23731

Analysis

NAICS 23731 is the 2022 NAICS industry for highway, street, and bridge construction, part of 2373 (Highway, Street, and Bridge Construction).

It has only one more detailed code, 237310, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 9,256 US establishments in this code in 2023, employing 314,940 people at an average annual payroll of $98,566 per employee (83rd percentile of national industries). 36% of the establishments have fewer than five employees, which is close to the national mix.

Between 2018 and 2023 the number of establishments fell 4% and employment rose 5%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
