[edit] Street layout

The streets of Chicago primarily follow the grid system established by the Chicago Board of Aldermen in 1908 and implemented on September 1, 1909. The baselines from which all streets and houses in Chicago are numbered are State Street, which runs North and South, and Madison Street, which runs East and West. Street numbers begin at "1" at the base lines and run numerically in directions indicated to the city limits. Letters (N, S, E, or W) indicate directions.

The City of Chicago is divided into one mile sections which nearly everywhere contain exactly 8 blocks to the mile. Every average block is assigned a new series of 100 numbers. Therefore, each 800 in numbers is one mile. North-south blocks in and just south of downtown are an exception to the 800-to-a-mile rule: Madison (0 N/S) to Roosevelt (1200 S) is one mile, as are Roosevelt to Cermak (2200 S) and Cermak to 31st Street (3100 S). The normal 800 rule resumes south of 31st Street so that Pershing Road (3900 S) is one mile south of 31st. 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, especially 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.

Even numbers are found on the North and West sides of the street. Odd numbers are found on the South and East sides.

While all north-south streets in (The City of) Chicago are named, rather than numbered, many of the smaller streets are named in groups all starting with the same letter; thus, when traveling westward on a Chicago road, starting just past Pulaski Road (4000 W), one will encounter a mile-long block of cross-streets most of which have names starting with the letter K. These streets are found approximately in the eleventh mile west of the Indiana state line, and so begin with the eleventh 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. The areas that might otherwise be the A 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 entirely outside the city (exclusive of the "airport extension", which is too small to contain any streets other than the Kennedy Expressway).

On the far southeast side of the city, Avenue A lies just west of the Illinois-Indiana state line. Lettered avenues mark each block through Avenue O, which is a main street through southeast side communities such as Hegewisch.

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 54/Cermak terminus of the Chicago 'L' rapid transit system 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 54½ blocks west of State would be called 54th Court.

This pattern continues west to Plainfield, which has a 252nd Avenue. Suburbs which follow the Chicago numbering system include Niles, Morton Grove, Skokie, Lincolnwood, Evergreen Park, Oak Lawn, Oak Forest, Matteson, parts of Des Plaines, and other parts of Cook County, Will, and DuPage Counties. Other suburbs, including Evanston, Park Ridge, Oak Park, and Glenview, use their own numbering systems.

Interstates in Chicago

The city of Chicago proper has seven major interstate highways crossing through it. However, the various roadways are more typically known to Chicagoans not by their Interstate numbers but rather by various given names.

[edit] Expressways in Chicago

The Kennedy Expressway (formerly the "North-West Expressway") runs from O'Hare International Airport east and south to downtown Chicago. It interchanges with the Northwest Tollway and the Tri-State Tollway near Cumberland Avenue on the city's far northwest side (not far from its western terminus at O'Hare), with the Edens Expressway near Montrose Avenue on the city's near northwest side, and with the Dan Ryan and Eisenhower Expressways and with Congress Parkway at its southern terminus downtown at the Circle Interchange near the Chicago Loop. The portion from O'Hare to the interchange with Northwest Highway and the Tri-State is Interstate 190; the remainder is signed as Interstate 90. Interstate 94 is overlaid on Interstate 90 from the junction with the Edens south to the southern terminus of the expressway.

The Edens Expressway runs south from the Cook County line (Lake-Cook Road) near Northbrook to its interchange with the Kennedy Expressway near Montrose. The Edens Spur (formally a part of the Tri-State Tollway) splits off near the north end to interchange with the mainline Tri-state. All of the Edens except for the small portion north of where the Edens Spur splits off, and all of the Edens Spur, is signed as Interstate 94; the northernmost section is signed as U.S. Highway 41. North of the northern terminus U.S. 41 continues north into Lake County as Skokie Highway. U.S. 41 is overlaid on Interstate 94 from the junction with the Edens Spur to the Skokie Road exit in Skokie.

The Dan Ryan Expressway runs south from the Circle Interchange (where it interchanges with the Kennedy and Eisenhower Expressways and with Congress Parkway) near the Chicago Loop, through the Spaghetti Bowl where it interchanges with the Stevenson Expressway (Interstate 55), then past an interchange with the Chicago Skyway near 66th Street, to its southern terminus in south Chicago, where it interchanges with the Bishop Ford Freeway and continues southwest through south Chicago and the southern suburbs toward Champaign-Urbana. The Dan Ryan is signed as Interstate 94 until it interchanges with Bishop Ford Freeway and is then signed as Interstate 57; the portion between the Circle Interchange and the junction with the Chicago Skyway is overlaid with Interstate 90.

