Nightfall bridge to Prophecy?

Hey,
I heard that at a certain point in the Crystal Desert,your character could take a "bridge" to the Bone Palace/Desolation area,is it true?
If yes, let say my Ranger takes the "bridge" to Bone Palace/Desolation,does that mean he can start doing missions from this point of Nightfall?

Ok, re-edit...it's throught the Arid Sea

Quote: Requirements to travel:

* Your account must have keys to both the Prophecies and the Nightfall campaigns.
* Travel from the Arid Sea to the Crystal Overlook requires completion of Gate of Desolation mission.
* Travel from the Crystal Overlook to the Arid Sea requires completion of the Sanctum Cay mission. So basically no

basically if u have had a character to Crystal overlook and to arid sea he can then cross between the 2 areas.

The shortcut only works for characters that went the long way to each location first.
