芝加哥的地铁绝对不是这个数。
芝加哥downtown的地铁基本上都在地下,光downtown就有6条线路经过,肯定不止18公里。另外,downtown外也有一些是在地下的。
至于地铁的长度,光Blueline O'hare机场到downtown段至少就有大约35公里,Orange Line(到midway机场)有大约20公里。redline(北线)至少也有20公里是不从高速中间过的,Geenline 南段至少也有10公里,也是不从高速上过的。
再把所谓的expressway medians加上,绝对不止173公里。CTA上的数字是224.1英里。

Chicago has 3 million inhabitants (more than 7.5 million in the metropolitan area) and is the third largest metropolitan area in the USA (after New York and Los Angeles), situated on the western shore of Lake Michigan in the state of Illinois.
Chicago's metro is known as the 'L' as most of its network is elevated. Some stretches of today's system date back to the end of the 19th century when Chicago followed New York's example to construct elevated rail lines. Whereas New York started early in the 20th century to put all elevated lines in Manhattan underground, Chicago maintains most of its original routes. All lines spread out from the city centre where some of them form the famous elevated loop, now one of the city's landmarks. Two lines, the Blue Line and the Red Line cross the city centre north-south in a subway. Washington, Jackson and Monroe stations of both subways are connected by a 750 m (Dearborn subway) / 930 m (State St.) long continuous platform.
The entire network is 173 km long and has 151 stations, 18 km lie in a tunnel (21 stations) and 62 km are elevated (89 stations). Most of the rest of the lines and stations are in expressway medians, with the exception of several kilometers at the ends of the Brown Line and Blue Line (Douglas) branches. The 'L' is operated by CTA (Chicago Transit Authority). Both airports are served by a CTA train, O'Hare Airport by the Blue Line (45 min to city centre) and Midway Airport by the Orange Line (30 min to city centre).
On 11 Sept 2004, the Yellow Line (Skokie Swift) was converted from overhead to third rail power supply to make rolling stock compatible with other lines. [size=-1]1897 - Loop opened around city centre
