Navigating Chicago is easy. Block numbers are consistent across the whole city. Standard blocks, of 100 addresses each, are roughly 1/8th of a mile long. (Hence, a mile is equivalent to a street number difference of 800.) Each street is assigned a number based on its distance from the zero point of the address system, the intersection of State Street and Madison Street. A street with a W (west) or E (east) number runs north-south, while a street with a N (north) or S (south) number runs east-west. A street's number is usually written on street signs at intersections, below the street name. Major thoroughfares are at each mile (multiples of 800) and secondary arteries at the half-mile marks. Thus, Western Ave at 2400 W is a north-south major thoroughfare, while Montrose Ave at 4400 N is an east-west secondary artery.
In general, "avenues" run north-south and "streets" run east-west, but there are numerous exceptions. (e.g., 48th Street may then be followed by 48th Place). In conversation, however, Chicagoans rarely distinguish between streets, avenues, boulevards, etc.
Several streets follow diagonal or meandering paths through the city such as Clark St, Lincoln Ave, Broadway, Milwaukee Ave, Ogden Ave, Archer Ave, Vincennes Ave, and South Chicago Ave.
