The assessment will examine potential impacts on local neighborhoods, infrastructure, and wildlife habitats along the proposed route. Advocates argue the line could ease congestion and improve transit access, while critics highlight concerns over construction delays and costs. The review process marks a key step before final approval, with stakeholders awaiting details on how the project may proceed.
