The completion of Binhai Bridge marks the completion of the southern section of Tianjin-Tangshan Expressway. In the past, driving from Jiangsu, Shandong, Hebei and other provinces to Tanggu or to the northeast required taking the Beijing-Fuzhou Expressway, passing through the outer ring road to Tianjin, and then taking the Jintang Highway, which took a big detour. Now, from Hebei Province to Tianjin, the southern section of Jintang Expressway can directly reach Binhai New Area and the core area of Northeast China. At the same time, it is more convenient to drive from Tianjin Port and Binhai New Area to Hebei and Shandong. This will have a far-reaching impact on accelerating the economic development around Bohai Sea and improving the investment environment in coastal areas.
