Tundra roads and ice roads supported on water or unfrozen soil are a viable means of transporting module loads across remote northern areas. Module loads to 2,000 tonnes have been transported in recent years on Tundra and ice roads in northern areas and loads to 10,000 tonnes and more have been transported on constructed unfrozen roads in temperate areas.

Design parameters for Tundra and ice roads supported on unfrozen soil or water are presented in this paper for loads up to 10,000 tonnes. Typically the modules would be transported to the northern project area on ocean barges, off-loaded to the shoreline with a temporary or permanent wharf and then transported inland to a facility by the shortest, most direct route available. The crossing of rivers and areas of unfrozen soil presents challenges to the transportation effort and the road design must ensure that sufficient bearing support and traction are available for the module transportation equipment.

Development of Self Propelled Module Transporters (SPMT), especially in the last 10 years, has produced reliable hydraulic lifting and transporting equipment that can readily move module loads to 10,000 tonnes and more. The safe and reliable operation of heavy load SPMT equipment in the north is primarily limited by the ability to construct suitable roads and off-loading structures.
