Witch in the wardrobe

Locked in - never read the books.
Busy garden day digging rubble tamping and shifting gravel.
A little rain mid morning so took to the kitchen with a coffee and sketched out details for the replacement bridge which is only 1 metre wide and 3 ( 10 ft ) long, and crosses the burn.
Will use reinforcing bars in the holes of dark blue engineering bricks with some concrete cover.
Must remember to include ducts for water and electric and bases for handrail balusters etc.
