About this weird idea of "Smart IC".

The first Smart IC was opened on march 7th as Fuchu Smart IC (Chuo Expressway). This type of IC uses part of the bus stops in expressways and parking areas (PA).

Most new expressways are built as super-two highways, with only infrequent passing lanes, due to the low traffic volumes. The important routes have been finished since the 1990s, so they are currently constructing secondary expressways.

It is interesting to see how the network length development has been very linear since the 1960s. They opened approximately the same amount of new expressways every decade. In many developed countries the amount of new expressways / motorways declined significantly after the 1980s. Japanese expressway growth has tapered off only slightly since 2000.

The difference between official expressways built as a super two, and other super two highways is often minimal to non-existent. For example the Bantan Renkaku Toll Road from Himeji to Wadayama is as good or even better than national expressways.

Are they built with provision for expansion to full-size in the future? It seems hazardous not to. The Ken-O Expressway comes to mind.

They tend to run in mountainous areas, so widening it to four lanes would be quite expensive in any case.

Perhaps of interest, many bypasses in national routes were built with two lanes and then widened to four lanes, not rarely within 10 - 15 years of construction. That's either poor traffic forecasting or a strange way to fund road projects.

of course there are 4 lane expressways in Japan. Most of them were built before the 90s. These "Super-2" are new secondary expressways.

OK, I just asked because I've not seen any of them
I saw some roads in Google street view and none of them were 4 laned roads
And by the way is there any particular reason why the Japanese construct 2 laned roads instead of 4 laned????

well search better, Japan has actually more than 7000 km of (at least) 2x2 expressways. The best well known example is the Tomei Expressway.

And the reason why they're building these kind of expressways is simple, the amount of traffic is enough to build an expressway but not big enough to build a 2x2 typical expressway.

There are not many six-lane expressways in Japan, most are within the large urban areas.

On the other hand they often have multiple expressways between the same cities. For example there are two expressways between Tokyo and Nagoya (Tomei & Chuo) and a third is under construction (Shin Tomei). There are also two expressways between Tokyo and Sendai (Tohoku & Joban).

I'm confused as to how the Shin Tomei is supposed to be routed from Numazu to Tokyo. Is there anywhere to go to find the exact alignment?

The Namuzu to Tokyo section is a mix of a new alignment, widening and new carriageways.

A large section of the Shin-Tomei Expressway between Gotemba and Oi included the construction of one new carriageway with three lanes for Tokyo-bound traffic, and a conversion of the old 2x2 Tomei Expressway for Nagoya-bound traffic. (a cross-section of 3+2+2 lanes).

The Oi - Isehara section has six lanes, no construction is planned here as far as I know. They could eventually widen it to eight lanes (there are no long eight-lane sections in Japan yet). From Isehara to Ebina is a new alignment.

So it ends at the Ken-O expressway? Is that permanent or will there be another phase in the future?

The Koriyama JCT, where the Nishi-Meihan Expressway intersects the Keinawa Expressway.



By the way, I wonder if Japan has any cloverleafs. I don't recall seeing them.

Some parts of the expressway looks toll-free, others needs to pay. Don't know if it's because the works or what.

It's also one of the few expressways to carry a national highway number.

The third and final segment between Kisa IC and Sera IC was opened on March 22. 20,4 kilometers in total.

In general, new japanese expressways hasn't many signals comparing with the europeans, and those signals are very simple. Nice design.
