The first reported YMCA swimming bath was built at the Brooklyn (NY) Central YMCA in 1885. By the end of the year, it was reported that 17 Ys had pools. Pools then bore scant resemblance to the pools of today: The Brooklyn Central pool was 14' x 45' and 5' deep.
With the new plan, construction began in 1920 and lasted until 1925, when the $6,000,000 ran out. During that time, two miles of 26-foot wide subway tunnel were built where the canal had been, and then covered by a new street, Central Parkway, creating a major thoroughfare for aboveground traffic.
