Why is it important to assess environmental impacts before highway construction?

Assessing environmental impacts before highway construction is crucial because it helps to identify and mitigate any potential damage to ecosystems and communities. Highways can disrupt natural habitats, affect wildlife migration patterns, and lead to pollution of air and water resources. By conducting thorough environmental assessments, planners can implement strategies to minimize negative effects on the environment, such as avoiding sensitive areas or incorporating wildlife crossings. This proactive approach not only preserves biodiversity but also protects the health and well-being of nearby communities that may rely on the surrounding environment for their livelihood and quality of life. Addressing these impacts ahead of time promotes sustainable development and fosters community support for transportation projects.
