Since the boulevard was originally the Southeast Freeway portion of the Interstate Highway System, DDOT and FHWA are required to conduct studies under the National Environmental Policy Act (NEPA) of 1969 to understand the environmental impacts of any changes proposed to Southeast Boulevard.

In addition, Section 106 of the National Historic Preservation Act of 1966 requires evaluating a change’s potential effects on cultural resources. This project is legally designated as the Southeast Boulevard and Barney Circle NEPA, Section 106, and Section 4(f) Evaluation Project.
