MWAA is currently proposing to use $150 million from the Commonwealth of Virginia to 'buy down' the toll increases for two years, so that a $0.50 hike will take place Jan. 1, 2013, another $0.75 Jan. 1, 2014, and another $1.00 Jan. 1, 2015.
While this lessens the public outrage by making the increase more gradual, it means that the tolls will probably have to increase more rapidly in the future, or MWAA will continue asking for additional taxpayer bailouts. The toll avoidance traffic impact on alternate routes will be 32,000 cars/day diverted onto free roads like Rt. 7 by 2015.
