I am in favor of roundabouts. They save on gas used while waiting at stop lights, they slow down the traffic so if there is an accident, it is at a lower speed, and most of all, they keep traffic flowing. Your report on the proposed roundabout at the entrance to the Phippen Museum, however, indicated that the planners were concerned only with the impact on the immediate area. My husband attended the meeting, and the planners were not taking suggestions at that time. Apparently they were there just to inform.
The current plan is to widen the road north of the roundabout to four lanes, narrowing down to two lanes south of the roundabout. The entrance to the Granite Gate Senior Living Center, and the housing development behind it, is more than a mile south of the Phippen, right at the two lane bottleneck. From this entrance, it is difficult to turn onto Highway 89 at present, with long waits for a gap in the traffic. It is likely to be adversely affected by this roundabout because the traffic will be more evenly spaced out with the roundabout, with plenty of time to speed up again to 50 mph.
I suggest that a traffic light be installed at this intersection, triggered only by a car at the stop light. Highway 89 will eventually need to widened to four lanes all the way, but as an interim measure, this could prevent accidents and save lives.
