A mile later, these highways intersect Interstate 10 at a complex, three level high expressway interchange which the locals call the "Spaghetti Bowl."

The route turns northeast, becoming a rare example of a collector–express freeway in Texas (until the Pershing Drive exit) before entering New Mexico.

The northern Panhandle portion was originally assigned to State Highway 56, paralleling the Chicago, Rock Island, and Gulf Railroad.

US 54 from Haggerty Drive in northeast El Paso to the New Mexico state line is planned to eventually be upgraded to freeway status.

The route runs along Dyer Street through Northeast El Paso near Fort Bliss to its northern terminus at the New Mexico state line.

Highway signs in New Mexico direct westbound US 54 traffic to turn left on Edge of Texas Street at the state line to access Bus.
