Experienced a significant traffic back-up approaching Arsenal Rd on I-55 in Joliet. Work on the bridge spanning the Des Plaines River has traffic down to one lane (!!!!) in both directions, see pictures in this post.
Received this update from IDOT:
The work being performed to the structures carrying I-55 over the Des Plaines River in Will County includes repairing the structural steel, patching and resurfacing the bridge decks and cleaning and painting the structures. In 2013 work was done on the southbound structures. This year (2014) work is being performed on the northbound structures. The work is expected to be completed by late August (before the Labor Day holiday). The Illinois Department of Transportation appreciates your patience as we work to repair these 60+ year old structures.
