With demolition beginning in earnest at Disney’s Hollywood Studios for Star Wars land construction, plans are now underway to replace the World Drive vehicle entrance of Disney’s Hollywood Studios with an entirely new entrance guests can utilize off of Osceola Parkway.

According to permits recently filed with the South Florida Water Management District, the intersection between Wide World of Sports and Disney’s Art of Animation Resort will soon be home to exit ramps that will guide guests into the park while making room for the southern edge of Star Wars land at the very boundaries of Disney’s Hollywood Studios. Sections of Osceola Parkway will also be widened to handle the expanded traffic expected.

There is now word yet on if the Buena Vista Drive park entrance would close (or remain open just to buses) once this new entrance was complete, but it appears at the very least the World Drive entrance should be shuttered.

Disney has made no official announcement on the project as of yet.
