Blue Line, Eisenhower Median

From O'Hare and the northwest, the Blue Line enters the subway portal before the Division station, and then has nine underground stops as it passes into, through, and out of downtown.  It emerges again into the daylight in the median of the extremely congested Eisenhower Expy. 

Chicago was the first U.S. city to introduce heavy rail to freeway medians with this line, opened in the late 1950s.  That new Congress Service replaced the nearby Garfield Park "L," and connected with the Dearborn St. subway downtown.  The Chicago, Aurora & Elgin Interurban, which for decades had used that part of the "L" to reach the Loop, did not survive to take advantage of what would have been a much quicker ride.
This photo is from along a very brief three-track segment between the first two Blue Line outdoor stations, UIC-Halstead and Racine.
