Some of it is far west side of Elgin, on Route 20. The other shots are I90 out between Genoa and Marengo.
It is actually video shot at 24fps, rather than true timelapse (so I guess that is a misnomer). Stabilization was done with Microsoft Hyperlapse and increased to 60 fps, and ported to Adobe Premiere for a bit more stabilization. The I90 footage was crazy, 35+ mph winds according to Healthy Drones at altitude. Never will fly in winds like that again......
