Desert Driving

Interstate 40 replaced Route 66 as the primary east-west freight corridor across the American Southwest, and it has inherited all of Route 66’s exposure to one of the most demanding environments a highway can occupy: desert heat, expansive terrain, sparse services, and a climate that destroys road infrastructure faster than maintenance budgets can keep up with it. Between the California border and the Oklahoma state line, I-40 passes through approximately 1,000 miles of some of the roughest pavement on the US interstate system.

California State Route 138 connects Palmdale and the Antelope Valley to Interstate 15 near Phelan, running approximately 60 miles through the high desert of San Bernardino County. It is a two-lane highway — undivided, with no median, minimal shoulders, and narrow lanes that leave virtually no margin between opposing traffic streams. It has been called “Blood Alley” by locals and emergency responders for decades, and the name was earned.

What Makes CA-138 Dangerous

The danger on Route 138 is structural. The road was built when traffic volumes were a fraction of what they are today, and it has not been significantly upgraded since. The result is a highway that handles modern traffic volumes at modern speeds on a physical design that belongs to a different era.

The stretch of US Highway 285 running through southeastern New Mexico and into West Texas is called the Death Highway. It is not a marketing name or a dramatic exaggeration by journalists — it is what the people who live along the route, the emergency responders who work it, and the drivers who haul freight on it call it. The name reflects a statistical reality: this corridor has produced a per-mile fatality rate that places it among the most dangerous rural highways in the United States, and the primary reason is the Permian Basin oil boom.

Interstate 15 between the Inland Empire and Las Vegas is one of the highest-volume freight and passenger corridors in the American West, and one of its most deadly. The 150-mile stretch through the Mojave Desert from the Cajon Pass summit to the Nevada state line combines extreme summer heat, monotonous open-road conditions that encourage speeding and drowsy driving, and one of the most notorious truck grades in California — all on a corridor that sees over 50,000 vehicles per day.
