Airport board advances plan to increase Dulles tolls

The Washington region’s airports board on Wednesday advanced plans to increase tolls on the Dulles Toll Road to help pay for the construction of the $6 billion Silver Line.

Metropolitan Washington Airports Authority board members are considering raising tolls from the current $2.25 to $2.75 in 2013, $3.50 in 2014 and $4.50 in 2015. The board will make a final decision on the scheduled toll increases in November. They would take effect Jan. 1.
