Manhattan Street Locator

Manhattan is built on a grid system
with the Avenues usually running either North-South or South-North (Park is one of the exceptions);
and the cross streets running East-West (usually odd numbers) or West-East (usually even numbers)
with the occasional exceptions, including some streets that have traffic in both directions:
these include 72nd, 57th, 42nd, 34th, 23rd, and 14th.

The Avenues can run the length of Manhattan
so calculating the cross street is the best way to work out where an address is located.

For example: If the address is 1660 8th Ave
the nearest cross is approximately 92nd.

Take 1660
Cancel the last number and you are left with 166.
Divide by two which gets you to 83.
Add the Avenue number (given below)
which in the case of 8th Ave is 9...................... which brings you to 92.
