A temporary roundabout could be showing up in the future at McHenry Avenue and River Road – which currently is controlled by a four-way stop. The San Joaquin County Public Works Department is scheduled to make a presentation later this month to outline the possibility of a temporary roundabout at McHenry Avenue and River Road to assist with traffic flow. According to county officials, this will be a temporary solution until construction of the new five-lane bridge and roadway improvements at the bridge over the Stanislaus River, spanning San Joaquin and Stanislaus counties.
