Boulder sits in Colorado, in the Mountain West, and most trips out of town start on the local highway network before joining the interstate system. Fill up before you leave — fuel is usually cheaper in town than at highway service plazas — and check conditions before longer drives, since weather in the Mountain West can change travel times considerably. The main corridor for trips listed on this page is I-80, so check for construction or closures on that route before setting out.
