Editing Interstate 3 (section)

==Route description==
The actual route of I-3 is unknown. However, the 2005 SAFETEA-LU legislation indicated that, in Georgia, I-3 would follow the existing Savannah River Parkway from Savannah to Augusta.

Due to the difficulties of building a new highway through the [[Appalachian Mountains]], the highway's proposed route north of Augusta is less clear.<ref>{{cite web|url=https://www.fhwa.dot.gov/planning/section_1927/3rd_infantry_highway/design_levels/dl09.cfm|title=U.S. DOT - Study Alignments and Design Levels Draft Technical Memorandum: Appendix A: Preliminary Corridors|publisher=|access-date=October 4, 2014}}</ref> In early 2008, officials introduced the possibility of routing I-3 through [[Greenwood, South Carolina]], and continuing on to [[Greenville, South Carolina|Greenville]].<ref>{{cite news |url=http://onlineathens.com/stories/010208/news_20080102045.shtml#.VeOgKPlVhV4 |archive-url=https://web.archive.org/web/20080105071705/http://onlineathens.com/stories/010208/news_20080102045.shtml#.VeOgKPlVhV4 |url-status=dead |archive-date=January 5, 2008 |title=Opponents of interstate hope for alternate route |access-date=May 13, 2018 |publisher=OnlineAthens.com |df=mdy-all }}</ref> Other potential routes continue in Georgia along [[U.S. Route 441 in Georgia|US&nbsp;441]], [[U.S. Route 129 in Georgia|US&nbsp;129]] (along [[Deals Gap, North Carolina|the Dragon]], an {{convert|11|mi|km|adj=mid|-long}} stretch of road in North Carolina and Tennessee adjoining [[Great Smoky Mountains National Park]] with 318&nbsp;curves), or [[Georgia State Route 77|SR&nbsp;77]].<ref name=fhwa/>

The proposed numbering of the highway does not fit within the usual conventions of the [[Interstate Highway System#Numbering system|existing Interstate Highway grid]], where primary north–south highways are assigned odd numbers, and such odd route numbers increase from west to east. Under the normal Interstate Highway grid, I-3 should instead be located on the [[West Coast of the United States|West Coast]] between the [[Pacific Ocean]] and [[Interstate 5|I-5]]. All odd numbers between [[Interstate 75|I-75]] and [[Interstate 95|I-95]] are already assigned, but most of them are confined to states well north of the proposed route. The 2017 approval of the second [[Interstate 87 (North Carolina)|I-87 in North Carolina]] in addition to the [[Interstate 87 (New York)|I-87 in New York]] may indicate willingness to duplicate other north–south route numbers.<ref>{{cite web |url = https://outerbanksvoice.com/2016/05/26/future-interstate-from-chesapeake-to-raleigh-will-be-i-87/ |title = Future interstate from Chesapeake to Raleigh will be I-87 |last1 = Walker |first1 = Sam |date = May 26, 2016 |work = The Outer Banks Voice |access-date = August 14, 2017 }}</ref>
