The Metropolitan Washington Airports Authority, which operates the toll road, said it intends to raise tolls from a total of $3.50 to $4.75. The new rate would be in place through 2022, when further hikes are planned.
The rate on the Dulles Toll Road has not increased since 2013.
The MWAA said the increase in tolls is needed to raise enough revenue to cover operating costs and debt service. Without the increase, projections show revenues would fall short of money needed to fulfill all financial obligations, including funds for the construction of Metro’s Silver Line.
The Washington Post reported that the MWAA board of directors could vote on the plan this summer and implement the new tolls by the fall.
The toll adjustment plan calls for further rate increases beyond 2022, including increases of between $1 and $1.50 every four years until 2043, when rates would top $11.
