As the main connecting channel between Zhengzhou Xinzheng International Airport and Zhengzhou City, Zhengzhou-Airport expressway was built in 1994. It starts from the end of Zhongzhou Avenue to the south of Longhai railway and ends at the airport interchange. The total length of the expressway is 26.532km, the design speed is 120km/h, the subgrade width is 26m, and the two-way four-lane highway. Since its completion, the airport expressway has become the most important entrance and exit in the south of Zhengzhou city. With the rapid development of China's economy and the rapid growth of the number of motor vehicles in Zhengzhou, the airport expressway has been unable to meet the needs of Zhengzhou's "South Gate" and southern express channel. Therefore, the provincial and municipal governments decided to quickly start the Zhengzhou airport expressway construction project, namely the airport expressway reconstruction and expansion project. After receiving the entrustment, our company quickly carried out the preliminary investigation and engineering surveying and mapping, and carried out the design on the basis of comprehensively summing up the domestic expressway reconstruction and expansion experience, fully investigating the current situation and its own characteristics of the airport expressway, and put forward the feasible scheme to ensure the normal traffic of the airport expressway during the implementation of the reconstruction and expansion project. The idea of the scheme has won the unanimous praise of the owners and the majority of traffic participants!

After the reconstruction, the subgrade width of the airport expressway is 42m, with two-way eight lanes, which greatly improve the connectivity convenience between the main urban area of Zhengzhou and the airport economy zone.
