Antioch’s Centennial Park redevelopment targets substantial completion in late August

Antioch’s Centennial Park redevelopment remains under construction, with Phase 1 scheduled to reach substantial completion in late August 2026, according to the Village of Antioch’s project update.

The project is a municipal redevelopment led by the Village of Antioch and funded in part by the village and in part by the State of Illinois. That makes the work both a local capital project and a publicly funded construction effort, with the late-August milestone providing a near-term point for tracking progress.

What the milestone means

Substantial completion is a construction benchmark. It does not by itself establish that every part of the broader Centennial Park redevelopment is finished, or that all planned phases have been completed.

For residents, families and visitors, the milestone could mark a transition as Phase 1 moves toward completion. Changes in park facilities or public access may follow as construction advances, although the completion target should not be treated as confirmation that the park is already open or fully complete.

The project’s timing also gives the village a clear accountability point. By late August, residents will have a specific milestone against which to measure the project’s progress, while the village continues work on the first phase of the redevelopment.

Project scope and funding

The Village of Antioch’s update identifies Centennial Park as an Antioch municipal redevelopment project and names both the village and the State of Illinois as funding partners. The public update does not state the project’s total cost or list the specific facilities and amenities included in Phase 1.

Those details would help residents understand the financial scale of the work and which parts of the park are expected to change first. For now, the documented information establishes the project’s funding structure and its expected construction milestone, but not a complete inventory of the phase’s improvements.

What comes next

The next known benchmark is substantial completion in late August 2026. An official completion notice will be needed to confirm when the milestone is reached.

Until that confirmation, Centennial Park remains an active construction project rather than a completed redevelopment. Residents and visitors can use the village’s late-August target as the next date to watch for updates about progress, access and the facilities delivered through Phase 1.
