The Infrastructure Investment Prioritization Initiative (IIPI) partners with federal, state, and local governments to develop infrastructure policies that create more equitable, resilient, and economically dynamic communities. As an interdisciplinary initiative of the National Academies, the IIPI convenes top experts from the public and private sectors to ensure that America’s infrastructure investments are informed by sound science and engineering. Through activities ranging from interactive workshops to consensus reports and forums, the IIPI works at the intersection of complex transportation, water, energy, and communication issues to develop pragmatic, actionable, and non-partisan options for policymakers and practitioners across the nation.
