The Quarry Access is a room in the Phazon Mines. It connects the Transport to Tallon Overworld South to the Main Quarry, both by Purple Doors. The room is a small tunnel that has a floor coated with Phazon. A large metal structure provides a walkway between the two door. Railings prevent Samus from leaving this metal structure.
- A clicking sound can be heard throughout the room that is similar to the sound that a Geiger Counter produces in the presence of radiation, possibly indicating the high radioactivity of Phazon.
