    Social development and road safety are closely related to the quality and functionality of the road infrastructure, which must meet the appropriate technical requirements. This technical project focuses on addressing the challenges associated with the growth of vehicular flow on the Pillaro road, proposing a comprehensive solution based on the optimization of its geometric design. The main objective is to improve traffic conditions and reduce travel times for tourists using this route, thus contributing to the tourism and economic development of the region. In order to meet this objective, fundamental activities were carried out, such as a topographic survey using a high-precision GNSS system, an exhaustive analysis of vehicular traffic, and soil studies carried out in accordance with current regulations. These analyses were essential to determine the physical and mechanical characteristics of the terrain, crucial elements in the formulation of the design proposal. The optimization proposal includes both the geometric redesign of the road and the structural calculation of the pavement, incorporating these elements in an estimated budget and an execution schedule. A total road length of 4.875 km was established, along with a projected annual average daily traffic (ADAT) of 7805 vehicles/day for a design period of 20 years. This projection allowed the road to be classified as a Class 1 arterial road, in compliance with current regulations. As a result, the soil studies revealed a design CBR of 20.31 percent, qualifying the material as highly suitable for use as subgrade. Based on these results, the optimum thicknesses for the different layers of the road were determined: 7.5 cm for the asphalt layer, 15 cm for the base and 20 cm for the subbase, thus guaranteeing the durability and functionality of the road. In addition, a detailed economic analysis was carried out, estimating an execution budget of $1,467,274.83. This investment is intended to improve connectivity between the communities and the urban area, promoting economic development in the region.
