Nevada → Arizona · Interstate 15
Heading out from Las Vegas, Nevada, toward Tucson, Arizona, the driver covers roughly 687 km (427 miles) primarily on Interstate 15, spending around 6h 33m between origin and destination outside peak hours. Departing from Las Vegas, the leading entertainment and conventions destination in the US Southwest, the route traverses areas with distinct economic profiles before reaching Tucson, the second-largest city in Arizona and gateway to the Sonoran Desert. Trip planning should always include checking road conditions, toll plazas, active work zones, and the regional weather forecast — winter storms, holiday weekends and summer construction can each extend the schedule meaningfully. Estimated fuel cost — based on 62.5 liters of regular unleaded at 0.92 USD/liter — runs about $57.50. Applying the IRS standard mileage rate (2025) reimbursement rate of $0.43/km produces a one-way reimbursement of $295.41.
