SR 185 is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. History In 1996, the city of Oakland renamed its portion of East 14th Street as International Boulevard to acknowledge the cultural diversity of the route, and to address the stigma of the segment being seen as a high-crime area. In 2012, the California legislature relinquished control of SR 185 in Downtown Hayward between SR 92/SR 238 and A Street to local control. In March 2013, this segment became part of a one way circulation known as the "Hayward Loop", designed to improve traffic flow between SR 92, SR 185 and SR 238.
