GPS Said Cross the Bridge. The Bridge Had a Giant Hole In It.

A car navigation system led a driver straight to an overgrown, off-limits bridge with a gaping hole in the middle.

What's going on

Car navigation systems rely on map data that can lag years behind reality. When roads are damaged by floods, earthquakes, or simple neglect and quietly taken out of service, GPS databases don't always get the memo — and your nav just keeps routing you there anyway.

A driver in Japan recently shared photos of where their navigation confidently led them: a completely overgrown bridge with a gaping hole through the road surface and no-entry signs posted at the entrance. They were approaching from the far side, so the hole wasn't immediately visible. The only warning was that the bridge looked deeply wrong — abandoned, swallowed by weeds. They slowed down, looked closer, spotted the signs, and turned back.

The post spread quickly, partly for the photos, and partly because of a line that appears in standard Japanese navigation system disclaimers: "Please follow actual traffic regulations." Perfectly reasonable advice. Slightly less reassuring when the system itself is the one routing you onto a condemned bridge.

The bridge my nav told me to cross. What even is this hole… “Please follow actual traffic regulations” is working overtime right now.
If you’d been routed here at night, that could’ve been really bad 😱 So glad you’re okay…!
Thank you ✨ I was approaching from the road on the far side, so I couldn’t see the hole at first — the bridge just looked so overgrown and wrong that I stopped for a closer look, and that’s when I spotted the no-entry signs. Yeah, at night it would’ve been a completely different story 😅
This reads like a ghost story…
Classic horror setup. Follow the GPS blindly at night, fall through the hole, and somehow end up in a village that was supposed to have vanished decades ago…
In a Miyazaki film, crossing this bridge would set something in motion. (Hayao Miyazaki, director of Studio Ghibli films like Spirited Away, is known for stories where crossing a forbidden threshold pulls you somewhere you can’t come back from.)
“Please cross the hashi.”

In Japanese, hashi (はし) is a homophone for three different words: 橋 (bridge), 端 (edge/end), and 箸 (chopsticks). The tweet imagines the GPS politely instructing you to cross “the hashi” — it just never specified which one.

A GPS running on Ikkyu-san logic is terrifying. (Ikkyu-san is a beloved figure from Japanese folklore and a popular anime character, famous for finding hilariously literal loopholes in impossible instructions.)
There’s literally a bit like this in Indiana Jones and the Last Crusade.
It’s like the disappearing magic ball slot on those old baseball board games. (A classic gimmick in traditional Japanese tabletop baseball games where the ball drops through a hidden hole in the pitching area, making it physically impossible to hit.)
Quite literally a pitfall.
The GPS: “I hate perceptive kids.” (A famous line from the anime Fullmetal Alchemist, delivered by Roy Mustang when someone figures out his scheme before he wants them to.)
Feels like a flag just triggered and the route you were never supposed to unlock… unlocked. (In Japanese internet slang, “flag” (フラグ) is borrowed from video game mechanics — a narrative trigger, usually signaling something bad is about to happen.)
Fully autonomous driving vs. bad GPS routing — can it arrive, decide this is impossible, back out, and find a new route? That’s the real test.
So it’s not just mine. Mine routes me through roads that clearly weren’t meant to be driven.
Total kōdō territory. (酷道, read kōdō, is a pun on 国道 (national highway) — swapping 国 “nation” with 酷 “terrible/harsh.” It’s an affectionate term among enthusiasts of Japan’s notoriously narrow and harrowing back roads.)
Yeah, you really can’t just hand your trust over to GPS completely.
Map data just… extremely out of date…?
It happens when the nav is running on old info. I get routed somewhere that makes no sense sometimes too, so when something feels off, I just ask Google-sensei.
Apparently there are still quite a few prefectural roads in disaster-affected areas that were never repaired — and they’re still sitting in the database.
I’ve been directed to a bridge in Kumamoto that collapsed in the earthquake. (The 2016 Kumamoto earthquakes caused widespread structural damage across the region, including bridge and road collapses that haven’t all made it into updated maps.)
This reminded me of that incident where a GPS directed someone to cross a decommissioned bridge, they couldn’t see it in the dark, and drove straight into a pond. Happened overseas, a while back.
The road authority should have that blocked off.
“Please follow actual traffic regulations.” Love that.
Is there seriously no way to report “this road is impassable” anywhere?
You can report it to the Ministry of Land, Infrastructure, Transport and Tourism via LINE and they’ll get it updated. (LINE is Japan’s dominant messaging app; government agencies including national ministries maintain official accounts on it for public inquiries.)
This convinced me not to drive unfamiliar mountain roads at night just because I have GPS and headlights 😰

My take

Navigation is genuinely useful — but it'll confidently route you down something baffling without a second thought. Good reminder not to hand your judgment over entirely.
