I-10 Express Lanes
Project Overview
SBCTA’s Interstate 10 Corridor Project is comprised of three phases of improvements to benefit the movement of both people and goods on this facility that is important to both San Bernardino County residents and to the local and national economy. The first phase, stretching 10 miles from the Los Angeles County line to I-15, opened in late August 2024. SBCTA is preparing for the second phase of the SB Express Lanes on Interstate 10, stretching 11.1 miles from I-15 to Pepper Avenue in Colton. Advertising for bids for the project are expected for summer of 2025 with construction slated to begin later that year. The third and final future phase of 12 miles will be from Pepper Avenue to Ford Street in Redlands.
For the Phase 1 project, a single new lane was constructed and combined with the existing HOV lane to provide two tolled express lanes in each direction. The lanes will be available to HOV 3+ vehicles at a discount. In addition, lanes to assist drivers getting on and off the freeway (auxiliary lanes) were constructed in selected locations.

In Phase 2, single toll express lanes (also referred to as managed lanes) will be constructed (where there are currently no HOV lanes). Together, these express/managed lanes will open up a new opportunity to provide travel time incentives to transit, shared-ride vehicles, and zero-emission vehicles. Phase 2 will also construct three strategic eastbound (EB) auxiliary lanes or acceleration lane extensions and one westbound (WB) auxiliary lane to improve truck operations and safety, as shown in the graphic. The I-10/I-15 interchange is ranked the 10th most critical truck bottleneck in the U.S. by the American Transportation Research Institute, and these improvements will help to relieve congestion in the vicinity of that interchange.
