State Highway 7 is a 150.5-mile (242.2 km) highway in southern Oklahoma. This lengthy highway connects many towns in Oklahoma's "Little Dixie" area. It runs from Interstate 44 in Lawton to U.S. 69/US-75 in Atoka.

Interstate 44 (I-44) is an Interstate Highway that runs diagonally through the U.S. state of Oklahoma, spanning from the Texas state line near Wichita Falls, Texas, to the Missouri border near Joplin, Missouri. It connects three of Oklahoma's largest cities: Oklahoma City, Tulsa, and Lawton. Most of I-44 in Oklahoma is a toll road. In southwestern Oklahoma, I-44 is the H. E. Bailey Turnpike and follows a diagonally northwest–southeast direction. From Oklahoma City to Tulsa, I-44 follows the Turner Turnpike. As I-44 leaves Tulsa, it becomes the Will Rogers Turnpike to the Missouri border. In the Lawton, Oklahoma City, and Tulsa metropolitan areas, I-44 is toll-free. In Oklahoma City, I-44 is also known as the Will Rogers Expressway.
