Bank One Tower

Bank One Tower is a 60-story skyscraper completed in 1969, and located in the Chicago Loop district at 10 South Dearborn Street.

Overview
The building is 850 feet tall and - as of 1999 - was the ninth tallest building in Chicago, and the twenty-ninth tallest in the United States. It is also the tallest building in the Chicago's "Loop proper" - as delineated by the looping route of The El's aerial tram tracks - and is therefore its geographic central point. The building is the headquarters of Bank One Corporation.

Trivia

 * Curiously, while the building should have a large, two-level terraced sunken plaza on its South side, it is not present in-game. In real life, this area is one of the three most important plazas between Clark Street and Dearborn Streets (the other two being Daley Plaza and Federal Center Plaza), and features several staircases and a sizable fountain at the bottom.
 * Instead, in Midtown Madness, the building is located next to a grass-covered square.
 * In real life, Bank One Tower and its plaza span an entire city block bounded by Clark, Dearborn, Monroe and Madison Streets. Due to the change in the city's layout, this is not the case in the game.
 * Currently, in 2021, the building is the eleventh tallest building in Chicago, and the 40th tallest in the United States. It remains, however, the tallest building within the confines of the "El" Loop elevated tracks.
