  • When no cost data is submitted for the entire 3 year period, the National Average of the Costs Collected for the current year is used.
  • Blank means no cost data was submitted for the particular year.
  • Bridge construction costs may vary year to year. To minimize this variation, an average unit cost is used as it is a good measure of central tendency.
    • The use of average unit costs has historically been done for calculating the Highway Bridge Program apportionments.
