I-79 begins at a modified [[full Y interchange]] with [[Interstate 77|I-77]] along the northwest bank of the [[Elk River (West Virginia)|Elk River]] just northeast of [[Charleston, West Virginia|Charleston]]. (Instead of the expected treatment of I-77 as the primary route at this interchange, the following traffic movements are found: northbound I-77 through traffic curves to the left, while traffic to northbound I-79 exits right; southbound I-77 through traffic curves to the right and merges on the right with traffic from southbound I-79, while traffic to northbound I-79 both exits and merges on the left; southbound I-79 traffic merges on the left with traffic from southbound I-77, while traffic to northbound I-77 both exits and merges on the left.) For its first {{convert|67|mi|km}} to a point just south of [[Flatwoods, West Virginia|Flatwoods]], I-79 is located in the [[drainage basin|watershed]] of the Elk River, which drains into the [[Kanawha River]]. It crosses the Elk River at [[Frametown, West Virginia|Frametown]] and again at [[Sutton, West Virginia|Sutton]] and never strays more than about {{convert|15|to|20|mi|km}} from it.<ref name=topos/><ref name=watersheds>[[National Atlas of the United States]], [http://nationalatlas.gov/atlasftp.html#hucs00m Hydrologic Units (Watersheds) GIS data]{{webarchive|url=https://web.archive.org/web/20130504145622/http://www.nationalatlas.gov/atlasftp.html|date=May 4, 2013}}</ref>
