SQN provided construction management support for the rehabilitation of seven stations along CTA’s North Red Main Line. The project modernized aging station infrastructure through track-level waterproofing and drainage improvements, track reconstruction, replacement of existing wood platforms with precast concrete platforms, viaduct pier repairs, and upgrades to station platforms and stationhouses. The work improved the safety, reliability, and long-term service life of one of CTA’s busiest rail corridors.
