You're standing in your driveway in the Valley of the Sun, coffee in hand, wondering exactly how many miles from Phoenix to Las Vegas you're about to put on your odometer. It’s a classic desert pilgrimage. Most people just punch it into Google Maps and assume the blue line is gospel.
Actually, the distance is about 297 miles if you take the most common route, US-93.
But distance is a funny thing in the Southwest. 297 miles of wide-open Arizona pavement feels a lot different than 297 miles of stop-and-go traffic on the I-95 corridor out East. You can usually knock it out in about four and a half to five hours. That is, if the universe is on your side.
Road trips are rarely about the shortest distance between two points, anyway.
The Breakdown of the 297-Mile Trek
Most drivers start by hopping on the I-17 North before quickly transitioning to the US-60 West through Surprise and Wickenburg. This is where the miles from Phoenix to Las Vegas start to feel "real." Wickenburg is basically the gateway. Once you clear that town, you’re committed to the US-93.
It’s roughly 250 miles of US-93 alone.
The road has changed a lot. People who grew up here remember when US-93 was a terrifying, narrow two-lane strip known as "Blood Alley." It was brutal. Thankfully, the Arizona Department of Transportation (ADOT) has spent years—and a lot of tax dollars—widening massive sections of it into a divided four-lane highway. It’s much safer now, but you still have to respect the desert.
Why the Mileage Varies
Depending on where you live in the Phoenix metro area, your total distance could swing by 40 miles.

If you’re leaving from Chandler or Gilbert, you’re looking at closer to 320 or 330 miles because you have to navigate the entire Phoenix freeway system just to get to the edge of town. Conversely, if you're starting in North Scottsdale or Peoria, you might shave 20 miles off the trip.
Then there’s the Kingman factor.
In Kingman, the US-93 merges with I-40 for a short stint. This is a common spot for people to get turned around. You aren't just driving in a straight line; you’re navigating a series of transitions that can add "ghost miles" to your trip if you miss an exit.
Is the Scenic Route Worth the Extra Gas?
Sometimes, you don't want the 297-mile sprint. You want the experience.
If you decide to go up through Sedona and Flagstaff (I-17 all the way up) and then cut across on the I-40, you’re looking at about 340 miles. It’s longer. It’s significantly more expensive in terms of fuel, especially with the climb up the Mogollon Rim.
But man, it's beautiful.
You trade the scrub brush and saguaros of the Sonoran Desert for the massive Ponderosa pines of the Coconino National Forest. Is it worth adding 45 miles to your miles from Phoenix to Las Vegas calculation? If it’s summer and 115 degrees in Phoenix, absolutely. The temperature drop alone is worth the extra hour of driving.

The Hoover Dam Bypass Shift
We have to talk about the Mike O'Callaghan–Pat Tillman Memorial Bridge. Before 2010, the "miles" weren't the problem—the dam was. You used to have to drive across the top of the Hoover Dam. It was slow. It was a security nightmare after 2001.
Now, the bridge carries you nearly 900 feet above the Colorado River. It didn't significantly change the physical miles from Phoenix to Las Vegas, but it changed the "time-miles." It shaved about 30 to 40 minutes off the trip by bypassing the hairpin turns and tourist pedestrians on the dam.
Survival Tips for the 300-Mile Stretch
The stretch between Wickenburg and Wikieup is... lonely.
You’ll go miles without seeing much more than a Joshua tree or a stray cow. Here’s the thing: your phone will lose service. It’s almost a guarantee in the canyons.
- Gas up in Wickenburg. Seriously. The gas prices in Wikieup are traditionally some of the highest in the state because they know they've got you cornered.
- Watch for Elk. North of Kingman, especially near the Nevada border, big game is a real threat at night. Hit an elk at 75 mph, and your Vegas trip ends in a ditch.
- The Nothingness. There's a section of US-93 that is just flat, shimmering heat. Keep your cooling system in check.
Actually, if you’re driving an EV, you need to be even more surgical. Tesla has a decent Supercharger network in Wickenburg and Kingman, but if you’re driving a non-Tesla EV, you need to map out your CCS chargers carefully. The miles from Phoenix to Las Vegas are hard on a battery when the AC is cranking at max.
The Reality of Traffic and Construction
Don't trust the odometer alone.
ADOT frequently runs construction projects on the US-93 to continue the expansion to a full four-lane divided highway. This can turn a 300-mile trip into a six-hour ordeal.

Also, Sunday afternoon? Don't do it. Everyone from Phoenix who spent the weekend in Vegas is heading south. Everyone from Vegas who visited the Grand Canyon is heading home. The merge in Kingman becomes a literal bottleneck.
I’ve seen traffic backed up for 10 miles at the I-40/US-93 interchange. Suddenly, those miles from Phoenix to Las Vegas feel like a marathon. If you can, travel on a Tuesday or Wednesday. The road is practically yours.
The Hidden Pitstop: Nothing, Arizona
You’ll pass a place called Nothing. It’s an uninhabited ghost town. It’s basically just a sign and some ruins now. It serves as a reminder of how harsh this 300-mile stretch can be.
People used to live there. Now, it's just a landmark. It’s a good spot to pull over, stretch your legs, and realize how much territory you’re actually covering.
Navigating the Final Approach into Nevada
Once you cross the bridge over the Colorado River, you’re in Nevada. The speed limit changes, and the Nevada Highway Patrol doesn't play around.
The last 30 miles into Vegas take you through Boulder City and then onto the I-11. The I-11 is a relatively new interstate that has replaced the old stoplight-heavy route through town. It’s smooth, fast, and brings you right into the heart of Henderson before dumping you onto the I-15 or the 215 Beltway.
Total trip? Usually 290 to 310 miles depending on your final resort destination on the Strip.
Actionable Next Steps for Your Trip
To make the most of your drive and handle the miles from Phoenix to Las Vegas like a pro, follow this checklist:
- Check the ADOT "AZ511" App: Before you leave Phoenix, check for any closures on US-93. It’s better to know about a two-hour delay before you’re stuck in the middle of the desert.
- Hydration is Non-Negotiable: Carry at least a gallon of water per person. If your car breaks down in the Mohave, you aren't just bored—you're in a survival situation.
- Download Your Maps: Since signal drops are common near Wikieup, download the offline version of your route on Google Maps or Apple Maps.
- Time Your Departure: Aim to leave Phoenix by 6:00 AM to beat the heat and the heaviest traffic, or wait until after 7:00 PM if you're comfortable with night driving and watching for wildlife.
- Stop in Kingman: Use this as your halfway point. Grab food, stretch, and check your tires. The pressure changes can be significant as you shift elevations.
The drive is a rite of passage. It's roughly 300 miles of some of the most starkly beautiful scenery in the American West. Just respect the distance, keep an eye on your gauge, and don't speed through the small towns.
