In logging, the term refers to a short road or ramp which leads down from a haul road or skid road on a steep angle to a bridge, crossing, or streambed. In general engineering, the term refers to construction of a temporary access road (ramp) from a bank above, down into a streambed either by cutting into the solid bank and building the ramp from the soil taken from the cut (cut ramp) or by filling the area between the top of the bank and the streambed with gravel (fill ramp).
