Progress is described on development of methods, techniques, and criteria for constructing roads on glacial ice surfaces and adjacent ice-free terrain. Terrain, weather, ice movement, ice ablation, meltwater flow, performance of road fills, subsurface temperatures, and thaw penetration were studied. Soil properties and physiography of an area about 15 miles square near Camp TUTO were investigated to obtain data on sources of borrow materials and other data needed in de sign of roads, building foundations, etc. Road construction was primarily a continuation of that begun previously, with the objectives of making existing roads more useful and investigating several proposed designs. An 80-ft-long, wooden pile-bent bridge was constructed on the ice by 6 men in 2-12 weeks it supported the heaviest mobile equipment used and performed satisfactorily for 1-12 thaw seasons.
