The Chicago Transit Authority will begin work to replace Purple Line track ties next month in a project that’s scheduled to last through November.
Work will be done at night during the week and during the day on weekends.
The project is designed to help reduce slow zones along the line. Over 6,000 aging railroad ties will be replaced. It’s the first major upgrade to Purple Line railroad ties since 1976.
The replacement work will be done by CTA staff and will begin in south Evanston and move north.
CTA officials say they’ll do the biggest and most disruptive portions of the project in the spring and fall — to minimize impact on residents who’ll have their windows open during the summer.
They say the work has to be done at night for worker safety and to minimize disruption for CTA riders.
The officials say the CTA changed its construction methods so the loudest portion of the work will occur earlier in the work evening.
CTA will distribute flyers to residents prior to work in affected neighborhoods. Residents can find more information on this project or sign up for e-mail updates online.
For questions regarding this project, please contact the City of Evanston Intergovernmental Affairs Coordinator Matt Swentkofske at 3-1-1 or at firstname.lastname@example.org or CTA Senior Government Officer Ryan Mouw at email@example.com.
