WATERSHED SIGNS

I have been pondering for a long time, about the function of the watershed signs on the interstate. They are located at every river, creek, or body of water the interstate crosses. I initially thought the signs were a colossal waste of taxpayers money. But after the floods in Nashville, and the Corps of Engineers diverting the water down the interstates, I finally saw the relevance. When global warming hits, and the glaciers melt, the Corps of Engineers will again direct the water down the interstates. The water will see the signs, and know where to go.
