Moving Blocks

We found these cement blocks by the side of the road for free.  Ryan decided they would be great to use as a retaining wall behind the garage.  How to get them back there?

Build a bridge....

The end result, 8 buried blocks replacing a rotten railroad tie as a 8 inch high retaining wall.  40 more square feet of garden space.  The last 5 bricks to be installed after next compost pile turning.
