After a brief mention of the principles of design applied to theconstruction of the lamosangu-jiri road in the central region of nepal, the authors describe the effort undertaken to rehabilitate a road section heavily affected by a flood in the early monsoon season of 1987. Innovative techniques for the construction and maintenance of roads in the himalayan region, such as anchoring, drilled subsurface drains, and flexible river protection, were introduced. In view of design options for low-volume roads in hilly terrain, practical suggestions such as low initial investment and event-related rehabilitation are discussed. This paper appears in transportation research record no. 1291, Fifth international conference on low-volume roads, may 19-23, 1991, raleigh, north carolina, volume 2.
