    The present research proposes a comprehensive operation and maintenance plan for the drainage systems of the high-traffic inter-cantonal roads such us Ambato– Píllaro, Píllaro–Patate, Cevallos–Mocha, Cevallos–Pelileo, Pelileo–Patate, and Ambato–Cevallos in Tungurahua province. This plan includes activities, descriptions, objectives and scope, procedures, frequencies, labor requirements, materials, equipment, tools, units of measurement, verification and approval processes, as well as payment methods for each identified damage. Thus, this manual is designed to serve as a technical support tool for public and private entities, contractors, and inspectors involved in road management. Through the implementation of the operation and maintenance plan, the aim is to enhance the efficient management of public resources and promote the resilience of road infrastructure. As part of this research, the diagnostic phase is critical, involving field inspections of the high-traffic inter-cantonal roads Ambato–Píllaro, Píllaro–Patate, Cevallos– Mocha, Cevallos–Pelileo, Pelileo–Patate, and Ambato–Cevallos in Tungurahua province. Additionally, a technical datasheet is used for each road to assess the condition of existing drainage structures (ditches, culverts, grates, concrete boxes, ramps, among others). This datasheet includes variables such as drainage type, drainage condition, pavement surface condition, presence of obstructions, debris, sediments, stones, scour, siltation, and other relevant factors. The results will highlight the condition of the road drainage systems and the recurring issues due to inadequate maintenance and operation. Furthermore, the percentages of operation and maintenance required for each road are detailed, along with the frequent problems identified in the drainage systems, including siltation, obstruction by vegetation, cracks or fractures, structural deterioration, sediment accumulation, debris, clogged ditches, silted culverts, vehicle ramps blocked by sediment, concrete boxes filled with debris and sediment, and undersized drainage systems in vehicle ramps.
