    Rapid urban development and increasing landuse changes due to increasing population and economic growth is being witnessed of in Ethiopia and other developing countries. The measurement and monitoring of these land use changes are crucial to understand land use cover dynamics over different spatial and temporal time scales for effective land management. Urban sprawl may be defined as the scattering of new development on isolated tracts, separated from other areas by vacant land (Ottensmann, 1977). Geographic Information System and Remote Sensing data were used to analyze the pattern of urbanization. This was done using temporal satellite image of the study area in year 1986 and 1999 and demographic details from central statistics agency of FDRE. This enabled in quantifying the increase in the built-up area for nearly 14 years. The built up also helps to identify the Shannon¡fls entr opy,which is a measure of concentration of dispersion. With intent of identifying the causal factors, this could be modeled and projected for the future decades. This study is aimed at helping scientists, policy makers, engineers, urban planners and ultimately the common man to visualize how towns and cities grow over a period of time based on investigations in the regions around the highway and cities
