'''Interstate 8''' (I-8) is an [[Interstate highway]] in the southwestern [[United States]]. It runs from the southern edge of [[Mission Bay, San Diego, California|Mission Bay]] at Sunset Cliffs Blvd. in [[San Diego, California]], almost at the [[Pacific Ocean]], to the junction with [[Interstate 10]], just southeast of [[Casa Grande, Arizona]].<ref name="Google">{{cite web|publisher=[[Google Maps]]|url=http://maps.google.com/maps?f=d&hl=en&geocode=2863822521104466740,32.754740,-117.235610&saddr=I-8+E+%4032.754740,+-117.235610&daddr=32.820893,-111.690445&mra=mi&mrsp=1,0&sz=14&sll=32.812382,-111.692848&sspn=0.032606,0.05785&ie=UTF8&ll=32.87036,-114.345703&spn=4.17026,7.404785&z=7|title=Overview Map of I-8|accessdate=2008-02-15}}</ref> In California, especially from eastern [[San Diego County, California|San Diego County]] to points east, Interstate 8 runs very close to the [[United States-Mexico border]]. At points in eastern [[Imperial County, California|Imperial County]], the border is no more than two miles (3 km) south of the Interstate.

Much of I-8 in the [[Imperial Valley (California)|Imperial Valley]] in California runs below sea level; in fact, at the New River near [[Seeley, California|Seeley, CA]], I-8 reaches the lowest land elevation in the entire Interstate system at -52 ft. (-16 m).
===Arizona===
{{main|Interstate 8 in Arizona}}
East of Yuma, the eastbound and westbound lanes invert; that is, the carriageways run on the left side of the median for roughly three miles.
Throughout the entire length of Interstate 8, it only intersects one U.S. highway (US 95 in Yuma).
