Abstract: Since the mid-1990s, each province of China has acted on its own free will in expressway planning and construction, which results in some serious problems for regional sustainable development and land planning. In this paper, we analyzed the scale and spatial network of expressway planning and compared the national network with provincial network of expressway. The result shows that the scale of expressway network in the long-term period will reach 17.4 × 104 km and form a dense expressway network like the cobweb. The expressway planning of provinces in the central and western China expands greatly from the initial scale. Moreover, we discussed the spatial influences of the gigantic expressway planning network with indices of accessibility, service capacity and spatial partition. The results demonstrate that the scale of planned expressway network by each province is too large and many new planned routes chiefly link small towns and the backland areas. The planned provincial expressway network deviates from the spatial distribution of China's economic development, population and city system. Particularly, the planned scale and spatial cover capacity of expressway network deviates from its economic and technologic attributes. Finally, we revealed the development mechanism on the regulation of each province's expressway planning and expansion of the expressway planning scale. The discussion result shows that the planning system of expressway, finance system for construction, charge policy, strategies to the financial crisis in 2008 and the criterion for assessing political achievement lead to the regulation of expressway planning and the enlargement of each province's planning scale.
