	Be careful. The conex are not strong in compression like that - they are designed to have the load on their frame where the lifting hooks are. Loading them in between (like driving over one) they are not very stout. Kinda like a beer can, you can stand on one, but tap the skin with your finger when its loaded and it will collapse.

	Doc is right. Unless its foor traffic or atv traffic, I would do something else. Not sure they would hold up to a jeep on top of them for long term without extra reinforcement. The doors being closed are also part of the structure for them. I've also never seen a cheap one as folks tend to patch them. I've literally been looking for one or two for years at this point.

	I have seen some nice culverts/bridges made using those connex boxes. There is a very nice one on the road from Grays Chapel to our cabin. The problem is that usually they also place a reinforced concrete slab on top of the connex box to carry the heavy loads. There is no way to get a concrete truck back to where this thing would be going. The other thing they do is flip them upside-down and use the floor as the roof since the connex floor is stronger. Also, it will have to support some heavy loads; like a triple axle dump truck and a 75,000 lb excavator. I think they originally priced a 20' section of 6' corrugated steel storm drain pipe and thought the connex box would flow more water and 50% cheaper. After adding in a reinforced concrete slab to the cost of the connex box, there is no savings there. Their design seems to have evolved back to using a 20' piece of 6' storm pipe. Larger diameter of pipe require more dirt/crushed stone on top of it to distribute the load and prevent crushing the pipe, generally 1' for small pipe carrying normal loads and at least 1/3 the pipe diameter for larger pipe. I would want to use more cover than that since it will have to carry heavy loads and the roads deteriorate pretty quickly up there. I suggested using two 36" or two 48" pipes instead of the 72". Several land owners are paying for this, so its "design by committee". Edited by 98TJ - 06 February 2025 at 12:53pm

	Using two 36 in or 48 in culverts seems like a much better idea. It's easier to deal with 3 or 4 ft culverts bs the 6 ft. Takes long straps to go around them. The connex are 8 ft wide so that's a lot of span for that much weight. Edited by 83K10 - 07 February 2025 at 7:30pm

	Here is that storage container bridge near Grays Chapel. It has a thick reinforced concrete slab on top of it.
