Environmental Study

The National Environmental Policy Act (NEPA) requires that the significance of a project’s environmental impact be evaluated. TxDOT is conducting an Environmental Assessment on the North and South projects, and an Environmental Impact Statement on the Central project.

Each project is undergoing rigorous environmental study, which evaluates impacts to the human and natural environment, including but not limited to, traffic noise, the community, natural resources, cultural resources and hazardous material sites.
