In feasibility study for highway construction, engineers and stakeholders as decision makers attempt to select the optimal scenario as design and construction references in order to have better strategic planning implementation of infrastructure. This stage requires careful consideration involving several multidimensional factors. The purpose of this study was to develop a decision analysis model using the multi-criteria decision analysis method. First, the Delphi method is used as a technique to dig information on several experts in their fields. Then Pairwise Comparison method is used to consider the preference criteria. This research also used CODAS method as a method for decision making calculation. The three methods above are applied in a case study of highway project planning in the Central Java region. The project has three alternative highway routes, each with its own characteristics. The results of the Pairwise Comparison method indicate the preference criteria used on the impact of road construction on the surrounding environment without ignoring safety criteria. What is unique in this study is the selection of land use and the shape of the contours of the earth that are different from previous studies, where these criteria were not used. The final stage of the CODAS method produces alternative calculations that have the most optimal characteristics by considering the criteria formed. The results of this study can be used in the future as a tool for decision makers to have better result in the feasibility study stage of highway construction planning.
