The Winter Road — Tibbitt to Contwoyto
Winter Road Joint Venture
In the Northwest Territories and Nunavut, ice roads are critical links to the
south for remote exploration and mine sites and communities. These
industries depend heavily on the winter road for the transportation of
construction equipment, building materials, equipment parts, power
generators, fuel, oil, and most importantly essential survival goods such as
food and fuel for power generation.
In the Northern parts of Canada, where permafrost conditions and the terrain
make a gravel road challenging to build and maintain, a solid roadbed
capable of supporting heavy load haul trucks can be constructed by clearing
a route across the frozen ground and lakes. The Tibbitt to Contwoyto winter
road’s route — a distance of 568km — travels 87% of the way over
frozen lakes.

Nuna Logistics’ Role
Nuna Logistics is responsible for the annual construction, maintenance,
dispatching, and camp catering for the winter road. The success of the
winter road takes a great deal of planning, experience, unique manpower and
cooperation from Mother Nature; given that 87% of the road comprises ice,
sustained cold weather is required.
With the increasing exploration and discovery of diamonds in Canada’s
North, the demand for equipment, fuel, infrastructures, and perisable goods
has increased the number of loads travelling annually over the winter road:
an ongoing process to ensure route efficiency and safety, and cost
control
Ice Profiling (Pioneers)
number of ice profiling teams two - one team north end and one team
south end
equipment includes ice profiler, amphibious Hagglund, snow cats, plows,
and helicopter support
ice profiling crews, working with helicopter, map, test and clear the
initial winter road route
south crew and north crew work toward meeting in mid-route
Construction and Maintenance
variety of specialized equipment: plows, graders, water trucks, dozers,
snow blowers, specialized low ground pressure equipment
Dispatching and Traffic Control
trucks drivers are not allowed to travel the winter road alone,
therefore, three trucks are dispatched from Yellowknife, NWT on an
average of every 20 minutes
heavy and wide loads are dispatched from Yellowknife between mid-night
to 6:00 am to avoid daily commuter traffic
Camp Catering
full camp catering is provided to trucking and mining/explorations
