Kachidokibashi over the Sumida River.
This is Japan's first Futaba jumping bridge completed in 1940 (1940).
In the past, it opened and closed five times a day, and a large ship sailed under it.
Now, the traffic volume of cars has increased, and the bridge has no longer opened at the end of 1970 (1970).
Kachidokibashi, built with the best of the state-of-the-art technology at that time, has the largest movable branch in Japan.
It has been designated as a national important cultural property as a highly technically complete structure.
Inside the pier, the facilities as it was at the time when the bridge was opened and closed are preserved, and tour tours are available.
It was carried out, but due to repair work of bridge, from January 2018 to the end of March 2020
The tour will be temporarily suspended due to schedule.
So this time, I would like to introduce the situation when I participated in the tour in November.
First, gather at the museum in Kachidokibashi and participate in the Tokyo Metropolitan Construction Disaster Prevention Volunteer Association.
I went to the bridge for guidance.
Kachidokibashi has crossed many times, but he knew and didn't know.
I taught you a lot.
A traffic light that stopped pedestrians when the bridge opened.
The brass gold stud was a stop line for pedestrians.
The center of the bridge. From here, I opened it in the shape of "C".
The traffic lights lined up vertically toward the river are for ships.
This tower is the driver's room. You can see the bridge from the place where you were actually opening and closing.
I did it. There are four towers on the bridge, and the rest of the driver's room is used as a night shift room, a watch room, and a warehouse room.
I wasn't there.
After the driver's room, I moved to the machine room in the pier.
Use a safety belt to descend a ladder of about 3.5m vertically into the pier.
The mechanical equipment of the bouncing section left in the machine room was technically improved by the Japan Society of Mechanical Engineers in August this year.
It has been selected as a historically significant "mechanical heritage."
Please refer to this page for a tour of the driver's room and machine room.

It is not a generation who knows when Kachidokibashi was opening and closing, but explanations while looking closely at the facilities up close.
When I heard it, I saw Kachidokibashi jumping up.
The tour inside the pier during the year is full and the reception has been closed.
You can't visit for a while, but the time required to have Kachidokibashi live longer.
That's right.
If you are interested in Kachidokibashi, please visit the museum in Kachidokibashi.
This museum is a substation that sent electricity to the motor on the pier to open the bridge.
It was renovated and opened to the public.
The power generation facilities that operated the bridge are preserved and displayed, and a model that reproduces the opening and closing of the bridge.
There are plenty of materials such as videos and panels.
