This highway is said to be haunted by two headless ghosts. One is a construction worker who was working to build the highway. He was robbed and murdered by a fellow laborer, and his decapitated body was buried under the road. His ghost is still seen by motorists traveling the highway on a stretch of the road called Deep Cut, which lies between Cambridge and Old Washington.
The other spirit is a woman who lived in a cabin near the old trail in the late 1890s. She was beheaded by her husband during a violent argument. Soon after, her headless apparition was seen riding sidesaddle on a white horse. She has come to be known as Lady Bend. Lady Bend is seen on the highway at Lady Bend Hill on the third bend from the top.
