Truxton Natural Crossover


Working within a tight schedule, Ames Construction built a new 2.75-mile railroad alignment with a flyover bridge in Truxton, Arizona. The project scope included building an elevated railroad bed, construction of a 10-span bridge over dry wash, and the installation of an arched tunnel.

Because the site was remote (along historic Route 66), the project team skillfully coordinated materials delivery, crews, and subcontractors so that they were at the site when needed, avoiding losses associated with time delays.

Water availability was also a challenge. Ames successfully negotiated with a bordering land owner for both water and borrow material.

Upon project completion, eastbound trains began traveling above westbound traffic without going over a typical switch, putting them in a better position when approaching New Mexico’s fueling terminal.
