Highways and expressways have now become major transport corridors worldwide that are contributing to the high level of mobility, communication and connectivity to commercial capitals that are characteristic features of modern technological civilization. At the same time, the pervasive spread of vast network of roads through different environments have established impacts on the natural environment. A long history of radical changes in the landscape and ecological setting have been associated with the road network (Oxley et al., 1974; Kelcey, 1975; Case, 1978; Adams & Geis,1981; Mader, 1984; Bennet, 1990; Reid and Bowles, 1997). A vast amount of documented information on the impacts of road on the wildlife conservation values (Joselyn, 1969; Way, 1970; Zande et al., 1980; Leedy and Adam, 1982; Curatolo, 1986; Anon., 1997) emphasises the fact that these impacts are too important to be neglected in the developmental planning.
