NASHVILLE, TN (WRCB) -- Governor Bill Haslam and the Tennessee Department of Transportation released a three year transportation plan.

The program features approximately $1.5 billion in infrastructure investments for 80 project phases in 47 counties as well as 15 statewide programs.

Tennessee is one of only five states that do not borrow money to fund transportation projects, and the program continues TDOT's "pay as you go" philosophy, carrying no debt for any transportation initiatives.

Among the projects funded are improvements to the interstates, addition of truck climbing lanes, interchange projects and  the construction of a three-mile stretch of Interstate 69.

Multiple widening projects are planned for Hamilton County including US 27, Apison Pike and East Brainerd Road.

The program includes projects to expand TDOT's Intelligent Transportation System, adding cameras and Dynamic Message Signs on I-24 over Monteagle Mountain and on I-65 north and south of Nashville.

The program includes dedicated funding for 15 transportation programs including Rockfall Mitigation, Spot Safety Improvement, the statewide HELP Program and new initiative to enhance connections between modes, such as sidewalks and park-and-ride facilities at key locations along state routes.
