I-10 Corridor Project Overview

The I-10 freeway is a critical transportation corridor through San Bernardino County used by residents, businesses and visitors. It's also a major trucking route between Southern California and the rest of the country as goods movement is vitally important for the local and national economies. Up to 263,000 vehicles and more than 20,000 trucks travel through this corridor each day.  

As our region grows, travel will also increase. As a result, we continue to see congestion grow during many hours of the day. This reduces time people can spend at home with family, friends, or engaging in activities of their choice.

To address these challenges, San Bernardino County Transportation Authority (SBCTA), the council of governments and transportation planning agency for San Bernardino County, studied alternatives as part of the I-10 Corridor Project to keep traffic moving. The solutions studied were designed to provide choices to motorists when driving along I-10 and to encourage economic growth, a sustainable environment and a high quality of life for everyone who lives, works and travels in and through San Bernardino County. In November 2015, SBCTA reconfirmed Express Lanes as the Locally Preferred Alternative. And in July 2017, the SBCTA Board of Directors approved the environmental document and the construction of the first phase of the I-10 Express Lanes. The Final Environmental Environmental Document for this project can be viewed here.
