In addition to the 30-A traffic, the 395 traffic, and the bicycle traffic, it looks, to me, like there will be traffic coming out of, at least, two or three driveways entering the circle. Let's hope these homeowners aren't backing out...
Sure would love to see a sketch of how the engineering firm thinks this will work. Sounds like quite a challenge.
According to this graphic, all the negative and really negative attitudes pre-traffic circle are going to be positive after construction.

According to the graphic, there is not a single negative opinion post construction. That is just not realistic.
