New-Mexico

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.

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.
