Interstate 44 (I-44) runs diagonally through the US 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 north–south 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 metro areas, I-44 is toll-free. I-44 is paralleled by former U.S. Highway 66 (US-66, now mostly State Highway 66 (SH-66)) from Oklahoma City to the Missouri state line. In Oklahoma City, I-44 is also known as the Will Rogers Expressway. Route description I-44 crosses the Red River near Burkburnett, Texas. It is toll-free until exit 5, which is the last free exit before the start of the southern section of the H. E. Bailey Turnpike. At exit 30, the tolls end, and I-44 becomes a non-tolled highway again through Lawton and Fort Sill until exit 46. The northern section of the H. E. Bailey Turnpike carries I-44 north, serving Chickasha before ending at US-62 (exit 107) in Newcastle. From Newcastle, I-44 heads north through rural parts of Oklahoma City before serving as the western terminus of I-240. It then indirectly serves Will Rogers World Airport by connecting to Southwest 59th Street (which becomes Southwest 54th Street before reaching the airport) and SH-152, the Airport Road freeway. I-44 meets I-40 west of downtown at an interchange sometimes referred to as the Amarillo Junction. I-44 then passes west of the state fairgrounds and continues north to provide access to Bethany and Warr Acres. It then turns more eastbound before reaching a junction with I-235, which also signifies the northern end of I-235, and US-77 also known as the Broadway Extension, which connects Downtown Oklahoma City to Edmond. It then meets and follows a stretch of I-35, which it overlaps with until the Turner Turnpike interchange, where it takes an easterly turn again. I-44 then follows the Turner Turnpike to Sapulpa, where it becomes a non-tolled road after meeting SH-66. I-44 bypasses downtown Tulsa; I-244 serves the downtown areas. After meeting the Creek Turnpike again on the eastside of the city, I-44 becomes a turnpike once again, gaining
