The route travels eastward along the former location of Fred Wilson Avenue, just north of Fort Bliss National Cemetery.

The route then jogs southeast then northeast, squeezing between the runways of Biggs Army Airfield and El Paso International Airport.

The route then turns back to the east and reaches its eastern terminus at Texas State Highway Loop 375.
