The inbound Ike was blocked Tuesday afternoon at 1st Avenue for police activity.
The Eisenhower Expressway was reopened after police shut down inbound lanes at 1st Avenue for about a half hour.
State police apparently were called to the 1st Avenue overpass just before noon Tuesday for a shooting. Traffic backed up as officers walked I-290 searching for something on the road.
Cars were filtered off the interstate at 1st Avenue and were routed back onto I-290 after the exit. Officers wrapped up the search just before 1 p.m. It's unclear what they found, if anything.
