The purpose of sandbags in front of abutments on the highway is primarily **to increase the overall mass of the highway structure**. By adding weight, sandbags can help stabilize the abutments and prevent erosion or shifting, especially in areas prone to flooding or erosion from water flow. They can also help provide additional resistance against forces that might otherwise jeopardize the integrity of the abutment or roadway.
