Roads are key economic pillars for any economy, major low volume roads in Kenya are faced by a major problem of degradation and soil erosion. These roads have become of great environmental concern causing siltation and land degradation. The research is carried out in three counties of western Kenya and North Rift between High, mid and Low altitude areas. The research used purposive sampling to select the study roads and class E and D roads were selected for the study. Metered drop pins were used to estimate soil loss and soil deposition in the study roads, this was achieved by driving the peg into the ground and measuring the height in two weeks interval for a period of three months between November 2013 to March 2014. Side drain cross sectional areas were measured at specified intervals to obtain soil accumulation or soil loss. Soil movement and deposition was analysed and it was observed that a greater change occurred in the months of November and December 2013 with a deposition change of 11.1 cm compared to 8.80cm for the month of January and February 2014. Highest rate of erosion was recorded at -10.1cm in the rainy months and -6.64 cm in dry months. Total soil volume movement in three months was 8309.75 cm3 where Mt. Elgon Sub County exhibited the highest change of 3284 cm3.
