Table showing actual apportionments of federal-aid highway contract authority to states for fiscal year 2017 via FHWA Notice 4510.807 (September 30, 2016), compared to the state totals that were estimated in December 15 when the FAST Act was written and then sent out as preliminary totals in Notice 4510.806 on June 30, 2016.

The difference is that, during the recalculation of motor fuel tax receipts attributable to states in August, FHWA realized that Texas needed an extra $238.6 million to reach its 95 percent motor fuel tax payment threshold under 23 U.S.C. §104(c)(1)(B). So every other state’s apportionment had to be reduced by 0.65 percent to get Texas up to the 95 percent motor fuel tax payment minimum for 2017.
