The driving distance is approximately 900-1025 miles (1450-1650 km), typically taking at least two days with an overnight stop. The most common route involves I-70 West and I-15 South. While the primary interstate route is generally toll-free, travelers may encounter optional toll roads near Denver (e.g., E-470) or in the Los Angeles area (e.g., Orange County Toll Roads). Fuel costs are estimates and will vary based on vehicle fuel efficiency and prevailing gas prices. Consider vehicle maintenance, rest stops, and potential weather conditions, especially during winter months through mountainous regions.
