Wood on Concrete Bridge Deck
Wood on Concrete Bridge Deck
(OP)
Have a residential bridge where wood timbers are to be the finish flooring/decking. The structure of the deck is steel beams supporting a concrete on metal deck. As far as the wood timbers are there any recommendations for longevity of the timbers. Probably want to put spacers (composite material) between concrete and timbers to prevent rain water from collecting at base of timbers. Any other recommendations?

I would put the wood in the traveled way, as they are a wear strip and expendable. I would also place them parallel to the direction of travel, encouraging people to drive there and not elsewhere on the span.

Putting the wood on top of the concrete just makes it sacrificial. Even the splash from rain is eventually going to get the wood, spacer or no.
If you're just using the wood as a cushiony deck, that mission might be better served by that saggy recycled plastic pseudo- lumber decking stuff.
