Keep those quarters handy. Starting at midnight Sunday, the base fare on New York City subways and buses is going up for the first time since 2003—from $2.00 to $2.25. Unlimiteds are also rising in price across the board, with monthly Metrocards going from $81 to $89. If you're on a weekly card or have a longer one about to expire, you might want to make a trip to your nearest subway station this evening to pick a card up the old rates. But don't think about stockpiling them—the grace period to use start using cards purchased at the old rate is Monday July 6th. Funny that the fare hikes have fallen so close to Independence Day without using the holiday for the changeover. Fourth of July was the date that both the free transfer from subways to buses (and vice-versa) debuted and unlimited Metrocards were introduced, in 1997 and 1998 respectively. Signs of this most recent change have been appearing underground this week—sometimes as seen here in as many as five languages at once.
