Introduction of Junction in Chuo-ku: Ryogoku JCT / Kanda Bridge JCT

Two years ago, I discovered that Chuo-ku is the city with the most junctions (7 places) in Japan, and introduced Edobashi JCT and Hakozaki JCT, which are particularly famous junctions in the city. . And as a sequel, in an article a year ago, I introduced three junctions surrounding the city of Ginza.

Today, I would like to introduce the remaining two junctions as a further sequel.

The first is the junction between the two countries.
At the border between Chuo-ku and Sumida-ku, it is a junction in which the Metropolitan Expressway Route 6 (Mukaijima Line) heading for Joban Expressway and Metropolitan Expressway Route 7 (Komatsugawa Line) heading for Keiyo Road diverge. Most of them are located above the Sumida River as "Ryogoku Ohashi". Therefore, you can see the junction well from the Sumida River terrace on both banks.

The structure is also characteristic because of the unusual situation that crosses the river while branching.
One of the most interesting things is the hanging structure. On the left side of the photo, do you see a thin line connected from the upper bridge girder to the lower bridge girder? In fact, this is a structure in which the upper bridge girder lifts the lower bridge girder.

Finally, I would like to introduce the Kanda Bridge Junction.
This is the border between Chuo-ku and Chiyoda-ku, and is a junction where the Metropolitan Expressway Yaesu Line (Y) branches off from the Tokyo Metropolitan Expressway Toshin Beltway (C1). Most are located in Chiyoda-ku, but slightly hides Nihonbashi Honishi-cho, Chuo-ku. (Because it is a branch-type junction, it is difficult to determine how far the junction is used.…。)

The Toshin Beltway runs over the Nihonbashi River, while the Yaesu Line runs underground such as Sotobori-dori St.…This means that the Kanda Bridge JCT, which is the junction, is designed so that the Yaesu Line lanes dive into the Nihonbashi River.
The figure can be seen well from the Ryukan Sakura Bridge, a pedestrian-only bridge connecting Otemachi and Honishimachi across the Nihonbashi River.

What is the future of the junction number ranking?…?

What is the future of the junction number ranking?…? Introduction of Junction in Chuo-ku: Ryogoku JCT / Kanda Bridge JCT

Well, there is a reason why I hurried to make this article in March.

According to press releases of Tokyo Kosoku Doro Co., Ltd. and Metropolitan Expressway Co., Ltd. on February 14, 2025, the Tokyo Kosoku Doro (KK Line) was abolished at 20:00 on April 5, 2025, and at the same time the Metropolitan Expressway Yaesu Line It was announced that it will be closed for a long time until 2035.

Then, at the same time, Nishi-Ginza JCT will be abolished, Shiodome JCT and Kyobashi JCT will no longer be junctions (it will be a lamp heading to Shiodome entrance and Higashiginza exit), so three junctions will be lost at once, even though the trends of other municipalities have not been checked) will lose Chuo-ku seat in this ranking compiled two years ago. Let's introduce all the junctions between the first place in the ranking! That's why I thought it.

I think that a junction will be newly established at the point where the Shinkyobashi connecting route, which will be maintained later, joins the Toshin Beltway, but on the other hand, the junction that will be the successor to Kanda Bridge JCT will be completely within Chiyoda-ku, so the subsequent junction changes will also be plus or minus zero.

Chuo-ku is the largest number of junctions in Japan.…So, please take this opportunity to come to Chuo-ku to appreciate the junction!
