If you look at google maps, you'll see where the highway was redirected. Most people wish they would have built a bridge instead of redirecting highway T.Just like everything the corps of engineers do. They made the problem even worse. If they would have left it alone as designed. It would have barely went over. But government then and today. Thats why. It caused more damage. And to this day it would have costed less than they spent that then made it worse. And to this day it shows.
