{{main|Red Ahead}}
In spring 2012, the CTA started a station and track rehabilitation program dubbed "Red Ahead",<ref name=" redahead">{{Cite web |title=CTA Red Ahead Program |url=http://www.transitchicago.com/redahead/ |access-date=August 18, 2012 |website=Chicago Transit Authority}}</ref> beginning on the North Side Main Line, which is called the "Red North" project.<ref>{{Cite web |title=Red Ahead: CTA Red North |url=http://www.transitchicago.com/rednorth/ |access-date=August 18, 2012 |website=Chicago Transit Authority}}</ref> The program monitors the full route of the Red Line, excluding the Loyola, Bryn Mawr, Sheridan, or Wilson station.<ref>{{cite web|title=Red North – Section 2|url=http://www.transitchicago.com/rednorth/#sheridan-brynmawr-loyola|publisher=Chicago Transit Authority|access-date=August 18, 2012}}</ref> This also does not include stations between Wilson through Fullerton, nor the State Street subway. In May 2012, the CTA started to work on the North Side Main Line stations of the Red Line which includes Jarvis, Morse, Granville, Thorndale, Berwyn, Argyle and Lawrence. The stations are listed in order, starting at Granville, then Morse, Thorndale, Argyle, Berwyn, Lawrence and finally Jarvis. This project started in June 2012 and was completed in December 2012. This project is also part of the Red Ahead's "Red & Purple Modernization" Project.<ref>{{Cite web |title=CTA Red & Purple Modernization project |url=http://www.transitchicago.com/rpmproject/ |access-date=August 18, 2012 |website=Chicago Transit Authority}}</ref>

The Red & Purple Modernization Project will include a redesign of a [[level junction|diamond junction]] north of Belmont Station into a [[flying junction|flyover]] for Brown Line trains. This project will decrease train backups and increase the number of trains that can cross the junction per hour.<ref>{{Citation |title=Red and Purple Modernization: Rebuilding Vital Infrastructure For Chicago's Future |date=April 23, 2015 |url=http://www.transitchicago.com/assets/1/rpmproject/2015-04-23_15sw036_RPM_One_Sheet.pdf |df=mdy-all |archive-url=https://web.archive.org/web/20180124163242/http://www.transitchicago.com/assets/1/rpmproject/2015-04-23_15sw036_RPM_One_Sheet.pdf |publisher=Chicago Transit Authority |access-date=January 19, 2018 |archive-date=January 24, 2018 |url-status=dead}}</ref> The project was criticized by 2015 mayoral candidate [[Chuy García]] and local residents in the [[Lakeview, Chicago|Lakeview]] neighborhood who organized a referendum to stop it.<ref>{{Cite news |last=Swartz |first=Tracy |date=March 2, 2015 |title=Chicago Mayoral Candidates Sound off on Transit Priorities |work=Chicago Tribune |url=http://www.chicagotribune.com/news/columnists/redeye-chicago-mayoral-candidates-on-transit-20150302-story.html |access-date=January 19, 2018}}</ref><ref>{{Cite news |last=Swartz |first=Tracy |date=November 6, 2014 |title=Lakeview Residents Vote: CTA Hasn't 'Sufficiently Justified' Belmont Flyover |work=Chicago Tribune |url=http://www.chicagotribune.com/news/local/breaking/redeye-chicagoans-vote-on-cta-belmont-flyover-referendum-20141104-story.html |access-date=January 19, 2018}}</ref> The [[Federal Transit Administration]] passed the CTA's environmental review on the flyover in January 2016 and received a $1.1&nbsp;billion federal grant the following year.<ref>{{Cite news |last=Greenfield |first=John |date=January 26, 2016 |title=The Controversial Belmont Flyover Has Federal Approval—But Still Faces Other Hurdles |work=Chicago Reader |url=https://www.chicagoreader.com/chicago/belmont-flyover-controversy-cta-modernization/Content?oid=21007763 |access-date=January 19, 2018}}</ref><ref>{{Cite news |last=Dudek |first=Mitch |date=January 9, 2017 |title=Obama Sends CTA $1.1 Billion for Red Line Improvements |work=Chicago Sun-Times |url=https://chicago.suntimes.com/chicago-politics/obama-sends-cta-1-1-billion-for-red-line-improvements/ |access-date=January 19, 2018 |archive-date=January 20, 2018 |archive-url=https://web.archive.org/web/20180120070914/https://chicago.suntimes.com/chicago-politics/obama-sends-cta-1-1-billion-for-red-line-improvements/ |url-status=dead }}</ref> 16 properties affected by the flyover were demolished.
