The Audubon Parkway is a four-lane controlled-access freeway (formerly a toll road) connecting the cities of Henderson and Owensboro, Kentucky. Named for John James Audubon, an early American naturalist, the Audubon's western terminus is at US 41; the eastern terminus is US 60. The road opened on December 18, 1970, at a cost of $23.5 million (equivalent to $123 million in 2020) and, at 23.4 miles (37.7 km), is the shortest of the seven roads in the state's parkway system. It is also the only road in the parkway system that has not had the name of a Kentucky politician attached to it. The road carries the unsigned designation of Kentucky Route 9005 (KY 9005). A white and gold shield was used along the Audubon Parkway until 2006, when a new, standardized blue-on-white marker was introduced f
