Project 1, Approach Roads, Greenland R and D Program, was organized in 1954 to develop methods, techniques and criteria for constructing roads on both glacial ice surfaces and adjacent ice-free terrain. This report covers activities for the years 1958 and 1959, which consisted of construction of additional roads and culverts and an annual assessment of the performance of the various roads and other structures on the ice cap. Special measurements were made of ice surface movement, subsurface temperature and melt-water runoff. (Author).
