The Chinatown feeder ramp from the inbound Dan Ryan to the northbound Stevenson Expressway (I-55) wil be shut down at 9:30 p.m.
Some lanes on the northbound Stevenson north of the Ryan will also begin their shutdown at 10:30 p.m.
The Stevenson will be completely shut down by midnight between the Dan Ryan and Lake Shore Drive and will stay closed through the NATO summit.
Lake Shore Drive will also be closed from Balboa to 39th Street for the summit. It is possible that Lake Shore could begin shutting down lanes earlier Friday as well, though such an announcement has not been made.
