I wonder how many lives have been lost trying to cross the water as it crosses the road. The engineers who build the railroads are another story. We have seen culverts 100 to 200 feet wide to handle runoff. Here on the northern edge of the Gobi Desert the tracks run straight and true as far as the eye can see. Back to the topic of highways.
Trucks can be a big problem.
I don't think they can ever be overvolumed, though. We've seen trucks with 30-foot high loads. Thus, we give these trucks wide berth when we encounter them. Unfortunately, when the crews are finished with their repairs, they simply drive away without removing the stones from the road, which subsequent traffic gets to dodge. But there are bicycle lanes.