The Eisenhower Expressway (Interstate 290; formerly "Congress Expressway") runs from the Circle Interchange near the Loop almost due west to Chicago's western suburbs, interchanging with the Tri-State Tollway and the eastern terminus of the Ronald Reagan Memorial Tollway (Interstate 88) near Hillside, Illinois, after which it turns northwest (as the "Eisenhower extension") and eventually terminates at the Northwest Tollway near Schaumburg. The name "Congress Parkway" persists for the short section east of the Circle Interchange, which connects the three major expressways to Lake Shore Drive (U.S. 41).

The Stevenson Expressway (Interstate 55) has its northern terminus at the Spaghetti Bowl, where it interchanges with the Dan Ryan, and heads southwest through the south and southwestern neighborhoods of Chicago, past Midway Airport, and out of Chicago. After leaving Chicago it intersects with the Tri-State Tollway and then heads southwest out of the Chicago area toward Joliet (where it intersects Interstate 80) and on into central Illinois.

The Bishop Ford Freeway starts at the southern terminus of the Dan Ryan Expressway and heads first southeast and then south through southern Chicago and into Chicago's southern suburbs, where it intersects with the western end of the Kingery Expressway and the eastern end of the Tri-State Tollway, then continues on further into the south suburbs before downgrading to a surface highway and eventually terminating into Dixie Highway (Illinois Route 1) south of Crete, Illinois. The portion of the Bishop Ford Freeway north of the interchange with the Kingery Expressway is signed as Interstate 94; south of that point it is signed as Illinois Route 394.

The Chicago Skyway angles off from the Dan Ryan Expressway near 66th Street and heads southeast toward Indiana. Whether or not the Skyway is part of Interstate 90 is a matter of some debate. The eastern end of the Skyway ends with toll bridge over the Little Calumet River and (incidentially) the Indiana state line; on the other side of the state line the Skyway ends at the western terminus of the Indiana Toll Road.

The Tri-State Tollway only enters Chicago at one point: its interchange with the Kennedy Expressway and North-West Tollway on the far northwest side. Otherwise, the Tri-State circumvents the city of Chicago entirely, running entirely through the suburbs from its northern terminus near the Wisconsin border to its southern terminus at the interchange with the Bishop Ford Freeway and the western end of the Kingery Expressway. North of the junction with the Edens Spur the Tri-State is signed as Interstate 94; south of this it is signed as Interstate 294, and the southern part of that is overlaid by Interstate 80 (which continues east past the eastern terminus of Interstate 294 as the Kingery Expressway and on into Indiana).

South Lake Shore Drive, looking north into the heart of the city

Lake Shore Drive is a major highway running along the Lake Michigan shoreline from Hayes Drive (63rd Street) in southern Chicago to the intersection of Hollywood Avenue and Sheridan Road in Chicago's Edgewater neighborhood. For most of its length, Lake Shore Drive is signed as U.S. Highway 41. Parts of Lake Shore Drive are constructed at or near expressway grade, but there are a number of at-grade intersections, especially near downtown. Nonetheless, "LSD" (as it is often referred to) is a major arterial with a great deal of cultural as well as transportation significance to Chicagoans.

[edit] U.S. highways

U.S. Highway 41 enters through the southeastern part of the city from Indiana as a part of U.S. 12 and U.S. 20, underneath the bridge linking the Chicago Skyway and the Indiana Toll Road. It traverses the southeast side of the city until it becomes South Shore Drive, and eventually Lake Shore Drive. U.S. 41 then departs from Lake Shore Drive at Foster Avenue. From Foster Avenue, U.S. 41 continues northwest on Lincoln Avenue, finally exiting Chicago at Devon Avenueinto the suburb of Lincolnwood.
U.S. Highway 14 splits off from U.S. Highway 41 at Bryn Mawr Avenue by Lake Michigan on the north side of the city. U.S. 14 then recrosses U.S. 41 and eventually exits the city as Caldwell Avenue.
U.S. Highway 12 and U.S. Highway 20 enter the city proper on the far south side on 95th Street at Western Avenue. They stay together until they join U.S. 41 in the south side, and exit together into Indiana. U.S. 12 crosses back into Chicago by O'Hare Airport multiplexed with U.S. 45.
U.S. Highway 45 remains mostly outside of Chicago, crossing Interstate 190 as a part of U.S. 12 and U.S. 20. It follows the Des Plaines River as the Des Plaines River Road or Mannheim Road.

[edit] Interesting facts

On the first day of implementing the modern street numbering system 75% of the mail was incorrectly addressed.
There were thirteen streets named Washington at the beginning of the 20th century.
Chicago's longest thoroughfare is Western Avenue at 23.5 miles.
Milwaukee and Elston Avenues (both northwest-southeast diagonals) intersect twice—at 800 north (at Fry Street, just north of Chicago Avenue) and again at 6200 north (at Melvina Street, just north of Peterson Avenue).
Only Wacker Drive has buildings addressed north, south, east and west. It is the only road in Chicago to exist on both sides of both Madison Street and State Street.
