I've read the Tohoku Expressway is damaged. This is the main expressway from Tokyo via Sendai towards Aomori in the north.

I like Japanese expressways. I only don't like two things:
1st, they drive on the left. As I said once in the British road thread, driving on left means dictatorship, while driving on the right means democracy (At least for me...)
And 2nd, THEY DIDN'T NUMBERED THEIR EXPRESSWAYS. Is better to remember a number than a name!!!
There I was thinking driving on the right was a Napoleonic-Bolshevist imposition ;-)

Seriously though I was very surprised by the low speed limit on Japanese expressways (80 km/h from memory). It took about 9 hours to get from Osaka to Tokyo by coach.

Flooding from the tsunami can still be a problem, but other than that, the bulk of infrastructure fared great for an earthquake of this magnitude as far as I can tell from the news and videos.

Sendai Airport was directly hit by the wave.

The main expressways in northern Honshu are further inland and are unlikely to be affected by the tsunamis. Their main concern are local roads along the coast which are inundated or completely washed away. The largest city in the area is Sendai, which lies in the coastal flats, but is not located directly along the coastline but a few kilometers inland. Sendai Airport is closer to the sea than the city itself. The outskirts are likely to be destroyed, including the Sendai - Tobu Toll Road (a 2x2 expressway).

The problem is that even when the rail and highway viaducts may look fine to the regular eye, there might be hidden cracks, for example, which may decrease their integrity. I suspect that at least some viaducts will be closed after further inspection.

They run a full check of the entire Shuto system in Tokyo within 3 hours after an earthquake. If there are no irregularities detected, traffic can flow again. They're very efficient with this in Japan.

My guess: that road consists of concrete plates, two plates wide. The plate holds the earth below it together, but isn't connected to the plate of the other lane. The border runs along the center of the road of course, giving this odd running crack.

As I've seen from live footage, this is actually a small landslide. Probably upper part of the road was built much before the second part, so the substructure of the road was different for the left and right side so sides behaved differently. There are no concrete plates visible in cracked road.

The major highways, expressways around Tokyo are OK or damaged?

Tokyo was too far away from the epicenter to have received significant damage on the Shuto system.

It's amazing that the asphalt didn't buckle on the lane on the left side of the photo. That's pretty strong pavement if you ask me!

Actually ground slided away from the middle of the road. Upward there was almost no deformation of the ground hence (almost) no deformation of the asphalt - this can be seen at the stone curbs.

That road in the above picture is the main road to Sendai airport?

Two Expressway openings in the past few days. (no tsunami is going to stop the Japanese road-builders )

* 19 March: Kita-Kanto Expressway: north of Tokyo. Last missing link completed
* 20 March: Mei-Nikan Expressway: Nagoya ring road. Southeastern link completed, mostly undergrond (formerly Higashi-Meihan Expressway).

A major project that could be affected by the tsunami and nuclear power plant troubles is the Joban Expressway between Yonomori and Sendai. This road runs through the affected area (though probably high enough to be safe from the tsunami) It's only a few kilometers from the Fukushima I & II power plants (though these power plants are actually over 60 kms away from the city of Fukushima). This expressway link was supposed to be completed in 2011.
