Criteria and Data

Each transportation mode developed documentation detailing score results under the Strategic Transportation Investments law. The results are contained in user-friendly spreadsheets with search and sort capabilities. Criteria summary reports defined how the project scores were generated for each mode.

News Releases


The 2016-2025 State Transportation Improvement Program, which identifies projects that will receive funding during that period, is the first 10-year plan developed under the 2013 Strategic Transportation Investments law.

In June 2015, after a nearly two-year process, the North Carolina Board of Transportation approved the 2016-2025 STIP, which includes an additional 478 highway projects and is expected to support about 300,000 jobs. That's 300 more projects (a 273 percent increase) and 126,000 more jobs (a 172 percent increase) than what the old funding formula, which distributed money equally across the state, would have allowed.

This data-driven approach yielded one of the state's most comprehensive STIPs ever, with 1,073 projects in all 100 counties, and across all modes of transportation for 2016-2025.

STIP Amendment

Recognizing the need to increase investment in the state's transportation infrastructure, the General Assembly took steps in the 2015-2017 state budget (House Bill 97) – passed in September 2015 – that will result in an estimated additional $1.6 billion for transportation construction.

Since the 2016-2025 STIP was developed based on the 10-year revenue forecast in August 2014, NCDOT is amending the STIP to account for the additional funding – just over $685 million for projects at the statewide level and more than $500 million for projects at each the regional and division levels.

Following requirements set forth in the Strategic Transportation Investments law and the Strategic Mobility Formula, NCDOT engineers used the same scoring weights and criteria used to develop the current STIP to re-evaluate proposed projects that were not originally funded.

The North Carolina Board of Transportation, in January 2016, approved the list of proposed projects. In addition to 66 non-highway projects, it includes 92 new and 90 accelerated highway projects, such as:

  • Funding all four sections of the final leg of the eastern section of the Winston-Salem Northern Beltway, which is also part of the Future Interstate 74 corridor (only Segment A had been funded) The interchange at U.S. 52 is also funded.
  • Speeding up by one year construction of Segment B of the I-26 Connector in Asheville
  • Accelerating construction by two years on the Mid-Currituck Bridge, a toll bridge in Currituck County

Success Stories

Some examples of the critical connections made possible in the STIP under the Strategic Mobility Formula:

  • Completing the Fayetteville Outer Loop to connect Fort Bragg to the strategic I-95 corridor to enhance mobility options for the military.
  • Expanding U.S. 321 between Lenoir and Hickory to improve this key regional corridor and better connect the northwestern part of the state to Charlotte and I-85.
  • Improving I-85 in Gaston County and removing the bottleneck in southern Rowan County to enhance this important route for travelers between the Triangle, Triad and the Charlotte area, as well as the Greenville-Spartanburg area.
  • Expanding N.C. 211 to the coastal towns of Southport and Oak Island and improve their connection to the U.S. 17 corridor, which will help relieve congestion during the busy tourist season and improve an important evacuation route.

Several important projects did not score high enough for funding on the statewide level, but they did qualify for regional and division evaluation. Because of strong local input, they were successfully funded on the local level. Examples include:

  • Widening N.C. 24/27 in Stanly County to four lanes from the existing four lanes in Albemarle to the Pee Dee River. The project also replaces one of the two bridges that connect Stanly and Montgomery counties. Its regional score was helped, because both the rural planning organization and division gave the project the maximum regional points.
  • Building the Mid-Currituck Bridge between the Currituck County mainland and Corolla addresses local needs by alleviating congestion on U.S. 158 and N.C. 12. The bridge will also connect the Outer Banks to the Hampton Roads region in Virginia. The project was funded due to the successful coordination of both the rural planning organization and the division office.


In May 2014, NCDOT released data for nearly 3,100 projects for highway and non-highway modes (aviation, rail, bicycle and pedestrian, ferry and public transportation) across the state.

Division engineers, along with metropolitan and rural planning organizations, established clear methodologies for collecting public input and determining how to rank potential projects as required by law.

To calculate a final score for each project, NCDOT combined the technical score and the score used to rank the project by the division engineer, MPO or RPO. Those on the statewide level were scored based entirely on data.

NCDOT used these final scores – along with environmental and engineering information and adherence to the new STI rules and federal requirements – to create a draft of the 2016-2025 (STIP), encompassing nearly 1,100 projects.

After the release of the Draft STIP in December 2014, NCDOT hosted nine regional information sessions and one statewide information session between March 17, 2015, and April 23, 2015, to gather public input on the process that produced the Draft STIP. Nearly 160 people participated in these sessions. Feedback was also gathered online.

Based on the public feedback, the North Carolina Board of Transportation approved the Final STIP on June 4, 2015 – the final step in implementing the Strategic Transportation Investments law.
