Nashville has done a decent job of adding bike lanes in some areas. I am lucky that the side of town I live on has a mix of bike lanes and greenways(paved paths) to ride from my house to work 18+ miles and only 4 miles are on roads. Some of the bike lanes don't connect to others but I figure it is a good start. Our biggest issue here and it is the same for cars, is the river snakes through the city so there are many bridges and they haven't all become bike friendly, or you have a ride way out of your way to just get directly across where you want to go.
