Highway investments in Brazil have been insufficient to meet demand, and the necessary interventions could not be carried out simultaneously, in view of the limitations in relation to financial resources, managerial problems relating to investments and the complexity of the bidding process and construction of highways. With this, highlights the importance of prioritization among investment options in the sector, and as a general objective of this work, a methodology to aid prioritization between road investment options was proposed. Through a case study with three options, Multicriteria Analysis was applied using the method - Analytic Hierarchy Process - AHP, with an economic, social, logistical and operational approach. The network of criteria adopted has three levels. The options were selected based on the economic and social importance of road links that pass through Minas Gerais, and are represented by stretches of highway (BR-040, BR-116 and BR -381) that comprise three of the main links in the state. Professionals from various fields, divided into five groups (Highway Engineers, Academics, Agencies, and Other Members) were interviewed, with the objective of creating different scenarios, with different points of view. The interviews were divided into two phases. At first, the criteria were judged, and all selected respondents participated. The second phase dealt with the trial of the options, and participated respondents who work in transportation or road engineering. For the mathematical part of the process, were used the Choice Expert software. For judging the criteria, the consistency of 63.6% was obtained.. The social aspects showed the greatest overall weight relative to the goal, 38.9%. For the trial of the options, the consistency was 75,6%. The BR-381 had the highest final score, with almost 50% of priority. Further sensitivity analyzes showed the convergence of the views of different groups of evaluators. Finally, this study was compared with three other studies related to the topic and, given that the matrices obtained did not show intransitivity in any case, it was concluded that the proposed model is valid.
