As the end date of Greyhound’s lease at its downtown Chicago bus station approaches, the company has begun routing more buses through Gary, Indiana, a new analysis of bus schedules shows. The changes suggest a proactive response to the potential closure of the downtown station, according to the report from DePaul University’s Chaddick Institute for Metropolitan Development. The institute and advocates have been sounding the alarm about the possible closure of the downtown Chicago bus station for more than a year, saying such a move would have repercussions for low-income travelers, residents of communities without easy access to train or airline service, and others who rely on buses to travel between cities, as well as Chicago’s status as a transportation hub. The end of the lease is now fast approaching, and an executive of Greyhound’s parent company previously said if nothing changes the company will likely have to leave the facility Sept.
