Stretching from the heart of Texas to the Gateway City of Missouri, Interstate 44 (I-44) is a major east–west corridor serving the south-central United States. Covering approximately 634 miles, I-44 begins in Wichita Falls, Texas (via a connection with US-277/US-281/US-287), and travels northeast through Oklahoma and Missouri before terminating in St. Louis. Along the way, the highway provides vital connections to several metropolitan areas, including Oklahoma City, Tulsa, Springfield, and St. Louis.
I-44 is notable for following much of the historic route of U.S. Route 66, particularly from Oklahoma City to St. Louis. In fact, many segments of I-44 were built directly over or parallel to the old “Mother Road,” making it a popular drive for nostalgia-seekers and road trip enthusiasts. Remnants of Route 66 culture—like vintage motels, roadside diners, and kitschy attractions—can still be found dotted along the corridor, especially in Oklahoma and Missouri.
The highway serves both commercial and recreational traffic. In addition to urban bypasses and freight-heavy interchanges, I-44 offers access to scenic and cultural landmarks such as the Ozark Mountains, the Meramec Caverns, and Route 66 State Park. Its role in connecting oil, agriculture, and manufacturing centers across three states makes I-44 an essential piece of America’s interstate puzzle.
