On-site transportation is achieved by means of road. The materials and equipment transported to the side through external transportation will be stored into corresponding warehouses, so as to regulate the construction needs and realize guaranteed supply and not to delay in program. There is already a village road connecting the dam with the powerhouse, with the width of 6m, which is a clay-bound-macadam road and most sites are near the road. In this project it is necessary to build a 0.7km temporary road.
