SBCTA in cooperation with Caltrans, extended the eastbound (EB) truck climbing lane (TCL) on Interstate 10 (I-10) from the existing EB off-ramp at Live Oak Canyon Road located in the City of Yucaipa, San Bernardino County, California to just east of the existing County Line Road EB off-ramp at the Riverside County line (Project) in the City of Calimesa. The extension of the TCL for approximately an additional 3-miles, which includes steep uphill portions, improves operations on the interstate by separating trucks and other slow moving vehicles from faster moving passenger vehicles. This Project reduces the frequency of truck-related accidents. The project began construction in March 2024 and was completed in August 2025.
