To find the approximate number of the closest cross street, divide the building number by a divisor (generally 20) and add (or subtract) the "tricky number" from the table below: and there is about between each pair of east–west streets, for ten land lots between each pair of streets. The exceptions are
Riverside Drive, as well as
Fifth Avenue and
Central Park West between 59th and 110th streets, which use a divisor of 10. The "tricky number" often corresponds to a street near the southern end of the avenue. • East End Avenue address numbers are continuations of Avenue B address numbers, since the avenue was originally called Avenue B.
Examples For example, if you are at 62
Avenue B, 62 \div 20 \approx 3, then add the "tricky number" 3 to give 6. The nearest cross street to 62 Avenue B is
East 6th Street. If you are at 78
Riverside Drive, 78 \div 10 \approx 8, then add the "tricky number" 72 to give 80. The nearest cross street to 78 Riverside Drive is
West 80th Street. If you are at 501
5th Avenue, 501 \div 20 \approx 25, then add the "tricky number" 18 to give 43. The nearest cross street to 501 5th Avenue is actually
42nd Street, not
43rd Street, as the Manhattan address algorithm only gives approximate answers. ==See also==
