The highway construction inevitably may cause certain influence to the cultural heritage and the natural environment along the route, particularly in design stage; if the route selection is unreasonable, it will certainly impact the natural resource seriously along the route. On the contrary, good design can reasonably develop, use, protect and promote the value of cultural heritage and natural environment. Changsha to Jishou (Chang-Ji) freeway is one section of Changsha to Chongqing freeway, which is one of the eight big west channels as planned in China; two cities of Changde and Huaihua and one autonomous region of Xianxi in western Hunan province, along which the cultural heritage and the natural resource are rich, and the natural landscape is exquisite. This paper investigates and analyzes the natural resources along the route of Chang-Ji freeway, puts forward some protection design evaluation indexes for mountain area freeway by the thought of context sensitive design. At last, the paper introduces the effect of applying the indexes to select route of Chang-Ji freeway. 展开更多
