Nihonbashi Blue Sky Plan: At the time of the last Olympics, "Aerial Operation" was launched. This time, "underwater operation" to dive in water
"I don't allow a smart highway to run over Edo Nihonbashi, the center of Japan," said in 2021, an underground highway plan of about 1.1 km from Edobashi to Nihonbashi to Kanda Bridge Junction began.
Japan was decided to hold the 1964 Tokyo Olympics. The road conditions at that time were extremely bad, and around Edobashi, the average speed was 15 to 25 km / h. A highway is absolutely necessary, but since it takes only five years to hold it, you can't spend time acquiring land. Therefore, it was decided to adopt an "airway road" that passes the road over the river. 57 years later. It is moving from the air to the water.
Since the Edo period, all roads in Tokyo have been built to join in Nihonbashi. Therefore, even if you make it on an old road, you have to join one near Nihonbashi. Even more, if you use the Nihonbashi River, which has a width of only about 50m, the route will be winding. The left end of the photo below is the Nihonbashi Dia Building (Mitsubishi Warehouse Headquarters) located near Edobashi. There is a big bent highway right next to it. The advanced technology cultivated at Tokyo Tower was used to make a 30-meter-long member with a curve without interruption for one minute, and to connect one by one.
The person who worked at Mitsubishi Warehouse, I was surprised that the car ran out of the window at the height of the eyes. "Did you see it?" The driver now, Rolex's watch."
After passing through the Mitsubishi Warehouse, the road curves further and enters Nihonbashi. "It's bad. If this is the case, you will hit the lighting tower of the bridge." I opened the road quickly and avoided the pillars.
A complex upper and lower three-layer structure and three-dimensional ramen structure that surprised the world.
The Edobashi Junction, just east of Nihonbashi, is Japan's first upper and lower three-layer structure. You need 100 piers to support you to pass through the three roads here. However, if you drive in 100, the water of the river stops flowing and overflows the road. Therefore, a "three-dimensional ramen structure" that supports multiple roads with a few piers was adopted. This is the first time in Japan.
The Metropolitan Expressway, which was said to be "I can't do it" or "reckless", was completed nine days before the opening ceremony of the Olympics, and surprised the engineers around the world who visited the inspection. "A complex curved road running over big cities. We can't make it very much," says Rex Whitton, Director-General of the Federal Bureau of the United States. ※Citation project challengers Tokyo Metropolitan Expressway, aerial operation for the Tokyo Olympics
"This is art!" Hakozaki Junction is a sacred place for ironworks and bridges.
Looking up from the police box near the Royal Park Hotel in Nihonbashihakozakicho, seven highway lanes heading to Hakozaki Junction cross each other, and the atmosphere is futuristic. The heavy iron structures of the Edobashi Junction, which are underground, are also overwhelmed by bent or overlapping. Many people come from home and abroad to take pictures.
A toast while watching the beautiful Nihonbashi where the highway lights up!
"Who did you say that the road was blind?" Once, go to a cafe restaurant-style izakaya named "Nihonbashi Ichinoichi Ichinoichi" located at 1-1-1 Nihonbashi. Nihonbashi, which is illuminated by the expressway, will shine and you will be able to feel the beauty of "collaboration of roads and bridges".
From 5:00 to 7:00, the beer and highball are 500 yen. Unfortunately, the terrace seats facing the waterside are thought to be Ann happy without happy hours, and beer is very reasonable at 690 yen. There is no table charge. I'm happy because I can see the nationally designated important cultural properties.
Thank you very much for your hard work. Toast!
