Beijing-Hong Kong-Macao Expressway Unicom Avenue Overpass

The combined interchange of Beijing-Hong Kong-Macao Expressway, Provincial Highway 102 and Four-port Linkage Avenue is located in the southwest of Zhengzhou Airport Economic Comprehensive Experimental Zone, on the east side of Beijing-Hong Kong-Macao Expressway, at the intersection of Four-port Linkage Avenue and Provincial Highway 102.

The project adopts the turbine type where Four-port Linkage Avenue and Provincial Highway 102 intersect, the A-type horn on the Beijing-Hong Kong-Macao Expressway side T-shaped interconnection scheme on the side of Four-port Linkage Avenue, and the cross-provincial Highway 102 on Four-port Linkage Avenue.

Four-port Link Avenue is a main road connecting the north and south of Zhengzhou in the eastern part of Zhengzhou City, and it is also one of the 10 urban expressways in Zhengzhou metropolitan area. The construction of the project will adopt advanced fully prefabricated splicing technology, so that the Beijing-Hong Kong-Macao Expressway, Provincial Highway 102, and Four-port Linkage Avenue, the three “traffic arteries” with an investment scale of over 10 billion, are “connected in series” in the form of large-scale interchange projects. The transportation interconnection function of +1+1>3 has become the largest "combined interchange" project in Zhengzhou, realizing the smooth flow of the four-port linkage road in the entire Zhengzhou from north to south.
