Is the disruption caused by local infrastructure projects worth the long-term community benefits?
The Illinois Department of Transportation has launched a phased closure of Water Street in Joliet to clear the way for bridge construction over the Des Plaines River. Crews from ComEd are currently relocating utility lines as part of the broader I-80 reconstruction project.
Why it matters
Relocating underground utility lines is a critical prerequisite for building new bridges over the Des Plaines River. This infrastructure work ensures the long-term structural integrity of the expanded I-80 highway corridor.
The utility relocation project is expected to span a total of 12 to 16 weeks across two distinct phases. Each individual closure phase for Water Street is scheduled to last three to four weeks.
The players
Illinois Department of Transportation
This state agency manages the planning, construction, and maintenance of Illinois' transportation infrastructure.
ComEd
This electric utility company provides energy services to northern Illinois and is responsible for managing local power line infrastructure.
The details
Closures on Water Street are split into two phases: the first between I-80 and Lucas Street, and the second from Lucas Street to Shelby Street. Following utility relocations by ComEd, crews will shift focus to moving water and sanitary sewer lines.

Market Landscape
This project represents a localized extension of the ongoing I-80 reconstruction project. By synchronizing utility upgrades with highway development, the region is modernizing critical infrastructure to keep pace with broader industrial and transit demands.
Local drivers in Joliet must utilize posted detours via Edward Street, River Street, and South Des Plaines Street while Water Street is closed. Commuters should prepare for potential delays and follow traffic signage to navigate the construction zones safely.
The takeaway
Large-scale highway projects often require weeks of preparatory utility work that can shift local traffic patterns. Drivers should plan extra commute time and stay informed on phase-specific road closures during this multi-month reconstruction period.
