bridge (263 pts)

The bridge that the train passed over in this video was replaced after it was damaged in one of the disasters. A document shows that structures from other bridges were diverted during the replacement.

What is the name of the bridge from which it was diverted? (NOT the name of the bridge in this video.)

Flag Format: Diver25{The name of the bridge in Japanese} Example: Diver25{日本橋川橋梁}

Hints:

• The flag doesn't contain the train line name such as 山手線 (Yamanote line).

• OCR of kanji characters is sometimes inaccurate. If you're confident in your answer but it's marked incorrect, try another OCR tool.

• The word "bridge" may appear as "橋", "橋梁", or "橋りょう" in Japanese.

• Documents in Japanese might describe years using regnal years. For example, 2025 is 令和7年 (Reiwa 7).

Knowledge in Japanese was very helpful in solving this challenge :)

At the beginning of the video, we can see this building with some Kanji 園芸資材 千歳農園 written in it.

This is what the Kanji means according to GPT.

Basically, only the second part 千歳農園 matters, so we can search that on Google and expect relevant results.

The search pointed some places in the Kyushu island, but with a quick brute-force checking, we can get the correct place. And with that, we also get the train line and the bridge.

By looking at the street view near the bridge, we are able to get the name of the bridge: 第二白川橋りょう.

Then, search a document related to this bridge using Google Dorking with the query: "第二白川橋りょう" filetype:pdf . We are able to get this document. On the page 32 of the PDF, there is an explanation that the bridge was repurposed from Tamagawa Bridge (澱川橋梁).
