Yes. In Europe, they build roundabouts so that a dimensional load can drive right through them. We'd like to see that in future designs, because right now we don't. The dimensional load is a concern whenever there is a roundabout. Some of them aren't large enough to handle those loads. I know municipalities all configure the same dimensions when they build roundabouts, but it probably should be revised to handle those dimensional loads.
