wood on driveway bridge
The end of our driveway crosses a small stream to connect with the street. The bridge consists of 3 metal I-beams, firmly attached to the banks, across which are laid oak planks (4" x 10" x 12'). Some of the planks are beginning to chip and crack and I would like to replace them. A local sawmill estimated $4000 to replace the planks.
I was thinking that if I bolted together some pressure-treated lumber planks to the dimensions of each of the oak planks it would look better and would be a fraction of the price.
The question is strength. Would my idea support our cars as they cross the bridge?
Re: wood on driveway bridge
Your best bet would be to check with an engineer as to the strength you need to support the heaviest load that will be crossing that bridge. If you just went ahead and did it without an engineer and probably a permit I doubt your home owners insurance would cover any damages if yours or someone else's vehicle went through.
