'''Interstate&nbsp;70''' ('''I-70''') is a major east–west [[Interstate Highway]] in the United States that runs from [[Interstate 15|I-15]] near [[Cove Fort, Utah]], to [[Interstate 695 (Maryland)|I-695]] and [[Maryland Route&nbsp;570]] (MD&nbsp;570) in [[Woodlawn, Baltimore County, Maryland|Woodlawn]], just outside [[Baltimore]], [[Maryland]]. 

I-70 approximately traces the path of [[U.S. Route 40]] (US&nbsp;40; the old [[National Road]]) east of the [[Rocky Mountains]]. West of the Rocky Mountains, the route of I-70 was derived from multiple sources. The Interstate runs through or near many major U.S. cities, including [[Denver]], [[Topeka, Kansas|Topeka]], [[Kansas City, Missouri|Kansas City]], [[St. Louis]], [[Indianapolis]], [[Columbus, Ohio|Columbus]], [[Pittsburgh]],<!--Does not enter Allegheny County, PA, see [[Interstate 70 in Pennsylvania#Exit list]] --> and [[Baltimore]]. The sections of the Interstate in [[Missouri]] and [[Kansas]] have laid claim to be the first Interstate in the United States.<ref name="first interstate">{{cite web |title=The Interstate Highway System |url=https://www.eisenhower.archives.gov/highway.htm |url-status=dead |archive-url=https://web.archive.org/web/20070127073129/http://www.eisenhower.archives.gov/highway.htm |archive-date=January 27, 2007 |access-date=January 30, 2007 |website=[[The Dwight D.

The construction of I-70 in Colorado and [[Utah]] is considered an engineering marvel, as the route passes through the [[Eisenhower Tunnel]], Glenwood Canyon, and the [[San Rafael Swell]].<ref>{{Cite journal |last=Weingroff |first=Richard F. |date=Summer 1996 |title=Dwight D.
