RCTC, in partnership with Caltrans, is proposing the I-10 Pass Express Lanes Project. The project would add at least one Express Lane in each direction along I‑10 between SR‑60 and SR‑111 through the San Gorgonio Pass. The new lane is intended to improve reliability, safety, and travel choices along this heavily traveled corridor.

The I-10 Pass Express Lanes Project would:

• Improve efficiency of travel and travel time reliability in the San Gorgonio Pass
• Improve safety and expand travel options on I-10
• Support carpooling, transit, and express bus services to reduce vehicle miles traveled

RCTC is preparing a Project Study Report – Project Development Support (PSR-PDS) to clarify the project’s objectives. This report will study two potential managed lane alternatives and outline the engineering, environmental, traffic, and community engagement activities required before the environmental review begins. The study will also evaluate design concepts, assess potential traffic benefits and environmental considerations, and identify right-of-way and utility needs. RCTC will engage with local communities and stakeholders, and explore funding and tolling strategies during this phase of the project.
