They've also started big time on all the roadwork. Hayes Drive is completely ripped out in certain sections. They have laid the roadbed to add a 3rd lane to LSD southbound, and they are starting to deconstruct the retaining walls and bridge abutments to widen those bridges for the 3rd lane as well.
The Park District has also fully restored the comfort station near MSI's Omnimax, with all the stonework repointed, new faux-slate roof, restored windows, and I'm sure the interior is now updated and fully ADA-accessible. Looks like they are just about finished. Hopefully they cut back the trees so the roof doesn't get crushed again by a falling branch.
