Transport Access is a room in the Phazon Mines. It appears in Metroid Prime. It is a long tunnel smothered in raw Phazon in the Phazon Mines on Tallon IV. Before the Phazon Suit is collected, Samus can cross the tunnel using her Grapple Beam. If the room is entered before Grapple Beam is collected, there will be floating platforms to allow Samus to cross.
- The White Door leading to Phazon Processing Center can be opened with the Phazon Beam (via hacking) and only from this side.
