The Robert O. Norris bridge is a truss bridge that spans the Rappahannock River between Lancaster County and Middlesex County in Virginia. It serves as the crossing for State Route 3 over the river. It was opened on August 30, 1957, and replaced the old ferry service. It is also known by locals as the White Stone Bridge or Rappahannock River Bridge. The water is over 100 feet deep near the center of the bridge.
