Arlington County Republicans are protesting the addition of bike-sharing stations to the Rosslyn and Courthouse Metro stations, saying the loss of parking spaces could hurt businesses there.

Four Capital Bikeshare stations, which allow riders to rent bikes at one location and return them at another, were added last week. Eight parking spaces were eliminated to accommodate them.

"Parking throughout the [Rosslyn-Ballston] corridor is particularly tight," said Jeffrey Miller, a spokesman for the Arlington County Republican Committee. "It's very difficult when you have business for there to be enough daily parking."

Miller said the county's Democratically controlled board could have been more creative when choosing bike locations. A station at the corner of Lynn Street and 19th Street in Rosslyn, for instance, could have been installed one block north at Gateway Park, he said.

Rosslyn Business Improvement District Executive Director Cecilia Cassidy said the organization supports the Bikeshare stations. Similar stations at the Pentagon and Crystal City have proven popular.

"When we do take up motor vehicle space and re-purpose it for bike-sharing, the space is likely receiving more use than it was previously by a motor vehicle trip, which are usually done by a single-occupant vehicle," said Paul DeMaio, the county's bike-share consultant.
