The Kramer Junction project is located in the County of San Bernardino, north of existing SR-58. The junction begins at the Kern/San Bernardino County Line and ends 7.5 miles east of Highway 395. This project aims to implement route continuity, increase capacity, reduce congestion, improve traffic safety, provide a grade separation, include multiple animal crossings, and provide new state route access.
