In recent years, China has made great achievements in expressway construction, which do attract worldwide attention. To enhance expressway¡¯s capacity, safety, environmental-friendliness, landscape view and so on, new concepts like context-sensitive solution and flexibility for highway design have been encouraged here. And Nanjing-Changzhou Expressway (hereinafter, the NingChang Expy) is just designed with such considerations. Flanking theExpy are varied terrains and unique landscapes along with rich humanisticresources. The present paper focuses upon some of the key technologies employed in its design based on the context-sensitive principle, covering such main issues as safe and harmonious alignment, natural protection engineering, flexible and ecologic drainage, unique landscape, human-centered service area design as well as public participation. The solutions we propose here aim to further build the NingChang Expy into a fully-modernized onecharacterized by its great safety, satisfying environmental protection, ecological balance and attractive landscapes for booming tourism, its design believed to be of valuable reference for future projects of the kind.
