Concrete Truck

I've been meaning to post this and forgot - I finally got a half decent picture of one of these trucks the other day, while stopped at some lights. These tend to travel in packs of three or four at a time, led by a flag car. Look carefully and you can see the entire truck is split in two - the driveshaft is hanging loose underneath, at the rear.

I think the concrete section it is carrying gets used to make road flyovers. They have been building some around here recently and the concrete pieces all seem very similar. The ramp shown here immediately behind the truck is a classic example. There must be a factory south of here somewhere, it is not uncommon to see these trucks. It's just taken me a while to get a picture...
