Street layoutEdit

File:Aerial view of Loyola station, September 2019.JPG
Much of Chicago's street system follows a grid pattern.

Chicago's streets were laid out in a grid that grew from the city's original townsite plan platted by James Thompson. Streets following the Public Land Survey System section lines later became arterial streets in outlying sections. As new additions to the city were platted, city ordinance required them to be laid out with eight streets to the mile in one direction and 16 in the other direction. A scattering of diagonal streets, many of them originally Native American trailsTemplate:Citation needed, also cross the city. Many additional diagonal streets were recommended in the Plan of Chicago, but only the extension of Ogden Avenue was ever constructed. In the 1950s and 1960s, a network of superhighways was built radiating from the city center.<ref>Template:Cite encyclopedia</ref>

As the city grew and annexed adjacent towns, problems arose with duplicate street names and a confusing numbering system based on the Chicago River. On June 22, 1908, the city council adopted a system proposed by Edward P. Brennan;<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> amended June 21, 1909. The changes were effective September 1, 1909 for most of the city.<ref name=1909snc>Template:Cite book</ref>

Addresses in Chicago and some suburbs are numbered outward from baselines at State Street, which runs north and south, and Madison Street, which runs east and west.

File:State and Madison 2010.JPG
The division of Chicago's directional address system is at State Street - separating East (E) from West (W), and Madison Street - North (N) from South (S).

A book was published in 1909 by The Chicago Directory Company indexing the old and new street numbers for most of Chicago. This volume is available online in PDF format indexed by initial letter, Plan of Re-Numbering, City of Chicago, August 1909.<ref name="1909snc"/> The opening text of the book says: EXPLANATORY Template:Cquote

The downtown area did not conform to this system until April 1, 1911, per an amendment to the law on June 20, 1910. Downtown was defined as Lake Michigan on the east, Roosevelt Road (Twelfth Street) on the south, and the Chicago River on the north and west. The addition to cover downtown was published, and is also on line as a pdf indexed by downtown street name.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

This additional paragraph explained the downtown changes:

Template:Cquote

Chicago house numbers are generally assigned at the rate of 800 to a mile. The only exceptions are from Madison to 31st Street, just south of downtown. Roosevelt Road (previously Twelfth St) is one mile south of Madison with 1200 addresses to the mile, Cermak Road (previously 22nd Street) is two miles south of Madison with 1000 addresses to the mile, and 31st Street (3100 S) is three miles south of Madison with 900 addresses to the mile.<ref name="1909snc"/> South of 31st Street, the pattern of 800 to the mile resumes, with 39th Street the next major street, 47th after that, and so on. Individual house numbers are normally assigned at the rate of one per 20 feet of frontage. Thus the last two digits of house numbers generally go only as high as 67 before the next block number is reached. Higher house numbers are found on diagonal streets and have sometimes been assigned by request.

The blocks are normally counted out by "hundreds," so that Chicagoans routinely give directions by saying things such as "about twelve hundred north on Western" or "around twenty-four hundred west on Division" (which both describe the intersection of Western Avenue (2400 W) and Division Street (1200 N)).

South of Madison Street most of the east–west streets are simply numbered. The street numbering is aligned with the house numbering, so that 95th Street is exactly 9500 South. "Half-block" east–west thoroughfares in this area are numbered and called places; 95th Place would lie just south of and parallel to 95th Street, and just north of 96th Street.

Every four blocks (half-mile) is a major secondary street. For example, Division Street (1200 N) is less important than either Chicago Avenue (800 N) or North Avenue (1600 N), but is still a major thoroughfare. However, this is not always the case; for example, on the city's Far North Side, Peterson Avenue (6000 N) is a more heavily trafficked street than Bryn Mawr Avenue (5600 N), which sits exactly at the 7-mile marker. U.S. Route 14 is routed along Peterson between Clark Street at 1600 W and Cicero Avenue at 4800 W, whereas Bryn Mawr is discontinuous, split into two segments in this part of the city by Rosehill Cemetery between Damen and Western Avenues.

Even-numbered addresses are found on the north and west sides of a street, and odd numbers are found on the south and east sides, irrespective of the streets' position relative to the corner of State and Madison.

Diagonals, even if they were to run exactly 45 degrees off of the cardinal directions, are numbered as if they were north–south or east–west streets. Examples are North Lincoln Avenue and Ogden Avenue, which bends at Madison and changes from North Ogden to West Ogden.

The northernmost street in Chicago is Juneway Terrace (7800 N), just north of Howard Street. The southern boundary is 138th Street. The eastern boundary of Chicago is Avenue A/State Line Road (4100 E) along and south of 106th Street, and the furthest west the city extends is in the portion of O'Hare International Airport that lies in DuPage County, just east of Elmhurst/York Road.

Street namesEdit

Template:See also {{ safesubst:#invoke:Unsubst||date=__DATE__ |$B= {{ safesubst:#invoke:Unsubst||date=__DATE__ |$B= Template:Ambox }} }} While all north–south streets within city limits are named, rather than numbered, smaller streets in some areas are named in groups all starting with the same letter; thus, when traveling westward on a Chicago street, starting just past Pulaski Road (4000 W), one will cross a mile-long stretch of streets which have names starting with the letter K (From east to west: Keystone (North Side)/Komensky (South Side), Karlov, Kedvale, Keeler, Kildare, Kolin, Kostner, Kenneth, Kilbourn, Kolmar, Kenton, Knox, Kilpatrick, Keating), giving rise to the expression "K-town". These streets are found approximately in the 11th mile west of the Indiana state line, and so begin with the 11th letter of the alphabet. A mile later, just past Cicero (4800 W), the starting letter changes to L, and mile by mile the letters progress up to P. Additionally, for most of the first mile west of the Illinois/Indiana state line, streets are lettered from Avenue A (S State Line Road) at the state line (4100 E) to Avenue O (3430 E), forming the A group. The areas that might otherwise be the B through J groups are the older parts of the city where street names were already well established before this system was developed (although some small groups of streets seem to have been given names intended to conform to the system), and the Q group (8800 to 9600 W) would fall west of the city, as the only land in Chicago west of 8800 West is O'Hare International Airport, undeveloped forest preserve, and a small strip of land connecting O'Hare to the rest of the city and containing only Foster Avenue.

