Yesterday, the League of American Bicyclists officially upgraded DC’s Bike Friendly Community (BFA) award from silver level to gold level, signifying a high level of success for an American city in creating a safe and convenient biking environment.

DC is the first large eastern city to reach gold level. New York, Boston, and Philadelphia, as well as Arlington and Alexandria, are all silver.

BFA awards come in bronze, silver, gold, and platinum levels. Something about the methodology seems to favor western cities, as gold and platinum locations skew heavily to the west. On the east coast, there are no platinum winners, and so far only Cambridge & Somerville, MA, and Hilton Head, SC, have achieved gold. And now DC.
