Interstate 15 Maps -- Overview of I-15

Interstate 15 is one of the few Interstate Highways to run north to south from border to border It links the USA to Canada, our neighbor to the north, as well as to Mexico, our neighbor to the south. (Actually, I-15 stops a few miles short of the Mexican border...but it comes so close, that it deserves to be called a "border to border" freeway.)

Most of the length of I-15 is very quiet. It runs through many more miles of open countryside than it spends carrying motorists through the midst of city traffic. You'll have little trouble with traffic jams along its route except for the very few big cities through which it passes (Salt Lake City, Utah and Las Vegas, Nevada, specifically.) However, once Interstate 15 goes south into metro Los Angeles and San Diego, it clogs up plenty!
