In order to complete a pavement patch at a previous water main break, Illinois American Water will be closing a northbound lane of Prospect Avenue between Hessel Blvd. and Haines Blvd. The lane closure will begin on Monday, April, 15, 2013, and will be reopened by Monday, April 22, 2013. Northbound traffic will be reduced to one lane in the area. The patch is on the Illinois Marathon route and is being restored in anticipation of this event.
