Things are never easy for the town in My Time At Sandrock. Thanks to the Geegler President and his nefarious plan-gone-wrong, the main bridge in Sandrock is broken. Without the bridge, Sandrock is effectively cut off from other cities, and it’s up to you and your fellow builder Mi-an to help repair it.
Repairing the bridge is a long and complicated process, and you’re going to need a lot of materials and some dungeon-diving to find what you need for it. We’ll show you how to find all the materials, where to find a Power Core, and even how to fight a giant robotic cat.
How To Build The Bridge Trusses
Repairing the railway bridge involves several steps within the main quest In Trusses We Trust, and solving three additional quests during it: Paradise Lost and Found, Qi’s Gungam Opus, and The Inspector.
Special commissions will also appear at the Commerce Guild from Heidi for bridge materials. These don’t count towards your daily commission limit and reward more Gols than usual commissions.
This quest becomes available after witnessing the Fireside Meeting on the next Sunday after completing Belly of the Beast and defeating the Geegler President.
Your first task in this quest is to build two Trusses for the bridge, each of which requires three materials: Bronze Frames, Steel Bars, and Copper Screws.
Truss Material |
Machines Needed |
How To Obtain |
---|---|---|
Bronze Frame x6 |
Intermediate Worktable |
Crafted from Bronze Bars and Bronze Rivets at an Intermediate Worktable.
The Intermediate Worktable can be unlocked by researching the design from Qi or at the Research Machine in his lab. |
Steel Bar x16 |
Civil Recycler and Civil Furnace |
Crafted from Iron Ore, Graphite, and Dinas in a Civil Furnace.
|
Copper Screw x40 |
Grinder |

Once you’ve got both Trusses, head over and speak to Heidi. She’ll accept them and tell you that you’ll need to wait a little while since repairs are going slow.
How To Navigate Paradise Lost Ruins
The next day after talking to Heidi about the completed trusses, Qi will send you a letter in the mail.
He thinks there might be a Power Core in the Paradise Lost Ruins, and with it, he might be able to speed up the bridge’s repair process.
Similarly to other dungeons in the game, you’ll want to bring along some healing items like Yakmel Milk, and you’ll want to have ample inventory space.
Head to the Paradise Lost ruins next to Eufaula Salvage, and meet up with Justice and Unsuur at the gate to the ruins for a short cutscene. With the door fixed by Mi-an, you’ll be free to go inside Paradise Lost and explore.
On the path down, you’ll be fighting several enemies, such as Trotters and Sweepers, and there are several extra buildings and caves for you to enter with crates to destroy, and Treasure Chests that you will need to clean off with a Feather Duster.
How To Find The Orange Mall Key
Make your way down to the bottom, and enter the Paradise Ruins. The first section is two large areas full of junk, two Damaged Sweepers to fight, and one treasure chest partially hidden by mine-able dirt near a fence.
You can begin to get Iron Ore from the dirt inside these ruins, so make sure to dig them up.
Walk up the broken yellow tunnel to the second floor, then curve around through the room with two Trotters, two Sweepers, and a Disgruntled Security. There will be a second treasure chest against the first pillar with a robot sign on it.
Go across the bridge, then head up the wooden platforms to the left, bypassing the interactable console by the door. There’s also a third treasure chest on a platform reachable using the thin wood beam.
Follow the path around, grab the Orange Mall Key, then head back to the console and interact with it to unlock the door.
Make sure to grab any of the tiny Junk Piles, as each one can contain a useful material such as Graphite or Engines.
Fight through the next curved room, grab the treasure chest sitting on one of the benches against the wall, and make sure to grab the Small Blue Key 1 off the metal structure on your right as you go through.
Take the ramp back down, and you’ll begin to run into both Hauler and Damaged Haulers on the bottom floor. There’s also going to be another treasure chest against the back wall near a Damaged Hauler.
Next, head past the Damaged Sweepers and through the corridor using the broken train cars.
How To Find The Yellow Mall Key
The path to the right wraps around to a dead end with a Damaged Hauler and another treasure chest. After you get the chest, head back around and take the left path, wrapping around to a corridor lined by blue chain fences. There will also be a treasure chest in a single train car behind you.
Head through the next train car and out to another area with a Trotter, a Disgruntled Security, and a Hauler. Defeat them, then head around to the stairs blocked by a Damaged Hauler.
At the top of the stairs you’ll have another console and locked door, and you’ll need to wrap around to grab the key again. Head to the right over the wooden bridges, grab the Yellow Mall Key off a broken robot, and then follow the path back down to the bottom floor and around until you’re back at the console.
How To Find The Purple Mall Key
Use the Yellow Mall Key, and walk into the next room. There will be one Sweeper near the door, and an exit on the right side of the room next to a Healing Station, and a treasure chest.
Ignore the exit for now, grab the chest and heal up and save if you need to. Grab the Small Blue Key 2 from a shelf in the corner, fight the next Sweeper and Disgruntled Security, and then continue around.
