What I want to know is how are they doing this for a road? They must be using some amazing blowers.

Wow awesome

I guess this is the highest number of lanes in Japan (in one direction)?

It possibly is. Quite some cities have streets with four lanes in each direction (2x4), but this is the first I've seen with eight lanes in one direction.

Midōsuji is by far the most important street in Osaka--just like Market Street in San Francisco or Fifth Avenue in New York City. And just like Market Street, there are extensive underground public transit--in this case, the Midōsuji Line subway, the most important subway line in Osaka.

I looked at some of those photos and they had a queue of cars trying to enter the service area stretching all the way to the hard shoulder of the mainline. And that was despite advanced warning that the parking is full (seen on other photos).

What was that about? Were people just curious and tried to test the services after opening?

The road looks impressive but must be nightmare to maintain with all those tunnels as well as deep cuts to the mountainsides.

That warped grid retaining wall thingie on the left-- it looks like something from a Dali painting. In fact, the whole scene looks a bit surreal to me.

Hanshin Expressway - Route 5 Bayshore Line

14.5 km from the Route 5 Bayshore Line in Kobe will begin its construction in 2016. Expressway will continue from Rokko Island (north) to Komae.

Total cost of the project will be around 500 billion yen.



The coastal Expressway starts in the bridge to the Kansai Airport and follow the harbour line along the Osaka Bay. In the future will end at the junction with the Kobe-Awaji-Naruto Expressway. 80 km in total.

This big project will include two bridges connecting the Rokko Island and Port Island, and another connecting Port Island and Wakadamisaki ward.

Project in detail:

Japanese Police is considering to elevate the speed limit on expressways to 120km/h

Quote:
NPA to test higher speed limit on expwys



TOKYO (Jiji Press) — The National Police Agency has decided to test a higher speed limit on some sections of the Shin-Tomei Expressway and the Tohoku Expressway, NPA officials said Thursday.

The speed limit will be raised to 110 kph from the current 100 kph on a section of the Shin-Tomei Expressway in Shizuoka Prefecture and a section of the Tohoku Expressway in Iwate Prefecture.

The expressway speed limit has never exceeded 100 kph since the Meishin Expressway, the first one in the country, opened in 1963.

Local public safety authorities will set further details of the tests. The agency will examine the test results to consider whether to eventually raise the speed limit up to 120 kph.

Most of the Shin-Tomei Expressway is straight, and its design allows cars to travel at 120 kph without a problem. Many people drive their cars at speeds over the current limit on that road.



Bridging the gap between the current limit and the speed at which many people actually drive would be appreciated by the public and, at the same time, help raise the effectiveness of the speed limit, an NPA official said.

The speed limit will be raised on part of the section between Gotemba and Hamamatsu-Inasa junctions of the Shin-Tomei Expressway and the section between Hanamaki-Minami and Morioka-Minami interchanges of the Tohoku Expressway. The Iwate and Shizuoka prefectural public safety commissions are to decide specific sections to be covered by the new speed limit and when to conduct the trials.

An expert panel led by then National Public Safety Commission Chairman Keiji Furuya suggested in December 2013 that the NPA should consider an increase in the speed limit to over 100 kph on expressways that have three lanes each way and are designed to allow 120-kph driving.

Finally a speed limit increase for major roadways.

100 km/h is bloody slow which causes more accidents because of an unrealistically low speed limit.

120 km/h is better (with at least +10% tolerance )

I do have one big concern though: can those non-turbo version Kei cars be able to accelerate safely to 120 km/h, let alone cruise at that speed? Could be a bit unsafe to drive a non-turbo Kei car on the Tomei Expressway in the future, in my opinion.

Hmm.....they can stay in the slow lane(s) (a.k.a. the lanes closest to the shoulder) and leave the more powerful cars with more than 100 HP to use the fast lane (e.g. the lane closest to the central median/divider).

Opened at traffic the westbound undersea tunnel of the National Route 357 (runs parallel to the Bayshore Route )



The NR357 connects Chūō-ku, Chiba with Yokosuka in Kanagawa with a total length of 70 km.

A public act was held last weekend:

A few years back I viewed a 3D video that depicted the path of the Yamate Tunnel—either section C2 or C3—and the complex technological challenges building it. The video illustrated how the tunnel wove around subway tubes, and in one instance, actually went between two subway lines.

Is this video still available? I've searched, but haven't come across it. Can someone post it again or provide a link? Many thanks.

This new tunnel that just opened along the Bayshore, its like a local tunnel alongside an expressway, right?

I would expect them to be able to. The maximum power of Kei cars has been increased in 1990, so the number of old models still in use would be low. Many Kei models are being exported in large numbers to countries where 120 km/h or higher has been the norm for decades now. In any event, if certain cars cannot safely accelerate to / cruise at 120 km/h, their drivers should drive slower than the maximum speed. There is nothing unsafe at that. There is probably some upper limit to speed differences on a stretch of road (say, people driving at 50 and 150), but you won't hit any critical level by allowing speeds of 120 km/h if some cars remain stuck at 100.

When I drove through Central Honshu last year, I was not inasmuch stunned by the 100 km/h national speed limit, but by the long stretches of (non-urban) motorways where variable speed limits were set at 80 km/h for no apparent reason. Motorists also consistently ignored those 80 km/h limits. But as much as it's nice that they are now considering an increase to the NSL, you wouldn't make much progress unless they also start turning off those unnecessary variable speed limits.

The top speed of K-cars is around 130-140 km/h. 120 km/h may not be suitable as a cruising speed for long drives as the engine would be revving to high, but a 120 km/h speed limit does not mean everyone has to drive that fast. Driving 100 in a 120 is also safe.
