Japanese Engineering???

I saw this today:

 I couldn't figure out how to post the picture.  If that is true it is an amazing feet of engineering and productivity.  I am highly skeptical however.  That is just way too much to get done in 6 days on top of the massive amount of other work that is being done in Japan.  If anybody could do it they could though.  I wonder how long it would take a caltrans crew to pull that off.
