Osceola Parkway, signed as County Road 522 (CR 522) since around 2003 (and originally planned as State Road 424), is a , 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 (formerly Boggy Creek 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. Route description The road starts at an intersection with an entrance road to the Disney's Animal Kingdom Lodge in Lake Buena Vista. For its westernmost , it has many characteristics of an at-grade boulevard; however, east of the entrance to Disney's Animal Kingdom, it becomes a grade-separated expressway. Heading east, the parkway passes through several sections of the Disney World Complex before intersecting with World Drive and crossing into Osceola County. The parkway exits Walt Disney World, just before an interchange with I-4. Although Osceola Parkway was built across I-4 into Walt Disney World, an interchange with that freeway (Exit 65) did not open until 2001. The ramps with the exit to nearby SR 536 are interspersed such that traffic going on to I-4 from SR 536 cannot directly exit onto Osceola Parkway, and vice versa. The road then has an interchange with SR 417 (Southern Connector), where the Parkway becomes a limited access toll road (although not a full expressway). The parkway passes through residential areas, passing through an interchange with Poinciana Blvd., featuring ramp tolls of $1.00 for eastbound exiting traffic and westbound entering traffic. East of the interchange, Osceola Parkway crosses the one mainline toll plaza just east of Shingle Creek, with a $2.00 toll as of January 2020. East of the toll plaza, the tolled section of the parkway ends as it becomes a surface street, as it continues to pass through residential and shopping areas with at grade intersections, most notably with John Young Parkway and US 17/US 92/US 441 (Orange Blossom Trail) as the road heads towards Florida's Turnpike. East of the Turnpike, the road continues as a four lane street through another residential development until its terminus at Simpson Road, near Buenaventura Lakes. Simpson Road was known
