History

—each had their own terminal on the edges of downtown Chicago. Charles Tyson Yerkes masterminded the linking of these railroads. The Union Loop was constructed in separate sections: the Lake Street 'L' was extended along the north side in 1895; the Union Elevated Railroad opened the east side along Wabash Avenue in 1896 and the west side along Wells Street in 1897; and the Union Consolidated Elevated Railroad opened the south side along Van Buren Street in 1897. Originally there were 12 stations, with three stations on each side. The construction of the west-leg of the Union Loop over Wells Street required the removal of the southern platform of the Fifth/Lake
Fifth/Lake (Union Elevated Railroad)
Fifth/Lake was a station on the Union Elevated Railroad's Loop, which is now part of the Chicago Transit Authority's Loop. The station was located at Fifth Avenue and Lake Street in downtown Chicago. Fifth/Lake opened on September 22, 1895 and closed on December 17, 1899....

 caused the removal of the rest of the station as the remaining platform sat across the new road's entry point. This left 11 stations, two on the north leg of the loop and three on each other leg.

The Loop was born in political scandal: upon completion, all the rail lines running downtown had to pay Yerkes's operation a fee, which raised fares for commuters; when Yerkes, after bribery of the state legislature, secured legislation by which he claimed a fifty-year franchise, the resulting furor drove him out of town and ushered in a short-lived era of "Progressive Reform" in Chicago.
