Interstate 8
Interstate 8 is an interstate highway in the southwestern United States. It runs from the southern edge of Mission Bay in San Diego, California, almost at the Pacific Ocean, to the junction with Interstate 10, just southeast of Casa Grande, Arizona. In California, especially from eastern San Diego County to points east, Interstate 8 runs very close to the Mexican border. At points in eastern Imperial County, the border is no more than two miles south of the interstate.
