How would we add do a relation network tag for Business Route U.S. 58 Alt. in Norton, VA? Would it be network=US:US:Alternate:Business?--Zhicks89 (talk) 01:18, 17 May 2014 (UTC)
First 2 digits are the FIPS code for VA (51)
Last 3 digits are the county FIPS codes.
Please try posting your question on the MappingDC mailing list. It's a google group. --OpenBrian (talk) 02:18, 31 May 2014 (UTC)
