I my town they are doing some road construction around the main

large concrete blocks with a loop on the top to guy the telephone
poles. I'd estimate the block to be about 3 X 3 feet X 4 feet long.
Those are probably the same sort of 5000+ lb chunks we have at JPL.
It's probably a quasi standard thing. They're probably the right size
to stack on a flat bed truck trailer, etc.
And inexpensive to make.
You just need a crane or forklift to move 'em around. A flatbed truck
with a small crane would be the perfect thing to deliver and pick up.
The loop is ~3/4"-1" steel cable.
The telephone poles are used to hold up traffic signals that span the
intersection so there is quite a bit of weight up there and also a lot
of wind load.
