Metropolitan Washington Airport Authorities officials say they will hold a series of public meetings this fall to discuss increases on the Dulles Toll Road.
MWAA officials said at a meeting on Wednesday that tolls are going to rise - the unknown is by how much.
"I don't want to mislead anyone. Tolls have to go up," Andrew Rountree, MWAA's chief financial officer, told The Washington Post. "There's a minimum level of toll increase that really has to occur in order for the board to meet its responsibilities."
Dates for the meeting have not been set.
Tolls are already slated to rise 50 cents Jan. 1, 2013, and some projections say the cost of driving from the Capital Beltway to Dulles International Airport could double from the current one-way toll of $2.25.
The increases are necessary to help fund Metrorail's Silver Line Phase 2. Phase 2 of the Silver Line, which will run from Reston's Wiehle Avenue to Dulles and into Loudoun County, was recently given the greenlight by Loudoun County's Board of Supervisors. Unlike the first phase, which will end at Wiehle and will be operational by late 2013, Phase 2 is receiving no federal money.
Meanwhile, advocacy group
The group, a division of the Reston Citizens Association, says a one-way trip could cost $20 in 2050 — and divert nearly 100,000 cars off the toll road and onto area streets.
