Construction is set to begin on a major infrastructure improvement in Shorewood as the Village Board announced the start of the Seil Road and Bridge Reconstruction Project. The work will replace the aging Seil Road Bridge over the DuPage River while upgrading surrounding roadways to improve traffic flow and structural safety.
Patch reports that the project is being delivered by the Illinois Department of Transportation and carries an estimated construction value of $9 million. Work is scheduled to begin on March 16, with a projected timeline of approximately 15 months.
Once complete, the new bridge and roadway improvements will provide a safer and more efficient connection across the DuPage River corridor.
Bridge Replacement and Structural Improvements
At the center of the project is the replacement of the existing Seil Road Bridge, which has become load-restricted due to its age and structural limitations. Replacing the bridge will allow for improved load capacity while supporting modern traffic requirements.
Bridge replacement projects require several complex construction phases, including:
- Demolition of the existing bridge structure
- Construction of new bridge foundations and abutments
- Installation of structural girders or reinforced concrete deck systems
- Placement of new roadway surfaces and guardrail systems
Because the bridge crosses the DuPage River, construction will also require environmental coordination and careful sequencing to manage waterway impacts.
Roadway Reconstruction and Widening
Beyond the bridge itself, the project includes extensive improvements to nearby roadway segments. Seil Road will undergo reconstruction and widening in key areas to improve traffic circulation and accommodate updated roadway geometry.
One of the project’s notable features is the installation of mini-roundabouts, which can improve traffic flow and reduce collision points compared to traditional intersections.
Roadway widening projects typically involve:
- Subgrade preparation and stabilization
- Installation of new drainage systems
- Placement of base aggregate layers
- Asphalt or concrete pavement construction
- Roadside safety improvements and signage
Storm Sewer Installation
Stormwater management is also a key component of the project. The construction plan includes the installation of new storm sewer infrastructure designed to improve drainage performance along the corridor.
Storm sewer systems require excavation, pipe installation, and connection to existing drainage networks. These systems help manage runoff during heavy rain events and protect roadway foundations from water damage.
Construction Staging Plan
The reconstruction project will be completed in three major construction stages to manage work sequencing and traffic impacts.
Stage 1: Bridge Construction and Utility Work
- Installation of storm sewer infrastructure
- Initial bridge construction activities
- Roadway widening and intersection upgrades
- Installation of mini-roundabouts
Stage 2: Roadway Reconstruction
- Continued bridge construction work
- Reconstruction and widening of Seil Road
- Improvements between Canterbury Drive and River Bluff Drive
Stage 3: Final Surface Installation
- Placement of final pavement layers
- Completion of roadway markings and finishing work
Phased construction allows crews to maintain site efficiency while coordinating multiple construction tasks across the corridor.
Traffic Management and Lane Closures
Construction activity will begin with temporary lane closures along Seil Road between Raven Road and River Bluff Drive, including the Seil Road and Raven Road intersection.
Later in March, the bridge and surrounding roadway segments are expected to undergo full closures to allow for major structural work. Once contractors confirm the exact dates, the Village will notify residents and motorists in advance.
Traffic detours and alternate routes will help minimize disruption while construction is underway.
Construction Trades Supporting the Project
A bridge and roadway reconstruction project of this scale typically involves coordination across numerous specialized construction trades, including:
- Excavation and earthwork crews
- Bridge demolition specialists
- Structural concrete contractors
- Steel fabrication and erection teams
- Storm sewer and drainage installers
- Asphalt paving contractors
- Roadway striping and signage installers
- Traffic control and safety crews
These teams work together through multiple construction phases to deliver both the bridge structure and the surrounding roadway upgrades.
Project Timeline and Community Impact
With a 15-month construction schedule, the project is expected to continue through multiple construction seasons before reaching completion.
During that time, residents and drivers traveling through the Seil Road corridor should expect changing traffic conditions and occasional detours.
Once finished, the upgraded bridge and roadway network will provide improved capacity, updated infrastructure, and safer travel conditions for the Shorewood community.
The Seil Road and Bridge Reconstruction Project represents an important investment in maintaining reliable transportation infrastructure across the DuPage River corridor while supporting future growth and mobility in the area.
