Interesting headline, because the construction schedule is anything but "on-track" - at least, not on the original track. Let's just say... it's on a new track. Instead of Fall 2020, the new groundbreaking is now scheduled for March or April 2021, with bid openings in January, board decisions in February, and completion sometime in 2023.
The article provides a few interior renderings that I have not seen yet - it sounds like they were just revealed to the County Commissioners yesterday. There will be a central light well, and if funding can be obtained, a prismatic art installation in collaboration with the Kalamazoo Institute of Arts.
