The Bridge Ranger Outpost is a hidden lab in Grounded 2 that you reach by swimming through a flooded tunnel rather than walking up to a sprinkler like most outposts. Inside sits the Steamed Science research item and a Pneumatic Transit System fast travel point, but the route runs through a spider-filled cave and a pocket of toxic gas. The entrance is tucked near the Bridge area, close to Shunk Pond, at coordinates -38° N / 22° E.
Quick answer: Equip a Diving Helmet, dive into the water at -38° N / 22° E near the Bridge, swim the underwater tunnel, put on a Gas Mask when you surface in the gas cave, climb past the Toe Biter Nymph, open the locked door with a SCA.B 2K Scanner, then pay 700 Science at the PTS station to unlock fast travel.
Gear you need before you go
The swim to this outpost is long, and the cave on the other side will start draining your health the moment you climb out of the water. Bring both pieces of protection below or you will not survive the trip.
| Item | Why it is required |
|---|---|
| Diving Helmet (or Koi Helmet) | Lets you breathe during the long underwater tunnel swim. |
| Gas Mask | Stops the toxic “Woozy” effect inside the gas-filled cave before the lab. |
Tip: The tunnel is home to Diving Bell Spiders, and a Toe Biter Nymph waits near the lab entrance. Neither has to be killed, so you can swim and climb past both if you would rather save your supplies.
How to reach the Bridge Ranger Outpost
-38° N / 22° E. Open your inventory and equip the Diving Helmet in your Head slot so you can breathe underwater.
Activate the fast travel station for 700 Science
The outpost includes a Pneumatic Transit System (PTS) fast travel station. Find the terminal and pay 700 Science to power it on. Once active, the Bridge outpost appears on your fast travel map, so you can hop straight here later without repeating the underwater swim.
You will know it worked when the fast travel map opens with the Bridge outpost added as a selectable destination. If the station does not respond, you are short on the 700 Science cost. If the “Woozy” meter is climbing while you stand at the terminal, your Gas Mask is not equipped.
With the station online and the Steamed Science note collected, this hidden lab becomes a fast, safe waypoint for exploring the Bridge and Shunk Pond zones added in Into the Abyss. Keep your Diving Helmet and Gas Mask handy whenever you plan to return by the tunnel route, since the spiders and gas cave are still there even after the outpost is unlocked.
