National Highway Construction Cost Index (NHCCI)

This webpage provides 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. The National Highway Construction Cost Index (NHCCI) is intended to replace the Federal Highway Administration's (FHWA) Bid-Price Index (BPI) in the future, but also to be compared with BPI for historical purposes.
