A Fairfax County supervisor is asking for additional bus service to Reston to relieve congestion once Metro's Silver Line opens.

Fairfax County Supervisor Cathy Hudgins, D-Hunter Mill, earlier this week asked fellow board members to consider providing $2.2 million for additional Fairfax Connector bus service in Reston, the end point for the first phase of the Silver Line. The first phase of the Silver Line is expected to open late this year. Its second phase, to Loudoun County via Dulles International Airport, won't open until 2018 or later.

Hudgins said she heard from many Reston residents who want the extra service.

"Many participants urged that the system not just focus on moving commuters to and from the Silver Line stations, but also create viable alternative transportation means for all residents in the community," Hudgins said in a memo. "The change in transit philosophy will take a great deal more investment and planning."

Hudgins said she thought the bus service would be essential to reducing the congestion brought by Silver Line commuters.
