On Wednesday, the Chicago Transit Authority (CTA) approved a plan to extend the Red, Yellow, and Orange L lines. The vote clears the way for the CTA to pursue federal funding for the line extensions. Under the plan, the Red Line would gain 5.3 miles of track, four new stations, and stretch to 130th Street. The Orange Line would extend past Midway Airport with a new station at 7600 South Cicero Avenue. The Yellow Line would would gain 1.6 miles of track and one new station at Old Orchard Road. The CTA will begin Environmental Impact Statements, the next step in the federal funding process.
