Total waste of time doing this only to get it. Washed away should first build retaining wall plus water pipes to allow water to flow under.Some culvert pipes should benefit placed there!This is a perfect example of how being cheap ends up costing more money.Entertaining though and wonderful machines.These are projects in Asia designed mostly to create debt. They invest in road building to create more debt, the banks usually own the construction companies who make huge profits and then sell oil and gasoline to those who drive on these roads. IMF loans are written full of kickback projects like this as a part of their loan contracts, using contractors who are owned by the banks. This is why there is so much flooding in China. Lots of videos showing dump trucks dumping dirt into wetlands, or building roads through natural wetlands. This will act as a dam and will absorb water and actually sink and wash out and the work and fuel wasted but the debt will remain.
