The Georgia Department of Transportation is responsible for maintaining Interstate 75 and state highways within Henry County. Georgia DOT projects include road widening, intersections, and maintenance work.
In 2015, state lawmakers passed the transportation funding act (TFA). The legislation, also known as house bill 170, raised the state gas tax providing additional funding to advance road projects. Henry County is a major benefactor of HB 170 with about $500 million dollars in state funding budgeted for major projects.
