The Will Rogers Turnpike is a freeway-standard toll road in the northeast portion of the U.S. state of Oklahoma. The highway begins as a continuation of the Creek Turnpike in Tulsa, continuing northward from the I-44/US-412 interchange there to the Missouri state line west of Joplin, Missouri. The turnpike carries the I-44 designation for its entire length. The turnpike is long and costs $4 to drive one way. The Will Rogers Turnpike opened to traffic on June 28, 1957. It was designated as I-44 in 1958. It is named for Will Rogers, "Oklahoma's Favorite Son".
