Perhaps they work for you. In this town the question from most motorists
is "Why?" So far any rotaries have been constructed at intersections
where there is seldom any traffic. What passes for heavy traffic is all
on light controlled routes. The only thing that would help the major
problem street would be a bypass. That's what happens when the big box
stores all congregate on what used to be a two lane road on the edge of
town.

We did have one six way intersection that might have benefited from a
rotary but the final solution was blocking some of the legs and creating
a confusing set of detours to get around it. It drastically reduced the
wait times but that might just be because many of the businesses in the
area didn't survive the renovation.
