Earlier this month, we wondered whether Capital Bikeshare would have the capacity to handle a thousands of riders who took advantage of a deal offering a year-long membership for half-price. District Department of Transportation spokesperson John Lisle wasn’t too worried about it at the time, though, telling DCist that DDOT had “a plan to expand the system to help meet that demand” which included new stations in Arlington and D.C., some of which would “be installed before the end of the month.” He wasn’t kidding — during a press conference this morning, Mayor Vince Gray and transportation officials announced plans to install for several new stations around the District, including one located right in front of city hall.

City officials cut the ribbon on the Wilson Building docks at 14th and D Streets NW this morning, while five more stations are expected to open over the next week at former SmartBike sharing stations near Farragut Square, at the Metro Center, Foggy Bottom and Judiciary Square Metro stations, as well as the National Portrait Gallery. The system also recently added four new stations in Arlington. In total, DDOT plans to add 25 new stations and 250 additional bikes this summer.
