    Metadata Updated: January 6, 2026

    The National Highway Construction Cost Index (NHCCI) is a price index that can be used both to track price changes associated with highway construction costs, and to convert current dollar expenditures on highway construction to real or constant dollar expenditures. This dataset contains the quarterly NHCCI estimates as well as the Seasonally Adjusted NHCCI and Component Contributions to Changes in NHCCI.
