We finally have an exact date for the official opening of the $4 million Union Station Bike Transit Center: October 2 will mark the grand opening for the long-awaited (and somewhat delayed) facility, a spokesperson for Mobis/Bikestation confirmed today. The Bike Transit Center, paid for by the U.S. Department of Transportation and DDOT, will offer secure bike parking, a changing room, lockers, bike rentals, repairs and a small retail shop selling bike accessories, for about $1 a day. The facility will be the first of its kind on the East Coast, and cyclists all over the metro area have been anticipating the opening of the station for some time. See this story from the Washington Post last month for more background on the BTC.
