The Road to Prosperity: 21st Century Transportation Infrastructure focuses on the connection between transportation infrastructure and future prosperity in Pennsylvania. We have compiled data and information from a wide array of sources to create a foundation from which transportation professionals, policy makers and business leaders can address this serious problem in search of a long term, comprehensive solution. We believe that the conversation about transportation infrastructure needs to change, to create an environment where solutions can be crafted. It is our hope that this booklet helps take the discussion to a new and more productive level.
