Warrenville, IL – Visitors heading to the Blackwell Forest Preserve today should prepare for access changes as the maintenance roads on the Blackwell Landfill, also known as Mt. Hoy, will be temporarily closed for regrading work.
According to the Forest Preserve District of DuPage County, the East Road and South Road on Mt. Hoy are scheduled to close Tuesday, Nov. 25, for a full day of grading. The project is part of the Forest Preserve’s fall maintenance cycle, aimed at improving road stability and drainage across the landfill’s steep terrain. Officials noted that all work remains weather dependent.
The closure affects two internal service roads:
• East Road – approximately 1,308 feet long and 8 feet wide
• South Road – approximately 1,055 feet long and 8 feet wide
Both routes are represented in an updated site map released by the district, showing the temporary shutdown impacting access around the landfill ridge and nearby areas of Silver Lake. While the roads are primarily used for maintenance and operational access, visitors may notice equipment, shifting access points, or minor delays near Mt. Hoy’s base.
The Forest Preserve District said crews will work to complete the grading by the end of the day, but weather conditions could push work into later in the week if rain or freezing conditions occur. The improvements are intended to prepare the site for upcoming winter operations and long-term preservation work scheduled into 2025.
Visitors planning hikes, sledding prep visits, or trail use near Silver Lake are encouraged to use caution around posted work zones and follow all signage.
