. When first opened, the bridge was crossed by just over 1,000 vehicles per day, on average. Tolls were removed from the bridge in 1976, and by 1978 the average daily traffic had risen to over 2,500 vehicles per day. By 2006, traffic counts reached 11,309 vehicles per day but shrank to 6,900 Annual Average Daily Traffic in 2017.

History

Originally initiated on November 16, 1938 by the creation of the Lower Rappahannock Bridge Commission, planning work on the bridge began in earnest in 1950, and construction began in 1954. Four workers were killed in construction accidents on the bridge.

Present Day

Between the opening of the bridge and the placement of the current traffic safety barrier, there have been two known fatal accidents involving cars crashing off the bridge into the water below. Prior to July 2021,

operated a 115 kilovolt (kV) transmission line that was attached to the East side of the bridge. This bridge-mounted 115 kV transmission line was removed after a replacement underwater 115 kV transmission line was brought online. This transmission line replacement was identified by Dominion Power as a needed project in order to remove risk of violating mandated NERC standards. Increased inspection routines relating to the age of the bridge itself required the attached transmission line be de-energized each time the inspections were carried out. The Virginia State Corporation Commission (SCC) later ordered Dominion Power to route the new transmission line underwater.

Future

The Robert O. Norris Bridge has been identified as a State of Good Repair Infrastructure asset in that the pavement and superstructure of the bridge are deemed structurally deficient and replacement should be performed at or before the end of its 75 year design lifespan in 2032. In addition, the Norris Bridge has been identified as being 'Fracture-critical' and the failure of one span could cause the total collapse of the structure much like the collapse of
