If local laws permit, the 319 bridge over the river looks like a safer bet than the 153 due to its much wider shoulder. I didn't see any signs on the onramp prohibiting bikes on the highway, but check with the Department of Highways (or whatever its called in Tennessee) to be sure.
I suggest picking up front and rear lights ($25-30 should get you a basic set), and some sort of high visibility vest (like this or this). If you're riding after dark, some reflective tape on the bike would make you stand out in headlights.
Good luck, and stay safe.
