Around Kramer Junction, Caltrans proposed a $200 million project to realign and widen a 13.3-mile segment of  State Route 58 from 0.4 miles west of the Kern County/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 junction of U.S. Route 395/State Route 58 to replace the at-grade intersection between the two highways, which had long been an infamous zone of highway backups.
