The main purpose of this legislation, known as the Interactive Federal Review Act, is to enhance the environmental review process for highway projects. It aims to achieve this by promoting the use of modern technology, specifically interactive digital platforms and digital twins, which are detailed 3D models of project elements. The goal is to make the review process faster and more engaging for the public. Key provisions of the Act include the requirement for the Secretary of Transportation to encourage the use of these digital tools in environmental reviews.
