$200 DIY Heavy Duty Bridge

oh what's that you like my bridge well you two can build a bridge for about $300 what 400 okay maybe $400 [Applause] this one cost us about $200 because we already had a lot of the materials laying around but in this video I'm just gonna be showing you what we did to build this bridge it's like a 1 ton or two tons capable bridge we've tested it with two thousand one hundred pound tractor going across it and doesn't even move so it's pretty sturdy pretty heavy-duty and we built this one for two hundred dollars and I'm just going to be showing you the bridge and showing you how we made it so maybe you can get entertained by watching this or get an idea of how to build your own bridge if you have a place that you want to cross so the first thing we did was set the footings and we did two on each end of the bridge this is a 16 foot long bridge it's 8 foot wide we had 2 on each end and two in the middle and we use 4x4 posts for this and what we did was we dug down as basically as far as we could if we had long enough post but eventually we ran into rock because this is an old creek bed which is why we need the bridge but eventually we couldn't dig any farther and we called that good enough and so we set the post make sure they're level and use concrete to and dirt to fill the footings in and make them really solid after that we set some cross sections across each of the two sections of footing and that was used to really add some more rigidity to the footings into the whole bridge itself because like with a two by twelves the main beams stood on top of and it also add a little bit more of an anchor in case this Creek ever washes out a little bit more than it is right now [Music] the main structure of the bridge is comprised of two main beams each made up of two two by twelves and they're attached by carriage bolts to carriage bolts on each 4x4 posts to make them upright and make this bridge very sturdy all that was left after that was the top of the bridge and what we did was we used 22 two by sixes by eight foot long they're pre-cut to eight foot so we're not to mess with anything with that and then we just use 22 of them to space them out evenly across the top of this bridge and that's provided plenty of support because you want to space it out so that your main beams are carrying most of the load of any of the tires that you're driving across it and then this is mainly just if you get off line a little bit now when we attach these two by sixes we did notice that they they used to bend a little bit and so we did to counteract that once we had one inch deck boards that were 16 foot long just how long the whole bridges and we put that one inch deck board on top of each end of the two by fixes and then we were able to screw in the deck board on top of each individual two by six and what that did was it kind of attached all of the boards together so that they're each supporting one another and they can't bow quite as much as they used to so that added a bit of strength just like that and the other purpose that serves is in case it was ever I see we don't plan on ever using this bridge if it's bad conditions or anything like that but if you ever got offline or maybe it was I see a little bit you didn't know it these could act as a little bit of railings I guess a little bit of Stoppers so you don't go off the side of the bridge [Applause] how's it hip huggers [Applause] [Applause] [Applause] we also made sure that the whole thing was very level lesson right is a lot more important than you know if your bridge is inclining or declining obviously but we really made sure that the footings were level the 4x4 posts and the whole anchor in general was level and then that took care of the whole bridge when we did that to each side and made it really level and really sturdy so we could have done a lot of calculations to really figure out what this bridge could hold and how much materials we needed to build but around here we're more of just trial and error and so we just over built it from what we thought we needed and we knew that these main beams and this main structure here with footings at eight foot long will make this bridge plenty strong enough for what we're using it for and you could probably drive a truck across this because it just doesn't even move at all with that 2,000 contractors going across it so we think it's pretty safe but I do what I say and I want to point out that this is not for any of you guys to try at home because I will not be liable if you build a bridge and it breaks so don't do this it's very unsafe and for all I know this video might not even go up because I could be driving across it and it could break and I want to be able to finish this video so don't do this at home but anyway hopefully this gives you an idea of how to build a bridge if you need to get to the other side of a creek and just entertain you while you're watching it so anyway if you're new to the channel
