Metro’s board of directors will see changes this year.

Mary Hynes, the voting member to the Metro board from Arlington County, is stepping down to a non-voting seat. Jeff McKay, the alternate representative from Fairfax County, is stepping down to make room for James Dyke, a Northern Virginia lawyer who was appointed by Virginia Gov. Robert F. McDonnell to the Northern Virginia Transportation Commission, which appoints representatives to the Metro board.

The changes to the Metro board will go into effect Jan. 12 when Dyke is expected to be sworn in.

Hynes, who has served as a voting member since January 2011, said Friday that it was "hard" to have to move from a voting seat to a non-voting seat.

"We’re trying to make the best of what we view as a not-great situation," she said.

The concern, she said, is that Dyke represents Virginia and that the state "has a different priority on funding transit than we do in Arlington."

"Transit is crucial for us," she said. "If it doesn't work, our community shuts down."

She will serve as an alternate to the Metro board, taking the seat of McKay, who has served on the Metro board since 2008.

Cathy Hudgins, chair of the Metro board and a Fairfax County supervisor, said it is "very unfortunate that Fairfax County had to lose a seat," but said the NVTC group has passed a resolution to work together to "coordinate on issues" of transportation.
