Discussion on Reconstruction and Extension Scheme of Wuhan North Trumpet-shaped Interchange in Beijing - Hongkong - Macao Expressway

The trumpet-shaped interchange is the basic interchange with the highest application ratio in China. Its reconstruction and extension is very difficult because of every factor restriction. The existing projects are fully applied in the reconstruction and extension of Wuhan North Trumpet-shaped Interchange in Beijing - Hongkong - Macao Expressway. The congestion points of the interchange are solved by upgrading the original site as the interchange functions. The main line of Wuhan North Interchange, the reconstruction and extension of G107, and the long-term traffic flow and land use, and the other control factors are analyzed and introduced. The design ideas and specific schemes for the double-trumpet interchange are discussed according to the actual control factors and functional requirements.
