奥只見シルバーライン

A time tunnel that extends from space and time to the Showa era from the modern world. As the orange sodium lamp travels through the endless tunnels and reaches the exit, the view is wrapped in a white fence .... A road originally made for dam construction because there is no road when constructing the Okutami dam. After the dam was completed, it was transferred from the power supply development to Niigata Prefecture, turned into a sightseeing toll road, and then opened for free in 1977. As for the way around here, along with Route 352, it is a very dark road, and most of the silver lines are tunnels, Route No. 352 can be cut along the ridge of the mountain and how many times you cut the handle! There is also a crying, and if you are interested, I would like to go ahead on each road. By the way, it would be nice to let the Silver Line run nicely as the Kanden tunnel of Kurobe Dam, which was also built for dam construction, can not run a general car. In addition, I do not know whether this is true, but there is a place where a straight line of sodium lamps deviates with one point, and it is because the tunnel was dug from both sides and the penetrating part deviated, but the real What is the place? Whether you notice the place anyway depends on your own attention. What on earth do you say with the time tunnel etc? It might have been thought that it is a joke that it goes beyond space and time, but it is not that all of you tend to lie, but the taste of soft cream of mountain grapes that are sold there or souvenir shop in Okudadami Dam The atmosphere is very Showa-like because there is nothing now. Well, if you go here during the hot summer months, the car body cools down in the tunnel, and when it goes out the windows called windows will condense and become white and block the view. (Very good!)

Although it is a dead-end tourist destination, it is a long hand-carved tunnel that connects to Okutadami Lake and was made for the construction of a dam, and has been selected as one of the 100 best roads in Japan. It is currently open for free, but motorcycles are impassable. Also, the long hand-carved tunnel that continues to the end is like an entrance to another world, and it may look like an Instagram, but it is dangerous, so please do not stop the car or take a picture on the road. .. In addition, the width is narrow and the windshield becomes cloudy due to the temperature difference, so not only beginners but also sightseeing buses run, so be careful when driving!

Passed in early September 2019. The Okutadami Silver Line is a long tunnel that extends 18.1 km out of a total length of 22.6 km, which is the section of Kamata Orizada to Okutadami Dam. There are some places in the tunnel where there is no clear see through.

The tunnel side wall is a very tasty road as it is from the rock mass The road surface seems to be wet all year. Be careful of cloudy windows in summer, around 30 degrees outside and around 15 degrees inside the tunnel Cloudy outside and inside, depending on the situation In winter, general vehicles are closed. Reiwa 2 was canceled on March 7 You can see Echigo Komagatake large near the first tunnel "Third Tunnel Group" on the Silver Line

It's close and free! It is very convenient from Uonuma to Okutadami, Ginzandaira, and Aizu. It is a nice tunnel with a feeling of digging.

It is Niigata Prefectural Road No. 50, which is the access road to Okutadami Maruyama Ski Resort and Okutadami Dam. Pedestrians and motorcycles are not allowed. Originally created by Electric Power Development Co., Ltd. for the construction of Okutadami Dam, 18km of the total length of 22km is a rare road called a tunnel. There are still uncut walls, and there are T-junctions with traffic lights (although it is a one-lamp type) even though it is a tunnel. At the time of my visit, in early April, National Route 252, which connects to the T-junction, was closed due to winter closure.

A tunnel with an open pit section and a feeling of unexplored area where groundwater seeps out. The total length of the tunnels is about 18km and there are signals. It's a fun tunnel to run.
