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, is currently under construction. The second phase, stretching 11.1 miles from I-15 to Pepper Avenue in Colton, is in design and the final funding components are being sought to enable construction to begin in 2024. 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 is being 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) are being constructed in selected locations.

Phase 1 Bridge Map

Eighteen bridges throughout the corridor will either be replaced, widened, or improved to accommodate the widening of the freeway. Click here Interactive project map to learn more about the bridges.

Phase 1 – ALERT: Westbound I-10 Access from Euclid Avenue

Scheduled for May 20 at 9:00 p.m., the westbound (WB) I-10 on-ramp from southbound (SB) Euclid Avenue will close for retaining wall construction for approximately 7 months. Motorists will be able to access the WB I-10 loop on-ramp at Euclid Avenue via a new extended left-turn only lane approaching 8th Street to 7th Street – lanes will shift to the west to create this new left-turn only lane. Alternatively, motorists can use 9th Street to Mountain Avenue to access the WB I-10 on-ramp at Mountain Avenue. Access to WB I-10 for motorists travelling northbound (NB) on Euclid Avenue will remain the same.

Please note, parking on SB Euclid Avenue from 8th Street to 7th Street will be prohibited. Driveways will remain accessible and there will be no changes to resident mail, deliveries, or trash services.

In Phase 2, single toll express 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 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 9th 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.
