NASHVILLE (AP) — Republican Gov. Bill Haslam on Wednesday proposed Tennessee's first gas tax hike in 27 years to fund an ambitious roadbuilding program that would carry through well after he leaves office in two years. Haslam's plan would generate about $278 million per year in new transportation funding, while at the same time cutting about $270 million in taxes for shoppers buying groceries, manufacturing companies investing in the state, and people earning income from stocks and bonds.
