NOTES: Expenditure refers to the value of work done on construction projects underway during a given period time, regardless of when work on each individual project was started or when payment was made to the contractors. Runways include pavement and lighting. Other categories such as air freight terminals, air traffic towers, hangars, and other related facilities and structures are included for the air transportation total, but are not included in the monthly state and local estimates.
