The County’s Annual Highway Program gives unusually detailed status information. The following projects were active in the 2026 program when this page was reviewed.
Under construction
Naperville Road from I-88 to Ridgeland Road
The corridor is being widened and resurfaced with intersection changes at Diehl Road and Naperville-Wheaton Road. The County reports shifted lanes, temporary signals, storm sewer work, and utility relocation, with completion anticipated in 2027.
What property owners should examineWider pavement and revised turns can affect commercial entrances, corner influence, stormwater facilities, and the way traffic reaches adjoining property.
Utility relocation and construction preparation
Lemont Road from 83rd Street to 87th Street
The project adds and rearranges turn lanes, replaces traffic signals, and includes storm sewers, retaining walls, sidewalks, and resurfacing. The County states that the construction start has depended on utility relocation.
What property owners should examineUtility easements, retaining walls, new drainage, and intersection widening can create permanent and temporary burdens beyond the visible road edge.
Active bridge reconstruction
Warrenville Road bridge over the East Branch DuPage River
The bridge replacement includes retaining walls, sidewalks, a path, stormwater storage, pavement reconstruction, and relocated aerial and underground utilities. Traffic has been staged across the newly built half of the bridge.
What property owners should examineBridge approaches can alter grades, drainage, and access well outside the bridge itself. Utility moves may also require separate easements across nearby property.
