Passed in 2013, the Strategic Transportation Investments law allows the N.C. Department of Transportation to use its funding more efficiently and effectively to enhance North Carolina’s infrastructure while supporting economic growth, job creation and a higher quality of life.
This process encourages thinking from a statewide and regional perspective while also providing flexibility to address local needs.
The STI law also establishes the Strategic Mobility Formula, which allocates available revenues based on data-driven scoring and local input. It is used to develop NCDOT's State Transportation Improvement Program, which identifies the transportation projects that will receive funding during a 10-year period.
Federal law requires the State Transportation Improvement Program to be updated at least every four years. NCDOT, however, updates it every two years.
Work is currently underway to update the STIP for 2020-2029.
