The document summarizes population growth projections and transportation challenges for the Middle Tennessee region through 2035. It projects that the population of the 10-county region will grow from 1.7 million in 2008 to 2.6 million in 2035, and that congestion will significantly increase in the major cities of Nashville, Gallatin, Lebanon, Murfreesboro, Franklin, and Clarksville unless the regional transportation system is improved. It encourages shaping future transportation plans to accommodate an additional one million residents in the region over the next 25 years in a way that supports economic growth while maintaining environmental and quality of life standards.
