Construction, Closures and Controlled Burns

Preserve improvements, construction projects and weather-related events sometimes result in temporary detours or closures of trails, preserves or facilities to ensure public safety.

Emergency alerts, closure notices, construction alerts, controlled burn locations and preserve planning projects are provided on this page and updated during normal business hours, 8:30 am–5 pm, Monday–Friday, excluding holidays. Project updates are sometimes also provided on Facebook and Twitter.

Trail and Underpass Status

Check the current status (open/closed) of trails and underpasses along the Des Plaines River Trail, the Millennium Trail, community trail connections, and preserve trails marked on the map below. Public access is restricted at closed trails and underpasses. Please follow preserve and trail signage and use caution around closures, construction or detour zones. The map below works like many other online interactive maps.

Public Access Prohibited

Respect blockades and closure signage. Do not move blockades or attempt to access closed areas.

Ethel's Woods Forest Preserve––CLOSED: This preserve is closed for construction and unsafe for public access. We are restructuring the earthen dam to slowly drain 53-acre Rasmussen Lake and restore the North Mill Creek stream channel. A deep sediment layer will be exposed during restoration, making the area unsafe. Posted Aug 14, 2014. 

Fort Sheridan Forest Preserve––CLOSED: Portions of Fort Sheridan Forest Preserve are closed as construction. Public access improvements for Fort Sheridan were approved by the Lake County Forest Preserve Board in November 2015 as part of the Master Plan for the preserve.

Restoration Work

Fort Sheridan Forest Preserve | Lake Forest

Invasive Plant Removal Project

Through 2017, crews will be removing invasive woody and herbaceous plants throughout the preserve. This project is the implementation of the U.S. Army Corps of Engineers Great Lakes Fish and Ecosystem Restoration program.

Questions, comments, updates? Call or email Army Corps Public Affairs Office, 312-846-5330.


Woody Invasive Species Clearing Project

Through winter 2016–17, our well-trained crews will remove invasive woody species, primarily buckthorn, autumn olive, sandbar willow and honeysuckle, from the preserves throughout the county. Clearing will be completed through the use of hand tools and mechanical equipment. Brush and small trees will be burned in brush piles under carefully controlled conditions. The majority of the clearing work will occur during the winter months when the frozen ground conditions prevent disturbance to the soil, native plants and wildlife. Learn more »

Trail Work

Everett Road Trail Connection

Approximately 0.85-miles of paved hiking and biking trail is being added to Wright Wood’s northeast trail loop, connecting the trail to Everett Road. While no trails will be closed during the construction, please use caution, slow down, and look for signs and work crews along the way. Construction is scheduled to be complete by fall of 2017.

Major Conservation Initiatives

Various Preserves Across Lake County

Lake County is home to more endangered and threatened species than any other county in Illinois. We are actively working to restore the habitats that our native wildlife and plants need to survive and thrive.

Check our Conservation Projects page for information about natural resource projects happening in preserves across the county.



Off-Leash Dog Parks

Planned Improvements

If dogs could talk they would no doubt tell us they love living in Lake County. What’s not to love, with four great dog exercise areas and a new one on the way? Good news for our lucky canines is that these romping grounds will get even better over the next several years.


Controlled Burns

Every spring and fall, our ecologists burn hundreds of acres throughout Lake County. Controlled burns are considered a natural resource manager’s most cost-effective tool available for managing natural communities. Learn more »
