    Project Overview and Purpose

    The N.C. Department of Transportation proposes widening N.C. 42 in Johnston County – between N.C. 50 and U.S. 70 Business in Clayton – into a four-lane road divided by a median.

    The project would improve traffic flow, reduce delays during rush hour and accommodate expected growth in traffic.

    Traffic volume studies in 2016 found that many portions of N.C. 42 are operating at or above capacity, and that congestion is occurring at many of the intersections with traffic signals. Turning onto N.C. 42 without signals is becoming more difficult.

    The corridor has a peak of 22,000 vehicles each day, with a forecast of an average of 35,000 vehicles on the roadway by 2040 – a 63 percent increase – on either side of I-40.

    Without improvements, congestion will continue to grow and lead to long delays.

    Project Highlights

    The N.C. Department of Transportation plans to widen N.C. 42 in Johnston County – between N.C. 50 and U.S. 70 Business in Clayton – from two lanes to a four-lane road divided by a median.

    Additionally, work would involve replacing three N.C. 42 bridges that no longer meet today's traffic demands. Those bridges cross Swift Creek, Little Creek and White Oak Creek.

    NCDOT will seek to select a "best fit" route for new right of way that will have the least impact on property owners along the corridor.

    Engineers are drafting a preliminary design and conducting a traffic study. Information on which properties would be affected and how the intersections would be improved will be available before a public meeting in Spring 2018.

    NCDOT is also studying how the project would affect the environment and the community. Because the project will receive federal funding, it will comply with a number of federal laws and regulations, including the National Environmental Policy Act.

    Construction is scheduled to begin in 2022.

    Other Area Projects

    This project is separate from plans underway to widen Interstate 40 from Exit 301 in southeast Raleigh to Exit 312 near Clayton as well as to upgrade the Interstate 40/N.C. 42 interchange. That project also is in the planning and development phase, and NCDOT will closely coordinate both projects.

    Project History

    Since the early 1990s, the N.C. 42 corridor has experienced rapid development following the completion of I-40 through Johnston County and, more recently, the U.S. 70 Bypass in 2008. The region's proximity to Raleigh and Research Triangle Park are fueling the growth, and new industries, businesses and residential subdivisions continue to spread along the corridor.

    The N.C. Department of Transportation first identified the need to widen N.C. 42 between N.C. 50 to Cleveland Road, as well as the section between I-40 to U.S. 70, in a 1996 feasibility study.

    Between 2012 and 2015, the town of Clayton the Capital Area 2040 Metropolitan Transportation Plan and the Johnston County Comprehensive Transportation Plan adopted similar widening proposals for N.C. 42.

    In mid-2016, NCDOT began doing pre-construction planning for the proposed project.

    Resources for Local Property Owners

    Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
