I think having a traffic circle in the form of a roundabout would not be so safe on California state route 41, Atascadero Road at Main Street. I’d rather see a traffic signal placed in that intersection. It is too dangerous for pedestrian traffic to cross over, just like the roundabout at Quintana Road and Morro Bay Boulevard off of California State route 1, the Cabrillo Highway.
It kind of reminds me of the time that cloverleaf interchanges are no longer popular in the United States, and in California too, on freeways such as the removed cloverleaf interchange at the Santa Ana Freeway and the Costa Mesa Freeway, (Interstate 5, old U.S. 101 and California state route 55). I prefer the four level interchange for freeway-to-freeway interchange such as the inverted four level interchange on the San Bernardino Freeway, Interstate 10 (old U.S. 70 and 99) and the Ontario Freeway, Interstate 15.
In closing I avoid the roundabout if necessary when I am doing my errands on a weekly basis in Morro Bay. I don’t think that they are popular to most Americans.
