I have a few pictures of a new Fiberglass Reinforced Polymer Composite Bridge Deck. :shock:

The Bridge deck sections have lots camber ( upward arched curve in the middle ) and it looks like it will have a concrete road surface. It will be interesting to see how well this stands up over the years of use.
The bride is over salt water about two miles from our house.

It will be interesting, any weight limit going to be on the bridge? They are doing a lot with composites, it may well be a answer to a lot of bridge work in the future if it works out.

The bridge will have to support the weight of a full concrete mixer truck....so I think it would not be rated less than 80,000 lbs. The old bridge, made with wood, does not have a posted limit and the concrete trucks are on it every day.

MA ought to look into this. All our bridges look like a '74 Pinto that's been driven in winter since new. :lol:

Good idea, being so close to salt water.

If it is a road that receives any federal highway money it must be able to handle all vehicles.

This is the Nnickerbocker Bridge in Boothbay, Maine. Its an eight span 540-foot-long $6-million repalcement structure.

This web link has a video section on the fiberglass beam construction.

Well, if anyone was inclined to "burn their bridges", this would be a good candidate.

The environmentalists probably had a hand in the bridge design. They don't like paint and paint removal techniques. Gotta think about those lobsters. They have a fondness for paint chips.

I would guess that its a maintenance thing, If everything holds up they have taken away most of the costs of doing all that sandblasting & painting every so often to still have it rust away. If it holds up well this will most likely be the bridge material of the future, even if it doesn`t have quite as long of a life span it would still come out cheaper in the long run, all benefits to the environment is a bonus.
