Highway as road network connectivity plays an important component in regional development that can overcome inter-regional development gaps. Spatial planning and cost priorities of the highway projects must be considered when examining the optimal highway routes, especially in areas that have varied slope characteristics like in Sukabumi-Cianjur area. Therefore, analysis and modeling are needed to show the choice of effective and efficient highway routes amid environmental condition in the region. Least Cost Path Analysis (LCPA) and Multi-Criteria Decision Analysis (MCDA) can be used to determine the optimal route of a road network. This modeling uses various criteria such as topography, geology, land use, and multi-hazard areas with three MDCA and LCPA simulation models. Based on the suitability of highway development with spatial planning in 2030 using scoring assessment, the optimal highway route from Sukabumi-Cianjur is LCPA-MDCA 1 with total score 69.06 and 49% length of the route that is suitable. Meanwhile LCPA-MDCA 3 shows total score 65.6 with 48,8% length that is suitable, and the least optimal route is LCPA-MDCA 2 with total score 65.48 and 44,6% length of the route that is suitable.
