The 8.5-mile Crenshaw Line is one of several Metro rail projects now underway—when it's finished around 2019, it'll run from the Expo Line down to the Crenshaw Line. For now, work is underway at the Crenshaw/Vernon stop in Leimert Park, which will be one of the line's underground stations (Expo/Martin Luther King, Jr. and Expo/Crenshaw are the other two), but that doesn't mean there's not lots of work to watch going on above ground. Metro produced this time-lapse video (via The Source) showing the work done on the Leimert Park station "over the past couple months," showing workers digging out and covering over the station (decking), and including lots of exciting and realistic construction sounds that transport viewers right onto the job site. (To get an idea of what's going on, there's this older, animated Metro video explaining how they'll construct underground stations for the Purple Line.)

The Crenshaw Line will create eight new stations in total, and will eventually hook up to the airport via an Aviation/96th Street station and a people mover.
