Orange Line Extension

Project Schedule

After the scoping period, the Chicago Transit Authority (CTA) will start preliminary engineering and prepare a Draft Environmental Impact Statement (EIS). The public will have an opportunity to comment on a Draft EIS during a 45-day public comment period. During the review period, CTA will host public hearings to receive comments on the Draft EIS from the public and agencies. CTA will then prepare a Final EIS that includes responses to public comments.

The Federal Transit Administration will consider the Final EIS and prepare a Record of Decision (ROD) selecting the preferred alternative. Issuance of the ROD indicates that CTA has satisfied all of the requirements of the National Environmental Policy Act. While CTA can advance on preliminary engineering concurrently with the environmental analysis, the issuance of the ROD will allow CTA to move forward with final design and construction of the Orange Line.

Project schedule is dependent on federal reviews and approvals and funding availability.
