[QUOTE="MudHog, post: 1382068, member: 21686"] I'd have to look up the moment of inertia for pipe, but I have everything for beams and channels. A W6x15 beam 15ft would support 3000 lbs and deflect 0.423" in the middle which is under the max allowed of 0.500". A W4x13 beam would support 1000 lbs and deflect 0.362" in the middle which is under the max allowed of 0.500". W4x13 beam is about $6.10/ft or $122/20ft piece for an idea of price. All of the above is a single piece of beam and doesn't account for two pieces or center pieces to make an actual bridge. [/QUOTE]
