While many of our roads nationwide are rough, the scariest I was ever on was in Southern Missouri...I cannot recall exactly where as we were off the beaten path just seeing the country after spending time in Branson. We went through a smallish town and had to cross a river on a bridge that was fairly high above the water. It was so narrow that I'm glad I did not meet a large truck or another motorhome coming from the opposite direction. The bridge was in such bad condition, that parts of the safety railing were gone or hanging over the side and there were literally holes through the entire deck thickness such that we could see completely through them to the water far below. Those were basically right at the edge of the bridge, but with it being so narrow, I had to hug the centerline to keep away from them and it certainly made me wonder exactly what I was driving on.
How something like that stays open to traffic is beyond me.
My understanding is that just grinding away an old blacktop surface and resurfacing a two-lane with shoulders costs approximately $1M per mile. At least that's what our county people tell us. At that rate, I can see how the many millions of federal funding can seem like a lot of money spent, but taking into consideration the milage of bad roads to be covered across the US those funds are but a drop in the bucket of what is needed to get our infrastructure back into the shape it should be.
