In these though economic times, this chart gives us some hope that there will be time for our next Governor to recongnize the folly of this project and say, 
"Bury it!"

What is RABA?

              Highway program funding levels are tied to estimates of Highway Trust Fund (HTF) receipts made at the
              time of enactment of TEA-21, and these levels are adjusted each year to reflect the latest information on
              HTF receipts.

              Revenue Aligned Budget Authority (RABA) is the annual calculation of this adjustment, and is intended to
              ensure that highway funding is aligned with actual and anticipated revenue to the Highway Account of the
              HTF

              RABA calculation is not driven by policy, but rather is determined by formula.

              In total for FYs 2000-2002, RABA has provided an additional $9 billion in highway funding.

              Due to the recent economic slowdown and current projections of future HTF revenues, we will experience
              in FY 2003, for the first time, a downward adjustment of TEA-21 projected funding levels.

              The following table illustrates the impact of RABA on the Federal-aid highway program
