In the Kramer Junction area, Caltrans planned to realign and widen a 13.3-mile segment of State Route 58 from 0.4 miles west of the Kern/San Bernardino County line to a point approximately 7.5 miles east of Kramer Junction from a two-lane conventional highway to a four-lane expressway, and construct an interchange at the SR 58/US 395 junction to replace the then at-grade junction of SR 58 and US 395 in Kramer Junction. A groundbreaking ceremony for the Kramer Junction Expressway was held on January 19, 2018. The bypass was opened to traffic on October 24, 2019.
