Thursday evening, Cal Trans will conduct a meeting regarding a proposed roundabout at the highway 46 / Vineyard drive intersection. Jim Shivers of Cal Trans says the meeting Thursday will allow the public to learn more about this project and ask questions of Cal Trans safety engineers. The formal presentation begins Thursday evening at six at Vineyard elementary school. The single lane round about would replace the four-way stop sign installed in July at 46 west and Vineyard. The intent was to stop the number of fatal accidents which occurred at that intersection.
