rebuilding an old bridge

We are looking to return an old bridge into service. It is a 28' long suspension bridge that goes over a marshy pond in WI. the water is only 1ft deep and when poking a stick into the marsh you appear to hit rock after about a foot down. there has been much discussion on how to add support to the bridge. One suggestion involves sinking to 8x8 posts and on either side of the bridge and then raising the bridge slightly and putting a cross beam under such as an "H" support. my concern is that with a rocky bottom we will not be able to sink the post sufficiently and that the pond will freeze solid and there would be potential to heave up in the spring and be detrimental to the bridge.

does anyone have any expertise or advise in this area??
thanks for your help

rebuilding an old bridge

First off, what sort of a budget are you looking at? and would you be able to consult an engineering firm for design? There are many different options, cheap and expensive, depending alot on weights and the strength of the soil base below and above water levels. Are you looking to maintain the old bridge as is? If so, new frame? Dismantle piece by piece, build new frame, with Pilings? And put the puzzle back together. Small driven pipe or H beam may be your best bet for strength and longevity. Timber is mainly used now as a great option for clay and saturted areas, and very low traffic support. Any questions, please ask. "Built a few bridges"
