I guess that should be all hands on abutment not deck. Saturday morning and all three bridge building helpers were there anchoring the treated 2 x 12's that will act as a barrier between the concrete abutments and the bottom chords of the bridge trusses. This separation (I can never spell this word but my wife the teacher says there is "a rat" in the middle) will minimize moisture wicking up from the concrete and rotting away the untreated chord material.
Puzzler - How many gallons of finish will to take for the bridge project?
