The Consumer Price Index (CPI) measures the changes in the cost of purchasing products and services. The CPI is computed by the Bureau of Labor Statistics. The higher the number, the faster the product or service rises in price over time. FHWA has developed an approach to generating a construction cost index, entitled the National Highway Construction Cost Index (NHCCI). The NHCCI is intended as a cost index that can be used to assess the purchasing power of the dollar.
Data Source: US Department of Transportation, Federal Highway Administration, Office of Highway Policy Information. The Consumer Price Index is compiled by the Bureau of Labor Statistics and is based upon a 2003 Base of 100.
