As part of the Disney Springs project, construction work has now meant changes to the entrance/exit of Downtown Disney, as well as local road closures.
WDWMagic reports that Entrance 3 is now being used as an exit only (located between the AMC Dine-In Theaters and Planet Hollywood). In addition, the road connecting Entrance 3 to Entrance 4 (behind AMC, Splitsville and DisneyQuest) is now closed to both foot and vehicle traffic, and will remain closed until late 2014, when the new multi-level parking garage will be completed.
Guests on foot can still enter and exit at Entrance 3.
