Nope, not the airport expansion or new runway- but rather the nice overhangs at the passenger dropoff area to protect us from snow and rain. This has been going on for 8 years, and the city is charging the engineers and contractors with massive errors and cost overruns. http://www.nbcchicago.com/traffic/transit/ohare-project-budget-125054414.html To start with, it seems the engineers didn't notice the pedestrian tunnels underneath, and designed support columns without taking that into consideration. The contractor or subcontractors are accused of substituting lower quality steel in place of the specified grade, and of doing the welds incorrectly. (it seems welds are already rusting and breaking). The city is suing, and alleging fraud. The original project estimates were around 205 million, it's currently around $280M. For comparison, Sears (Willis) tower took 4 years to build, this has been ongoing for 8 years.
