Project Overview

Phase 1 of I-10 Express Lanes is located in the southwestern portion of San Bernardino County east of Los Angeles County. The project will widen the existing I-10 freeway between the Los Angeles/San Bernardino County line and I-15, a distance of approximately 10 miles. The project includes two tolled express lanes in each direction. 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.
