You mean the fences? These are quite common in Japan, even along expressways.

Want to see how a tsunami looks like from a car? Here you can see it (I can't add it directly like youtube videos).

i mean during asphalt and concrete layering, there should be some sort of steel reinforce at grade for structurally wise. usually we put steel deformed bars.

I think this is not just some prefectural road, but the Joban Expressway. No wonder they repaired it so fast. I think I found the location on Google Earth, but the Street View is crappy.

I'm surprised there was this kind of damage so far south. Mito is well over 200 kilometers south of Sendai, almost on the outskirts of Tokyo.

It looks like a land slide. Sometimes small shocks are enough to trigger them in prone areas.

it is for taking out the snow easily though Joban Expressway does not have much snow

Does anyone know what these structures over the road are for? This was in Hokkaido in the north of Japan, on the road from Akanko to Kushiro. I guessed they were something to do with snow because there wasn't anything similar in the south.

Judging by the positions of the arrows (points to the edge of the road) then they are most likely for snow clearing. And since that image is taken on Hokkaido you never know how much snow they get at that point. I have seen images where roads are cut into the snow, leaving several meter high snow walls on the side of the road.

Maybe it's to denote an edge line when snow covers the surface?

I finally got around to calculating the length of the Japanese expressway network. Most internet sources - including Wikipedia - give numbers of around 8 500 kilometers, but those figures are usually from 2005 or older.

The 2011 number I calculated is 10 256 kilometers of expressways. This likely propels Japan into the top 6 longest expressway networks in the world. The list is as follows:

* USA: 95 589 km
* China: 74 000 km*
* Spain: 14 689 km
* France: 13 305 km
* Germany: 12 912 km
* Japan: 10 256 km

* Chinese figure is likely outdated due to the rapid development there.

The Japanese figure is impressive because of the density of the network, Japan is not as geographically distributed like Spain, France or Germany. Only 2 individual expressways exceeds 500 kilometers in length and there are only 17 routes longer than 200 kilometers.

There are approximately 900 kilometers of expressway in the Tokyo metropolitan area and 670 kilometers in the Osaka metropolitan area. The Nagoya metropolitan area boasts around 470 kilometers of expressways.

Two graphs made by me.

First: network length development. The Japanese system is remarkable in a way that the length development is nearly linear. Western Europe and North America had many eras of low construction activity, but the Japanese construction was always at the same speed, and still going strong. Already 100 kilometers of new expressways have opened in 2011.



Second: The amount of kilometers opened each year. The number has declined somewhat in recent years, no doubt due to the completion of most long-distances routes, though several new long-distance corridors are under construction. Another boom is anticipated in 2012 - 2016 period.
