>>We have updated our files based on your request. Here is the
>>response from our updating branch:
>>"This request has been completed, and there are no more named S1740
>>features (driveways) in Campbell, VA. Those particular features
>>either had the feature name removed, or the feature was deleted
>>from the database altogether."
>>This update will be reflected in our next release of the TIGER/Line
>>shapefiles at the end of summer.

>> After some communication with Campbell County officials

>> I know that you will look into this, I would appreciate an

>> of the issue, our data guys can come up with some way to change

>> data about every other year to correct known issues.
>> Thanks for your help.
>> From your description, it sounds like you are looking at
>> Census, TIGER
>>data. Census adds these names to driveways, using the same name as the
>>road they come off of. This is something Census does for their use.
>>Campbell County does NOT duplicate road names.
>>Virginia has a statewide road database in which localities provide data
>>updates. Campbell County participates in this process. Statewide
>>street data can be viewed and/or downloaded from:
