The Red & Purple Modernization Project will include a redesign of a diamond junction north of Belmont Station into a flyover for Brown Line trains. This project will decrease train backups and increase the number of trains that can cross the junction per hour. The project was criticized by 2015 mayoral candidate Chuy García and local residents in the Lakeview neighborhood who organized a referendum to stop it. The Federal Transit Administration passed the CTA's environmental review on the flyover in January 2016 and received a $1.1 billion federal grant the following year. 16 properties affected by the flyover were demolished. Construction on the flyover began on October 2, 2019 and will be completed by the end of 2021.
