Platte River Bridges
The most expensive, and some of the most extensive, flooding in American history affected several Midwest states in the summer of 1993. During this disastrous event, the Platte River (MO version) crested just above the bottom of highway and railroad bridges. At the time, the highway bridge was still open (!); but the railroad had long been closed and criscrossed by sandbag berms (unseen). The water was carrying large debris (including trees and furniture) at times, which would bounce off the upstream side of each bridge before being pulled underneath and emerging downstream. Vibrations from the flood current and embedded debris could be felt in a moving car on the highway bridge. It should have been closed.
