"Overview of Dansho Bridge and Former Dansho Bridge" is as follows.
Danjobashi: : It is located on Kajibashi Street, 2-3-chome, Kyobashi. In 1913 (1913), it was erected upstream of the former Dansho Bridge (Kaedegawa).
Moto Danjobashi (former Danjobashi) ：The name of the bridge was described as a name bridge in the Kanei era, Shoo era, and Meiryaku era, "Togoehashi" in the figure of 1700 (1700), and later it became Bunsho Bridge. It is derived from Shimada Dansho Kosuke, where mansion was located in Hatchobori (former Matsuyamachi) east of this bridge. In 1913 (1913), Dansho Bridge was erected upstream of Moto Dansho Bridge, so it was renamed Moto Dansho Bridge and survived, but was abandoned due to land readjustment. In Tokyo City, since this bridge was Japan's first domestic bridge, it was relocated and preserved as Hachiman Bridge at its current location (Koto-ku) in May 1929. The bridge was first built in 1878 (1878) by using domestic cast iron and steel. It was designated as a national important cultural property in 1977 (1977). 1989 (1989) Received the Honor Award of the Civil Engineers of the United States for the first time in Japan.

Overview of Walking:
Walking through Kajibashi-dori, Eitai-dori St. to the destination heading east (the nearest station: departure starts at Takaracho Station on the Toei Asakusa Line, and the terminal ends at Monzennakacho Station on the Tokyo Metro Tozai Line and Toei Oedo Line)
From Toei Subway Takaracho Station, go east along Kajibashi Street to the current Dansho Bridge. There is a symbolized model of the former Dansho Bridge in the park on the left (north side), and a monument of Dansho Bridge installed by Chuo-ku in the park on the right.
Soon on the left, at the corner of Keika Square, there is an explanation board of the "Monoshiri Encyclopedia" p59 14 Hatchobori's power and concentric mansion. Go straight and cross Yaesu Street at Shinkawa 2-chome. I think this is around the southwestern side of the former Echizen moat. Cross to the right side of Kajibashi Street (in the direction of Chuo-ohashi Bridge) and proceed toward Eitai Bridge.
A little before the Eitai Bridge West Signal, a narrow road between the first gas station on the right and the building in front of it, seems to be the trace of Shinkawa. At the end, you can see Shinkawa stone monument p5777 in the distance. In addition, go through Kajibashi Street to Eitai Bridge. There is a monument of p565 seafarer education in Hashizume.
Cross the Eitai Bridge (important cultural property: current extension of life and the sidewalk is narrow) to Koto-ku side. From the bridge to the lower reaches of the Sumida River, the high-rise house on Ishikawajima, Chuo-ohashi Bridge, towers beautifully. There is an explanation board of Eitai Bridge (important cultural property) on Hashizume on the east bank.
Walk east on Eitai-dori St., turn the sidewalk to the north side of Eitai-dori St. at the traffic light on the way, and proceed east. Cross Kiyosumi-dori while checking the sideways at Monzen-Nakamachi Station, go straight ahead, go north on the east side road of Tomioka Hachimangu Shrine to the east gate, turn right andpromenade Yahatabori on the left. When you enter promenade, you can see Hachiman Bridge in front. There is an explanation monument near the bridge.
When I saw Hachiman Bridge, what I noticed was that the width was narrow. The monument in Chuo-ku at Danshobashi, the starting point, is 9.0m wide. However, the local explanation board is 2.0m (also the real thing). (There is a slight difference in length.) For these, Rio Suzuki is written in Nos. 119 and 120 of "News from Local Room". It seems that renovation was carried out when the former Dansho Bridge was installed as Hachiman Bridge at the current location.
On the day when I saw Hachiman Bridge for the first time, I saw the energetic elementary school students crossing the school, and the oldest iron bridge (important cultural property) in Tokyo more than 130 years ago was used quietly and quietly. I felt the splendor.
The bulldozer told the observation deck

The Rainbow Bridge and the night view around you will make you feel very romantic. observation deck's summer opening hours are until 20:00. It is convenient because the Toei bus
