The transportation industry has increasingly recognized the vital role sustainability serves in promoting and protecting the transportation infrastructure of the nation. Many state Departments of Transportation have correspondingly increased efforts to incorporate concepts of sustainability into the planning, design, and construction phases of projects and congruently adopted sustainability measures into their internal standard policies and procedures. Sustainably constructed highways foster economic development, promote stewardship of the environment, and solicit citizen involvement for an integrated, comprehensive approach to project planning. As part of an effort to understand the extent to which sustainable design and construction principles are being used, this report selects and analyzes three case studies involving previously completed KYTC projects and assesses their commitment to sustainable concepts. Specifically, this report examines the extent to which KYTC utilized sustainable concepts for each case study as described in FHWA’s INVEST rating system. This research effort comprised three components. First, KTC researchers analyzed KYTC’s policies and manuals for project planning, design, and construction and determined the extent to which INVEST criteria and related principles were incorporated into their standard processes. Second, KTC analyzed the individual case studies themselves, to include project plans and other relevant documentation. Finally, KTC conducted interviews with each of the KYTC district offices responsible for managing those previously completed projects and obtained feedback on the INVEST criteria used for each particular project. Following this approach, KTC validated and finalized the assigned scoring ratings for each case study in accordance with the INVEST scoring guidance. In summary, this report describes the sustainable concepts and corresponding INVEST scores for each project, presents a summary of the main findings, and provides recommendations for the way ahead.
