ABOUT THE PROJECT
Phase 1 of SB Express Lanes is located in the southwestern portion of San Bernardino County east of Los Angeles County. The project will provide choices on the I-10 freeway between the Los Angeles/San Bernardino County line and I-15. The project includes two express lanes in each direction to offer trip reliability and ease congestion. In addition, lanes to assist drivers getting on and off the freeway (auxiliary lanes) will be constructed in selected locations. West of Haven Avenue, a single new lane will be constructed and combined with the existing HOV lane to provide two express lanes in each direction. The HOV lane will still be available to motorists, but will increase from 2+ to 3+. East of Haven Avenue, two express lanes will be constructed.
Walking on the freeway is unsafe. In case of an emergency, please dial 9-1-1. For non-emergency Freeway Service Patrol (FSP) services, call the California Highway Patrol (CHP) at (909) 428-5400 or use the nearest Call Box for assistance. Drivers or passengers of a disabled vehicle stopped on a freeway may walk to the nearest exit, in either direction, on the same side of the freeway upon which the vehicle is disabled, or to the nearest Call Box for assistance. For the safety of the public and our crews, unapproved access to construction sites and property related to project construction is prohibited.
