This study examines the increasing risk of soil erosion to the national road that runs through Barangay II, Maddarulug Sur, and Maddarulug Norte in Enrile, Cagayan. The erosion is slowly weakening the road's structure, which causes damage, dangerous conditions, and expensive maintenance cycles that make it hard for people to get around and hurt the economy. This study utilized a Graphic Information System (GIS)-based methodology to pinpoint the most critical intervention areas, incorporating the Revised Universal Soil Loss Equation (RUSLE) alongside spatial data regarding rainfall, soil type, slope, and land cover. This model created an Annual Soil Loss map that showed a wide range of erosion susceptibility, with values ranging from 0 to 27.67 kg/ha/yr. Land use, slope, and rainfall distribution had a big effect on these values. The erosion susceptibility model shows that the road segments that are most likely to erode are the ones with steep slopes, little vegetation, and are close to the Cagayan River, where water runoff and gravitational pulls are strongest. These results give us a scientifically sound and easy-to-understand map for figuring out which mitigation efforts should come first. The study thus suggests targeted, site-specific strategies such as slope stabilization, reforestation, and enhanced drainage in the susceptible areas. This proactive, evidence-based approach is necessary to protect the service life of this important transportation route and keep the people who use it safe and connected.
