New Orleans, LA → Phoenix, AZ

Departing New Orleans, you'll head northwest on Interstate 10 through Louisiana and into Texas, where you'll stay on I-10 for most of the first leg toward San Antonio. From there, the route transitions to Interstate 37 north toward Corpus Christi before connecting to US Route 77 and eventually rejoining I-37 as it merges into I-10 near San Antonio. The highway system becomes more straightforward as you continue westward on I-10 through the vast expanse of West Texas, passing through El Paso after roughly 22 hours of driving. This stretch is dominated by the high plains and desert landscape, with elevation gradually increasing as you approach the Rocky Mountain foothills and Arizona's border.

The terrain transformation along this route is dramatic and worth noting. You'll begin in the humid, subtropical lowlands of Louisiana, gradually transitioning through the pine forests and rolling hills of East Texas before entering the arid Chihuahuan Desert region around Midland and Odessa. The landscape becomes increasingly sparse and rugged, with wide-open vistas dominating the drive through West Texas. As you cross into New Mexico and Arizona on I-10 heading toward Phoenix, you'll experience significant elevation changes, climbing from around 2,000 feet near El Paso to over 2,700 feet as you approach Phoenix.

Notable cities punctuate this journey, including San Antonio with its famous River Walk, and El Paso, which sits dramatically on the U.S.-Mexico border with striking Franklin Mountains as a backdrop. Though you're primarily on major interstates, this route offers surprisingly scenic moments, particularly through the Chisos Mountain region visible from I-10 and the desert landscapes near the Arizona state line. Most of the drive consists of straightforward interstate travel with minimal congestion outside of San Antonio and El Paso's urban areas, though you should expect isolated, rural stretches with limited services across West Texas.

For the most comfortable driving experience, plan this journey during fall or spring when temperatures remain moderate, especially through the desert regions. Summer heat can be intense and exhausting, making winter months preferable despite occasional cold snaps. The route is generally well-maintained year-round, though you should ensure your vehicle is in good condition before tackling the lengthy stretches of highway with sparse services.

Seasonal Driving Considerations

Mountain passes along this corridor can be treacherous from October through May, with chain requirements, road closures, and whiteout conditions at higher elevations. Summer brings its own challenges — afternoon thunderstorms are common above 7,000 feet, and construction season narrows lanes on key highways. Always check pass conditions before departing, and carry emergency supplies during the colder months.
