I'd forgotten about the plans for a roundabout at that location. I knew, at one time, they were looking into trying to work one out in the Seven Points area and I kept thinking that would be one total cluster-flop (yeah I do know that's suppose to be another word). I know there are some places where a roundabout improves things but, in a town like Florence, it's just liable to confuse more people. The place that I have found a roundabout did the most improvement was right before the Bachman Tubes (one of the Tunnels) in Chattanooga, TN. Chattanooga put a roundabout on the Chattanooga side of the Tunnel's entrance/exit where there were two roads leading to the tunnels and it actually greatly improved a place where traffic was always jammed up and very dangerous to navigate.
When people know how to navigate a roundabout they help traffic flow but throw one driver that is very timid and scared in the mix and it can make it real interesting.
