6x29 Piston Bridge

Here's a new version of my piston bridge. It's 6 wide and 29 long(although you could shorten it by removing some of the segments.) Each segment raises a 1x3 block of pistons. The main objective when I made it was to cross some water in a castle i had, so have included water. the water fills in the gap left by the pistons pulling the sandstone bridge down.There is a push button on each end to toggle the bridge, thanks to a piston flip-flop on each side of the bridge. all the air has been removed from the inside of the circuitry, using cobwebs to fill in where there needed to be air.
