U.S. Forest Service (USFS) is closing three miles of a road in southern Illinois 90 miles southeast of St. Louis for the next month to protect snakes undertaking a biannual migration in the Shawnee National Forest

Great River Road will be closed to motorized vehicles. “Forest Road 345 is the number,” said Vukovich. “Everybody knows it as Snake Road. It’s just a great place to come watch snakes.”

“The number 1 snake you’re going to see here is going to be the northern cottonmouth, the other two venomous snakes are copperhead and timber rattlesnake. You have a good chance of seeing those.”
