====2015 embankment collapse====
On May 17, 2015, a section of the [[Embankment (transportation)|embankment]] west of McCormick Boulevard collapsed, causing the entire track to be damaged.<ref>{{Cite news |last1=Rodriguez |first1=Meredith |last2=Isaacs |first2=Mike |date=May 18, 2015 |title=Yellow Line to Skokie out of service for next several days, CTA says |url=http://www.chicagotribune.com/news/local/breaking/ct-yellow-line-cta-20150518-story.html |access-date=23 May 2015 |work=Chicago Tribune}}</ref> The collapse was due to a failure in construction at the adjacent O'Brien Water Reclamation Plant. No trains could operate either way due to the track condition. At 10:00&nbsp;PM on that day, an emergency closure of the Yellow Line was called. Yellow Line service returned on October 30, 2015, with the CTA offering free rides for one week and free parking at the Dempster-Skokie Terminal through the end of 2015.
