The choice of a route location is a detailed activity that involves evaluation of different factors in order to attain optimal location. Roads are major projects and therefore need to be located to ensure seamless connectivity, which should be optimal. The objective of this research study was to perform spatial modeling using GIS analysis and weighting criterions using Analytical Hierarchical Process to come up with suitable site for an optimum road. To attain optimal road route location, satellite image of the study area was acquired and the image processed and reclassified to obtain baseline data of the area including the land use land cover map. A Geodatabase was created to allow integration with GIS analysis. GIS database included Shapefiles of soils, existing roads, towns, rivers, and vegetation, noise and dust surveys. Questionnaires administered to various experts were processed to give weights derived using Analytical Hierarchical Process (AHP). The weights from different criterions gave unique normalized Eigen vectors in each category.
