Editing Interstate 40 (section)

===Geological difficulties===
Landslides are common in the Pigeon River Gorge section along the Tennessee and North Carolina border. Here, the roadway was cut into the slopes of several steep mountains. Accidents on the winding road are also common especially during bad weather. On October&nbsp;25, 2009, I-40 was closed at the North Carolina and Tennessee border due to a landslide at milemarker&nbsp;2.6 just east of the Tennessee state line. All traffic was detoured via I-26 and I-81, and non-heavy-load traffic via US&nbsp;25 and US&nbsp;70.<ref>{{cite news |first = Stephen |last = October 27, 2009 McLamb |url = http://www.volunteertv.com/news/headlines/66605652.html |title = HWY 25-70 a scenic, tough rock slide detour |publisher = [[WVLT-TV]] |access-date = November 27, 2011 |url-status = usurped |archive-url = https://web.archive.org/web/20100215020545/http://www.volunteertv.com/news/headlines/66605652.html |archive-date = February 15, 2010 }}</ref> The roadway was reopened on April&nbsp;25, 2010, with some remaining limitations on westbound traffic.<ref>{{cite news |url = http://www.knoxnews.com/news/2010/apr/25/section-of-i-40-back-open-after-oct-slide/ |title = Section of I-40 closed since Oct. rockslide reopens |last = Hickman |first = Hayes |work = Knoxville News Sentinel |date = April 26, 2010 |access-date = April 26, 2010 }}</ref>
