CTA Green Line Track Renewal

In order to provide a smoother and more reliable commute, as well as proactively avoid the development of slow zones in the area, track infrastructure on the CTA Green Line between Laramie and Harlem/Lake was significantly rehabilitated for the first time since the 1980s. Over 75% of the rail ties had been approaching or had exceeded their useful life. Most of the work was performed over 7 weekend-long track closures.
