Ice road construction has concluded the layout of both roads to the drilling sites D1 and D2. Distance signs and marker poles of bamboo have been frozen in place every 250 meters. Work has progressed every day during daylight hours, despite the frigid temperatures which often drop below -30 C, not considering the windchill factor. Both D1 and D2 ice platforms have been marked out, also with bamboo poles, and are awaiting snow clearing prior to the commencement of flooding.
