Virginia Department of Transportation finished installing weight monitoring near the Robert O. Norris Bridge, wrapping up a week of overnight lane closures.
The weight sensor equipment is located on the Lancaster side about half-mile north of the bridge’s approach. Vehicles don’t have to stop to be weighed. The equipment is embedded in the pavement and designed to gather information from vehicles traveling at speed, similar to the equipment used for traffic counts.
The bridge has a posted limit of 45 tons.
When asked what triggered the need for this equipment and if the department has concerns that the weight limit is being exceeded, VDOT responded saying, “The Norris Bridge is safe for travel. As part of routine maintenance activities, VDOT structure and bridge engineers wanted to track the relationship between overweight vehicles crossing the bridge and any additional stress being placed on the structure. The weight monitoring equipment is being installed so engineers will have more information about the frequency and loading of vehicles that may be crossing the bridge.”
