The design goal of Longhai Road Viaduct is to connect the West Ring Expressway and the East Beijing-Hong Kong-Macao Expressway. On June 26th, 65438, the east section of Longhai Elevated Main Line Bridge was opened to traffic, which greatly improved the traffic situation in Zhengzhou, but the ramp connecting Beijing, Hong Kong and Macao at the east end was not connected. After obtaining the construction permit from the high-speed management department on September 6 this year, the construction party accelerated the construction speed and successfully completed the docking with the Beijing-Hong Kong-Macao Expressway in 75 days, making it a reality for citizens to get on the expressway along Longhai Road within 15 minutes.