SuburbsEdit

Some suburbs number their east–west streets in a continuation of the Chicago pattern, and even more number their houses according to the Chicago grid. A few suburbs also number their north–south avenues according to the Chicago grid, although such numbering vanished from Chicago itself long ago (the alphabetical naming scheme was devised to help eliminate it). For example, the 54th/Cermak terminus of the Pink Line is located near the intersection of 54th Avenue and Cermak Road (22nd Street) in Cicero. This is 54 blocks west of State Street in Chicago. A minor street Template:Frac blocks west of State Street would be called 54th Court (in reality, that is Lotus Avenue in Chicago).

This pattern continues as far west as Plainfield, which has a 252nd Avenue, as far north as Skokie at Central Street (10100 North),<ref>Template:Cite map</ref> and as far south as the southern edge of Will County. Suburbs that follow the Chicago numbering system include Berwyn, Bridgeview, Brookfield, Burbank, Channahon, Chicago Heights, Cicero, Crystal Lake, Elwood, Evergreen Park, Franklin Park, Justice, Lincolnwood, Matteson, Monee, Morris, Morton Grove, Niles, North Chicago, Oak Forest, Oak Lawn, Orland Park, Oswego, River Grove, Rosemont, Skokie, Westchester, unincorporated parts of Des Plaines, Glenview, and other parts of Cook County, Will, DuPage, Kendall, and Grundy Counties. Other suburbs, including Evanston, Park Ridge, Oak Park, Glenview and Wilmette use their own numbering systems. The six "collar" counties (DuPage, Kane, Kendall, Lake, McHenry, and Will) use State and Madison as a base line. For example, 32W000 in DuPage County is 32 miles west of State Street, 38000 in Lake County would be 38 miles north of Madison Street, and is normally used without the direction letter. In these counties, unlike Chicago, numbering is 1,000 numbers to the mile, so in DuPage County Template:Frac miles west is 32W500.

Some Chicago suburbs in adjoining Northwest Indiana also use the Chicago numbering system. These include East Chicago, Whiting, and Hammond. There are even examples further south in Lake County in Dyer and Schererville such as 205th Place through 215th Street (these examples coordinate with the Chicago grid, not the Gary street system). Other municipalities, such as Highland, and Griffith are based on the Gary, Indiana numbering system, beginning with 5th Avenue in Gary and increasing numerically as one travels southward. Examples in Scheider in the far south of Lake County, Indiana go as far down as 244th Avenue.

The aforementioned pattern also occurs in Waukegan, Illinois, with Washington Street being the baseline between north and south. Nearby municipalities such as Gurnee, Park City, and North Chicago continue with the Waukegan numbering pattern, while rural areas in Lake County, Illinois follow the Chicago grid.

DowntownEdit

The density of main streets in downtown Chicago is greater than in the rest of the city, with some at half-block spacing (just 50 address numbers or one-sixteenth mile from the next parallel street), or block spacing between main streets, unlike the rest of the city where the main streets are spaced at half-mile and mile intervals: Template:Columns-start

The following streets run diagonally through Chicago's grid system on all or part of their courses. These streets tend to form major 5 or 6-way intersections. In many cases they were Indian trails, or were among the earliest streets established in the city. Diagonals are numbered as north–south or east–west streets. Examples are North Lincoln Avenue and Ogden Avenue, which bends at Madison and changes from North Ogden to West Ogden. Template:Div col start

Template:Jct The route enters through the southeastern part of the city from Indiana with U.S. Route 12 and U.S. Route 20, underneath the Chicago Skyway Toll Bridge. At 95th Street, when US 12 and US 20 turn west, it continues north along the lakefront, especially via Lake Shore Drive. US 41 then departs from Lake Shore Drive at Foster Avenue. From Foster Avenue, US 41 continues northwest on Lincoln Avenue, finally exiting Chicago at Devon Avenue into the suburb of Lincolnwood.
Template:Jct The route comes north from Kentucky and intersects U.S. Route 12 and U.S. Route 20 at 95th Street west of Chicago. The three routes go north on LaGrange Road, then US 12 and US 45 continue north on Mannheim Road past O'Hare Airport and into Des Plaines. Separating from US 12, it follows the Des Plaines River as Des Plaines River Road, then continues north on Milwaukee Avenue towards Wisconsin.<ref name=rmchi07 /><ref name=illat96 /><ref name=gogm13 />
Template:Jct
Template:Jct The route started downtown and followed Ogden Avenue west out of the city, then southwest to Joliet and on to St Louis. Status as a U.S. Route in Illinois was discontinued in 1974 largely due to Interstate 55 paralleling the stretch. Some remnants are signed as historic.<ref name=illmaps13 />

County roadsEdit

Cook County has a modest amount of county roads after plans were made in 2009 to designate many roads on county ownership as a public service.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Only the designated streets in the townships of Lemont, Palos, Orland, Bremen, Lyons (south of the rivers) and Wheeling have the blue pentagon signs that are used to demarcate county roads.Template:Citation needed
