Chicago's streets were laid out in a [[Grid plan|street grid]] that grew from the city's original townsite plot, which was bounded by Lake Michigan on the east, North Avenue on the north, Wood Street on the west, and 22nd Street on the south.<ref>{{cite web |url=http://www.wbez.org/series/curious-city/gulp-how-chicago-gobbled-its-neighbors-109583 |title=Gulp! How Chicago Gobbled Its Neighbors |access-date=April 20, 2016 |archive-url=https://web.archive.org/web/20160115150008/http://www.wbez.org/series/curious-city/gulp-how-chicago-gobbled-its-neighbors-109583 |archive-date=January 15, 2016 |url-status=dead}}</ref> 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 sixteen in the other direction, about one street per 200 meters in one direction and one street per 100 meters in the other direction. The grid's regularity provided an efficient means of developing new real estate property. A scattering of diagonal streets, many of them originally Native American trails, also cross the city (Elston, Milwaukee, Ogden, Lincoln, etc.). Many additional diagonal streets were recommended in the [[Burnham Plan|Plan of Chicago]], but only the extension of [[Ogden Avenue (Chicago)|Ogden Avenue]] was ever constructed.{{sfnp|Condit|1973|pp=31, 52–53}}

In 2016, Chicago was ranked the sixth-most walkable large city in the United States.<ref>{{cite web |url=https://www.walkscore.com/IL/Chicago |title=Chicago neighborhoods on Walk Score |work=walkscore.com |access-date=August 31, 2016 |archive-date=November 11, 2016 |archive-url=https://web.archive.org/web/20161111155250/https://www.walkscore.com/IL/Chicago |url-status=live }}</ref> Many of the city's residential streets have a wide patch of grass or trees between the street and the sidewalk itself. This helps to keep pedestrians on the sidewalk further away from the street traffic. Chicago's [[Western Avenue (Chicago)|Western Avenue]] is the longest continuous urban street in the world.<ref name="El-KhouryRobbins2004">{{cite book |author1=Rodolphe El-Khoury |author2=Edward Robbins |title=Shaping the City: Studies in History, Theory and Urban Design |url=https://books.google.com/books?id=Dbv-zU6M9WIC&pg=PA60 |access-date=May 9, 2013 |date=June 19, 2004 |publisher=Taylor & Francis |isbn=978-0-415-26189-0 |pages=60– |archive-date=July 9, 2023 |archive-url=https://web.archive.org/web/20230709112336/https://books.google.com/books?id=Dbv-zU6M9WIC&pg=PA60 |url-status=live }}</ref> Other notable streets include [[Michigan Avenue (Chicago)|Michigan Avenue]], [[State Street (Chicago)|State Street]], [[95th Street (Chicago)|95th Street]], [[Cicero Avenue]], [[Clark Street (Chicago)|Clark Street]], and [[Belmont Avenue (Chicago)|Belmont Avenue]].
