Chicago Mile by Mile

This is the web version of a set of photographs that map Chicago's famous and rarely-comprimising grid into 212 4"x6" snapshots.

Chicago street numbers start at State and Madison downtown. State Street divides east and west addresses, and Madison Street divides north and south addresses. One mile is equal to 800 street numbers.

The photographs document every intersection of mile streets - streets numbered with multiples of 800. The South Side warps the numbering system; An address at Roosevelt Road, one mile of south of Madison, is numbered 1200. A mile further brings you to 2200 (Cermak), then 3100 (31st). After that the numbering system returns to 800 a mile.
The photographs were taken between 1/2/02 and 1/22/02, during the second warmest and sunniest January on record.
