and is expected to be completed in mid-May. After the completion of the project, there will be two truck weighing and charging outlets, which will further improve the capacity of trucks at the entrance of Heishan Lake toll station and the efficiency of weighing and testing, and effectively alleviate the congestion of trucks at toll stations and national highways.
