Autos and pedestrians on the cantilever bridge. There will also be a driveway under the bridge for access to Green St to the west, so there are 3 auto exits from the building and 4 pedestrian exits. Really a very complex building on a weird multilevel site. Chicago has plenty of multilevel areas, but usually they pretend to be a traditional city if seen from the upper level. This is much weirder, reminds me of Hong Kong or La Defense.
Pedestrian Exits:
-East to Union St at lower level
-East to Jewel shopping center at upper level (bridge)
-West to Green St at lower level
-West to Halsted St at upper level (bridge)
Auto Exits:
-East to Union St at lower level
-West to Green St at lower level
-West to Halsted St at upper level (bridge)
Not sure why so many auto exits are needed, except that Halsted is gridlocked most of the time. The city may require the building to close the Halsted driveway during daylight hours to manage the traffic.
