National Highway Construction Cost Index
Construction costs affect the amount that governments invest in new roads, highways, and bridges. These costs depend on the prices of many inputs, including materials like steel and asphalt, labor costs, and overhead costs. This page discusses construction costs for transportation modes for which data are available.
As measured by the National Highway Construction Cost Index, highway construction costs increased at a faster rate from the first quarter of 2017 to the last quarter of 2018, at 2.2 percent per quarter, than all previous quarters since 2009 when highway construction costs first began to rise after a period of decline.
Highway construction costs
The National Highway Cost Construction Index (NHCCI), produced by the U.S. Department of Transportation’s Federal Highway Administration, measures the average change over time in the prices paid by State transportation departments for roadway construction materials and services over time. It can be used to track price changes in highway construction.
