Abstract	The overpass at Highway 41 on the Quebec Autoroute at Berthierville will be supported by 39-in, diameter composite end-bearing piles founded on bedrock 270 ft below the ground surface. The imposed loads fromnegative skin friction caused by the consolidation of the marine clay subsoils may reach two-thirds of the design capacity of the pile. To study the phenomenon of negative skin friction, tvro prototype piles were instrumented and a floating test pile installed. The instrumentation included settlement gauges,piezometers, deformation gauges, strain meters, thermocouples and a slope inclinometer tube. The designdetails of the instr umentation are given and their performance discussed.