Defeat the Hauler and two Disgruntled Security across the bridge, then head down the ramp to the bottom floor again where you’ll have to fight two Haulers and another Disgruntled Security.
The Purple Mall Key you’ll need next is in the left corner of the room, sitting on a set of blue transportation chairs. Go back up to the bridge and interact with the console to open the next door.
How To Find The Red Mall Key
Follow it around, grab the chest in the corner by the chain link fence, and then grab the Small Blue Key 3 from the broken train car. Finally, head back to the bottom floor where the two Haulers and Disgruntled Security were, and you can unlock the console at the large doors with the three blue keys.
Go through the two doors, grab the treasure chest in the corner behind the counter, and then continue up the stairs. The sliding door is where you’ll need to go, but head up one more floor and grab the Red Mall Key from the chairs in the corner before you exit to the next room.
Defeat the two Haulers, then use the Red Mall Key on the console on the wall to open up a room with three chests. Head back to the room, and head up the ramp to the large blue doors.
Use the last Healing Station if you need to and save, then head across the two bridges to the orange door to face the boss.
How To Find The Power Core
The boss you’ll be facing is Control Cat, and it can’t be damaged until you destroy the three control consoles located on each side of the room.
Rotate around the room to the right and destroy the first console, taking care to avoid the electric rod arms. Not only do they do a fair amount of damage and can break your toughness quickly, but they’ll stun you for a few seconds, allowing the boss to get multiple hits on you.
After the first console is dead, the Control Cat will break down, allowing you to get to its back, where you’ll need to attack the open blue port on its back.
Once the first port is destroyed, the Control Cat will wake back up and increase its rotation speed. Heal as you need, then repeat the process for the next two consoles and the next two ports on its back.
Defeat the Control Cat, and you’ll get the Strange Power Core from its body, and several tier-two materials, such as Bronze Plates and Copper Wire. Take the exit in the room, and you’ll be back outside the Paradise Ruins.
With the Power Core in hand, head over to the Research Center, and you’ll get a brief cutscene with Qi. Turns out the core you found is even better than expected, and you’ll need to wait for his results.
How To Build The R-47 Mobile Suit
Check your mail the next day, and Qi will tell you he’s had a breakthrough, so head on over to the Research Center.
Go inside, and you’ll get a brief scene with Heidi and him, and he’ll tell you about his key to building the bridge quicker: a mobile suit.
To make the R-47 Mobile Suit, you’ll need five materials: Simple Circuits, Rubber Shells, Steel Bars, Old Parts, and the Strange Power Core you got from the Control Cat.
R-47 Mobile Suit Material |
How To Obtain It |
---|---|
Simple Circuit x3 |
Found when excavating relics in Eufaula Salvage Abandoned Ruins on layers seven or below. They can also be found occasionally when opening Basic Toolboxes found within layers seven or below in the Eufaula Salvage Abandoned Ruins. |
Rubber Shell x3 |
Crafted from Rubber at a Processor.
|
Steel Bar x4 |
Crafted from Iron Ore, Graphite, and Dinas at a Civil Furnace.
|
Old Parts x5 |
Obtained from recycling Mechanical Scrap at a Recycler. Old Parts can also be obtained when digging through dirt or excavating relics in Eufaula Salvage Abandoned Ruins. |
Once you’ve got the mobile suit crafted, head over to the railway bridge and speak with Heidi. She’ll thank you for the suit and tell you that the bridge base will be ready in two days.
How To Make The Magneto Inductive Inspector
One day after giving Heidi the mobile suit, the bridge’s inspector will arrive, and you’ll get a brief cutscene with a quick-time event involving him.
After the scene, bring Mint over to the City Hall, and you’ll find out he’s forgotten the tool he needs to actually inspect the bridge, the Magneto Inductive Inspector, and you’ll need to build him one.
Wait one more day, and you’ll get the diagram in your mailbox. The Magneto Inductive Inspector needs three materials: Glass Lens, Rubber Shells, and a Bronze Frame.
Magneto Inductive Inspector Material |
How To Obtain It |
---|---|
Glass Lens x2 |
Crafted from Glass and Bronze Pipes at an Intermediate Worktable.
|
Rubber Shell x3 |
Crafted from Rubber at a Processor.
|
Bronze Frame x1 |
Crafted from Bronze Bars and Bronze Rivets at an Intermediate Worktable.
|
Once you’ve got the Magneto Inductive Inspector, bring it to the Mint on the ridge overlooking the bridge, and you’ve just gotta wait one more day.
How To Repair The Railway Bridge
The next morning after delivering the inspector to Mint, you’ll automatically teleport to the bridge site after exiting your home.
Take the two trusses, and install them on each end of the bridge, and you’ll finally have the bridge repaired.
Speak to Heidi and Mi-an, and you’ll get a pretty hefty set of rewards for your help: 2,000 Gols, 2,100 Experience Points, 15 Relationship Points with Heidi, 40 Workshop Reputation, and a perfect quality Froggy Explorer Vest.
