The direct driving distance is about 1,357 to 1,420 miles (2,184-2,285 km). The primary route typically involves Interstate 10 West. Fuel costs are estimates and depend on vehicle fuel efficiency, current gas prices, and driving habits. Major interstate routes are largely toll-free, but some urban areas in California (e.g., Orange County toll roads) and around Austin may have electronic tolls. Consider breaking up the journey over at least two days.
