This PhD looks at transportation as a key to Nepal. Geopolitical fluctuations have been determinant in the historical processes of openness and closure that have built superimposed networks. The relations between transport networks (specially roads works) and development are complex and may be analyzed as an on going process. The new concept of syncrasy is part of the demonstration. Nepal is now reliant on a complex roads network. A geographical analysis at different scales reveals many fragmentations in a territory structured by longitudinal valleys. In addition to a new system, organized around multiple centers and peripheries and subject to complex centrifugal and centripetal forces, great flexibility and adaptability seem to be the main factors to take into account. Thus, can Nepal's transportation infrastructure be considered as typical mountain network ?
