I haven't seen anything about it on CDOT's web site, so I thought I'd mention it here.
North and South Wacker Drive are going to undergo major construction soon.
Both levels of the double-decker roadway will be completely rehabbed from Randolph Street on the north to Harrison Street on the south. Expect major problems getting through the area, if you're used to using that route.
The good news is that we hear the plan includes creating a new park on top of Wacker Drive. I couldn't find any details on CDOT's web site, so it's hard to say if this will run down the median of the road, or be a complete decking over -- maybe at the south end.
Either way, the project also includes money for fixing up Oscar D'Angelo Park. "What's Oscar D'Angelo Park" you ask? See our article from June 3, 2009 about this hidden green gem that few people seem to know about.
