Osceola Parkway, signed as County Road 522 (CR 522) since around 2003, is a 17.5-mile-long (28.2 km), partially tolled arterial road extending east–west across the northern boundary of Osceola County, Florida, roughly paralleling the border with Orange County. It connects Walt Disney World with Interstate 4 and Florida's Turnpike before terminating at Simpson Road near Buenaventura Lakes, and is maintained by Osceola County. Only the section between the Southern Connector and a toll plaza east of Shingle Creek is tolled; the rest includes mainly at-grade intersections. A portion of the Osceola Parkway was once called Dart Boulevard.
