The routing of interstate highways in the United States is primarily determined by the Federal Highway Administration (FHWA), which operates under the U.S. Department of Transportation. State transportation agencies also play a significant role in the decision-making process, as they assess local needs and conditions. Planning typically involves collaboration between federal, state, and local officials, with public input and environmental considerations influencing the final routes. Ultimately, the decision is based on a combination of factors including traffic demand, economic benefits, and community impact.
