Alternate routes and closures for Starved Rock Marathon due to Illinois River rising

The Starved Rock Marathon will be occurring this Saturday, May 11th. The park road will be closed to traffic from 7:20-7:45 a.m. The eastern canyon parking lots at Illinois, Ottawa, and Kaskaskia will be closed during the marathon.
Due to the heavy rains earlier this week the Illinois River is rising again and Dee Bennett Road may be unsafe for runners. Because of this, a decision was made to use the alternate route for the safety of everyone.
