Detailed explanation-2: -The building of highways leads to direct destruction and removal of existing ecosystems, and the reconfiguration of local landforms. Moreover, expansion of roads has diverse ecological effects on the topography which is signified by both abiotic and biotic components of terrestrial and aquatic ecosystems 2, 3.

Detailed explanation-3: -The three most damaging effects of road construction and management are noise, dust and vibrations. Noise mainly occurs during road construction phases but it can also occur to a lesser degree during maintenance operations. Dust is created during the construction of gravel roads and unbound aggregate layers.
