Rev, I know that I-65 crosses over the Tennessee River in Decatur, Alabama. This is part of the Wheeler Wildlife Refuge. I'm not sure if it crosses over in another area also. Me and a friend launched a boat there about two years ago, I dont remember the exact location, but I think there are several areas to launch there. We caught some good crappie during the winter months next to the big bridge pilings. They were holding behind them in the water break. We caught them on 1/16 oz tube jigs. Good Luck
