The newt – a kind of salamander five to six inches long – takes it easy in a dormant state during the dry season.
The road will be closed to automobiles Nov. 1 to April 1. Pedestrians and bicyclists may still use the road but are asked "to proceed slowly and carefully to avoid newts crossing the road," Tilden Park Supervisor Sergio Huerta says on the park district website.
You also shouldn't touch the newts or allow your dog to touch them.
"They have a substance on their skin that is mildly poisonous to people and other animals," according to the park district. "If you accidentally come in contact with a newt you should always wash your hands."
