Thorn Creek Woods Nature Preserve's pedestrian bridge over Thorn Creek is closed until further notice due to structural safety concerns. 

As a result of the bridge closure, the Woodland Trail, Owl Lake Trail and Wetland Trail also are closed until further notice.

The half-mile Thorn Creek Nature Center Loop Trail remains open to the public and scheduled naturalist-led programs will be available. 

Closure signs and maps have been posted at the trailhead kiosk, in the nature center and on the trails, alerting hikers to the areas that are now closed in the preserve.

The nature center is open to the public on Fridays from noon to 4 p.m. For more information or to register for programs, contact Thorn Creek Nature Center, 247 Monee Road, Park Forest, 708-747-6320, email [email protected] or visit the website.
