Environmental Impact Assessments (EIAs) play a crucial role in influencing highway design by identifying potential environmental effects. This guides route selection. This incorporates mitigation measures. And it ensures compliance with regulations. This leads to environmentally sensitive highway projects. Here’s how EIAs influence highway design:
EIAs identify potential environmental effects by assessing the potential impacts of the proposed highway on air and water quality, wildlife habitats, wetlands, and other natural resources.
EIAs guide route selection by helping transportation planners choose the route that minimizes environmental impacts. This may involve avoiding sensitive areas, such as wetlands or endangered species habitats.
EIAs incorporate mitigation measures into the highway design to reduce the environmental impacts. This may include constructing wildlife crossings, restoring wetlands, and implementing stormwater management
