I thought it was interesting too considering the roscoe section and Belmont station are a neutral gray or white. The green is really subtle but looks nice

Yeah, temporary tracks are known as "shooflys" in railroad jargon.
I'm not sure if these are temporary though, if they were temporary I would just expect CTA to close the alley for a few months and throw up something quick. But the new track there looks permanent and they put in some complicated steelwork to straddle the alley.
It looks like they're starting the cutover process for the new flyover as well, they will need to demolish part of the Belmont station deck from 2009 and slide in the ready-made, wider deck they've been building alongside the tracks.
