Had it become reality, the train line would have run from what was then called the University of Illinois at Chicago Circle campus at Morgan and Harrison streets, extend north on Morgan to Monroe, and then follow Monroe to the lakefront downtown, according to a city of Chicago report on the plan. Near the lakefront, the subway would have split into north and south branches, with the north line running through the 210 N. Stetson site under the Illinois Center. The north route would have terminated in a loop in the Gold Coast.
