One is a parking lot that is owned by the state near the Cermak-Chinatown CTA Red Line station, and three are privately held buildings, officials said. The buildings that will need to be acquired are on the northwest corner of Wentworth and Cermak: 202, 204 and 208 W. Cermak Road, according to CDOT.
